Our Top Recommended Big Brake Upgrade Kits For Your Seat Ibiza MK3
Every Tarox kit on this page has 1.9 TDI in the title. Not one of the seven HiSpec kits names an engine at all, they just say Seat Ibiza Mk3 and leave it there. Two brands looking at the same car, describing the fitment in terms that do not line up. That matters, because most of the Ibiza Mk3s coming through the showroom for a brake upgrade are petrol cars, the Cupra and the FR, and the listing that ought to cover them is the one that has a diesel badge on it. Tarox’s own part codes on these three kits are Audi and Volkswagen codes, which suggests they are platform kits, but a factory code is not a fitment confirmation and we will not treat it as one. Ring us with the engine and the year before you order a Tarox kit for this car.
The second thing to know is that the box contents on this vehicle do not read the way HiSpec listings usually do. All seven HiSpec kits here include EBC pads and a bottle of DOT 5.1 fluid in the price. The two Monster kits add braided hoses as standard; the three Billet 4 kits list hoses as optional. Tarox fit Corsa pads at the factory and put braided hoses in the box on all three of theirs. So the gap between the two brands is a lot narrower here than the headline prices make it look, and on this page you can compare them almost straight across. The full Seat Ibiza Mk3 range is on the site if you want to browse it raw.
- All three Tarox kits are titled 1.9 TDI; all seven HiSpec kits just say "Seat Ibiza Mk3" with no engine named
- Ten front kits, £1,243.01 to £2,280.00 inc VAT
- Discs run 285mm to 360mm, so 15 inch wheels at the bottom and 18 inch at the top
- Every HiSpec kit here includes EBC pads and DOT 5.1 fluid, which is not how these listings usually read
- The 314mm Billet 4 is the cheapest kit on the page and the biggest of the three Billet 4 kits, which is backwards and flagged below
Two brands, two ways of writing the same fitment
Both companies machine their own calipers from billet aluminium and build each kit to order for the specific car. On the Ibiza Mk3 page the visible difference is how they word who the kit is for, and how much of the finished job arrives in the box.
Tarox
Built at the Tarox factory in northern Italy. Calipers CNC machined from European billet alloy, hand assembled and individually tested. Discs heat treated, CNC faced and hand balanced to 0.05mm. All three Ibiza Mk3 kits use the B32 six piston caliper, carry Corsa pads fitted at the factory and braided hoses in the box, and state full ABS and ESP compatibility. All three are also listed against the 1.9 TDI.
HiSpec Motorsport
Machined in Dartford from aerospace grade billet aluminium. Made to order, up to 28 working days, calipers anodised in black, red, blue, gold or silver. Seven kits here across three caliper families, none of them naming an engine. Every one includes EBC pads and DOT 5.1 fluid; the Monster kits add braided hoses, the Billet 4 kits list hoses as optional.
One external link worth bookmarking for Tarox: their wheel clearance template is the definitive check for spoke depth once you have the minimum diameter sorted.
The number that decides it: your wheel size
Minimum wheel diameter is a property of the kit, not of the car. A 335mm disc inside a Monster caliper takes up the same room on an Ibiza as it does on anything else we list it against, so every figure below is a published number. Every HiSpec figure matches that kit’s own published wording and the wider HiSpec catalogue for the same disc size, so there is nothing to flag on this vehicle. The Tarox figures were looked up individually against each kit’s own part code on tarox.co.uk, because Tarox genuinely publish different minimums for the same diameter on different cars.
One gap: the 323mm Tarox kit, part code KMAU0986, has no live page at the factory end, so no minimum is published for it. The 318mm and 330mm kits either side of it both come back at 17 inch, which is what we would expect it to be, but we are not going to print an expectation as a fact. Ask us and we will get it confirmed by Tarox before you order.
| Kit | Disc | Smallest wheel |
|---|---|---|
| HiSpec 285mm Billet 4 | 285mm, one piece | 15 inch |
| HiSpec 300mm Billet 4 | 300mm | 16 inch |
| HiSpec 314mm Billet 4 | 314mm | 16 inch |
| Tarox 318mm Sport | 318 x 26mm | 17 inch |
| Tarox 323mm Sport | 323 x 28mm | Not published by Tarox, ask us |
| Tarox 330mm Sport | 330 x 26mm | 17 inch |
| HiSpec 335mm Monster 4 | 335mm | 17 inch |
| HiSpec 335mm Monster 6 | 335mm | 17 inch |
| HiSpec 360mm Monster 4 | 360mm | 18 inch |
| HiSpec 360mm Monster 6 | 360mm | 18 inch |
HiSpec 285mm Billet 4: the only kit here that fits under a 15
If the car is still on its standard 15 inch wheels and you are not planning to change them, this is the whole shortlist. Nothing else on the page goes under a 15. It is also the only single piece disc kit here: the listed contents are two discs, two brackets and a hardware pack, with no alloy bells and no rotor-and-bell pack, which is how HiSpec describe a one piece kit. The general paragraph further down that same listing still talks about two piece discs, which is boilerplate that has not been trimmed. We go by the explicit contents list and we have flagged the wording.
For a road car on standard wheels it does the job it is meant to do. Four piston billet caliper in place of the sliding original, a bigger disc than standard, EBC road pads and fluid already in the price. Just read the next section before you order it, because the pricing on the Billet 4 range is not in the order you would expect.
- £1,254.00 inc VAT, EBC road pads and DOT 5.1 fluid included, braided hoses optional
- Clears 15 inch wheels, the only kit on this page that does
- 285mm one piece disc, the only single piece disc in the line-up
- Billet 4 four piston caliper, CNC machined in Dartford, five anodised colours
- Costs £10.99 more than the bigger 314mm kit below, so check that one first if you are on 16s
HiSpec 300mm and 314mm Billet 4: where the pricing runs backwards
Same caliper, two disc sizes, and both clear a 16 inch wheel. On paper this is a simple step up: pay a bit more, get 14mm more disc. On the site it is the other way round. The 314mm kit is £1,243.01 inc VAT and the 300mm is £1,464.00, so the bigger kit is £220.99 cheaper than the smaller one. It also undercuts the 285mm entry kit by £10.99, which makes it the cheapest kit on the whole page.
We are flagging that with HiSpec because we do not think it is deliberate. Until it changes, the honest advice is the obvious one: if you are on 16 inch wheels, buy the 314mm. You get the biggest Billet 4 disc available for this car and you pay the least for it. Garreth would not sell anyone the 300mm at that price while the 314mm sits below it.
- £1,243.01 inc VAT (314mm) or £1,464.00 inc VAT (300mm), EBC pads and DOT 5.1 fluid in both
- Both clear 16 inch wheels
- Two piece discs on alloy bells, straight vane rotors
- The bigger 314mm kit is £220.99 cheaper than the 300mm, which is backwards and flagged with HiSpec
- Billet 4 four piston caliper on both, braided hoses optional on both
Tarox 323mm and 318mm Sport: everything in one box
This is where the complete kit argument starts. Both of these arrive with Corsa performance pads already installed and vehicle specific braided hoses in the box, so once the brackets are on and the system is bled there is nothing else to buy. Both use the B32 six piston billet caliper on a two piece floating disc, billet steel rotor on an anodised alloy bell, balanced to 0.05mm. Choice of five caliper colours and four disc styles on both.
The pricing needs the same warning as the Billet 4 section. The 318mm kit is £2,050.00 and the 323mm is £1,748.98, so the smaller kit costs £301.02 more, and the 323mm runs a 28mm thick disc against the 318mm’s 26mm. Bigger, thicker, cheaper. We would take the 323mm and we would say so on the phone. Both are listed against the 1.9 TDI, so confirm the engine with us first if yours is a petrol car.
- £1,748.98 inc VAT (323mm) or £2,050.00 inc VAT (318mm), Corsa pads pre-fitted and braided hoses in both
- 323 x 28mm or 318 x 26mm two piece floating disc, balanced to 0.05mm
- B32 six piston billet caliper, hand assembled and tested in Italy
- The 318mm costs £301.02 more than the bigger, thicker 323mm; we would take the 323mm
- The 318mm clears a 17 inch wheel; Tarox publish no figure for the 323mm, so ask us and we will confirm it
HiSpec 335mm Monster 4 and Monster 6: the track pair
The Monster caliper takes a pad a third longer than the Billet 4’s, which is most of why it copes better with repeated heavy stops. The Monster 6 runs that same pad against six pistons instead of four, up to 63 per cent more piston area, and what you feel is a firmer pedal and finer control at the top of the travel. Both kits sit on a 335mm two piece disc with curved vane rotors and both clear a 17 inch wheel, so stepping from one to the other costs you nothing in wheel size.
There is £123.00 between them, the smallest step on this page. For an Ibiza that sees track days, not just the odd spirited B road, that is money worth spending. Both include EBC Redstuff pads, DOT 5.1 fluid and braided hoses, so like the Tarox kits above there is nothing left to add.
- £1,650.00 inc VAT (Monster 4) or £1,773.00 inc VAT (Monster 6), EBC Redstuff pads, fluid and braided hoses in both
- Both clear 17 inch wheels
- 335mm two piece discs, curved vane rotors on aluminium bells
- The Monster pad is a third longer than the Billet 4 pad; the Monster 6 adds up to 63 per cent more piston area on that same pad
- £123.00 between the two, the smallest price step in the range
Tarox 330mm Sport: the biggest disc that still lives under a 17
The dearest kit on the page and the one that gets the most disc under the smallest wheel. Tarox publish 17 inch as the minimum for this kit against its own part code, so a 330mm disc goes where a HiSpec 335mm goes and 16mm more than the biggest Billet 4 will manage. Six piston B32 caliper, two piece floating disc, Corsa pads fitted, braided hoses in the box, ABS and ESP compatibility stated.
The title on this listing says 6pot and Tarox’s own specification for the B32 says six pistons too. On a lot of the cars in this series the Tarox titles and the real piston count disagree, which is why we check every one. On the Ibiza Mk3 all three titles are correct and there is nothing to correct.
- £2,280.00 inc VAT, Corsa pads pre-fitted and braided hoses included
- Clears 17 inch wheels, looked up against Tarox's own page for this kit
- 330 x 26mm two piece floating disc, billet steel rotor on an anodised alloy bell
- B32 six piston caliper; title and factory spec agree, no piston count to correct here
- Listed against the 1.9 TDI like the other two Tarox kits, so confirm the engine with us first
If the car is on 18s
Two kits on this page ask for an 18 inch wheel, and both are HiSpec Monsters on a 360mm disc. The Monster 4 is £1,780.50 inc VAT and the Monster 6 is £1,863.00, and both include EBC Redstuff pads, DOT 5.1 fluid and braided hoses in the price. This is 25mm more disc than the 335mm pair above, on the same calipers, and here the pricing behaves itself: each kit costs more than the smaller version of the same caliper, which is more than can be said for the Billet 4 range. If the Ibiza is on 18s and doing track work, the 360mm Monster 6 is the biggest brake this car’s catalogue offers.
What is actually in each box
Across this series the usual pattern is that HiSpec price the caliper, disc and bracket and leave pads and hoses to you, while Tarox include both. The Ibiza Mk3 listings do not follow that. Every HiSpec kit here has EBC pads and DOT 5.1 fluid in the price already, and the Monster kits include braided hoses too. The only genuine gap left on the HiSpec side is hoses on the Billet 4 kits, which the listings mark as optional. Spec the two brands level and the price difference is the price difference, with no hidden extras to add on one side.

Prices include VAT and were correct on 16 August 2026. Two prices on this page do not follow the size of the kit. The 314mm Billet 4 costs less than both the 300mm and the 285mm, and the Tarox 318mm costs more than the bigger and thicker 323mm. Both are listed above exactly as the site has them and both are with the makers for a look. Neither has been quietly left out of the table.
Common questions
My Ibiza is a Cupra, not a 1.9 TDI. Can I still use the Tarox kits?
Possibly, but we are not going to promise it off the back of a listing title. Tarox list all three of their Ibiza Mk3 kits against the 1.9 TDI, and the factory part codes on them are Audi and Volkswagen codes, which suggests they are built around the shared platform hub. That is our reading of the part codes, and Tarox have not confirmed it. Ring us on 0115 9893488 with the engine, the year and the chassis number and we will get it confirmed by Tarox before anything is ordered. The seven HiSpec kits name no engine at all, so they are the simpler starting point while you wait.
Why is the bigger 314mm kit cheaper than the 300mm one?
We do not know, and we think it is an error. The 314mm Billet 4 is £1,243.01 inc VAT, the 300mm is £1,464.00 and the 285mm is £1,254.00, so the biggest of the three is also the cheapest. Same caliper, same pads, same fluid on all three. We have flagged it with HiSpec. Until it changes, anyone on 16 inch wheels should buy the 314mm.
Do the HiSpec kits come with pads, or is that extra?
On this car they come with pads. All seven HiSpec listings include EBC pads and a bottle of DOT 5.1 fluid in the price, standard road compound on the Billet 4 kits and Redstuff on the Monsters, both upgradeable when you order. Braided hoses are included on the Monster kits and listed as optional on the Billet 4 kits. That is not how HiSpec listings read on every vehicle, so keep it in mind when you compare this page against another car's.
What wheel size do I need for the 323mm Tarox kit?
Tarox have not published one for it. Part code KMAU0986 has no live kit page at their end, and we will not invent a figure. The 318mm and 330mm kits either side of it are both 17 inch, so 17 is what we would expect, but expectations are not what you want to be buying wheels on. Call us on 0115 9893488 and we will get the number confirmed by Tarox before you commit.
Will a big brake kit clear my aftermarket alloys?
Diameter is the first hurdle and the table above answers that. Depth is the second and it is car and wheel specific. HiSpec want 60mm from the face of your existing disc to the back of your spokes, and Tarox publish a printable clearance template you can hold against the hub. Give Cameron the wheel make, model and size on 0115 9893488 and he will check it against the kit you are looking at before it goes to build.
What we would actually fit
Start with the wheels, because they rule out more than anything else does. On standard 15s the 285mm Billet 4 is the only kit that fits, so that is the shortlist. On 16s buy the 314mm Billet 4: biggest Billet 4 disc for this car and, while the pricing stays as it is, the cheapest kit on the page by some way.
On 17s it comes down to how the car is used. For a fast road Ibiza that wants one delivery and nothing left to buy, Garreth’s money goes on the Tarox 323mm at £1,748.98 inc VAT, pads fitted and hoses in the box, and it undercuts the smaller 318mm by £301.02. For a car doing regular track days the HiSpec 335mm Monster 6 is the better tool, more pad and more piston area for £1,773.00, and it is made to your caliper colour in Dartford. On 18s the 360mm Monster 6 is the biggest brake this car has available.
Before you order any of the Tarox kits, ring Cameron on 0115 9893488 with the engine and the year. Those three listings say 1.9 TDI and the seven HiSpec ones say nothing at all, and that is a gap we would rather close on the phone than find out about at fitting.
