A genuine Brembo 328mm cross-drilled replacement rotor, 28mm thick, for a Brembo Gran Turismo big brake system as fitted to the Mercedes C-class / including AMG (W203).
This is the iron rotor ring on its own. It bolts to the aluminium bell already on the car, so the bell and its bobbins are not included. If your bobbins are worn, order a bobbin kit at the same time.

This rotor is handed, so the left and right parts are different. Tell us which side you need, or order two and we will send a matched pair.
Price shown is for one rotor.
Brembo recommends replacing discs in axle pairs and fitting new pads at the same time. Brake work is safety critical, so use a qualified technician and bed the discs in to the instructions supplied.
Will these fit my existing kit?
Replacement discs are specific to the kit and car combination in the listing: diameter, bell pattern, and offset all have to match. Check the listing against your kit, and if you are unsure which kit you have, send us a photo of the caliper and disc and we will identify it.
Drilled or slotted, which should I run?
Slotted discs deglaze the pad face and shed gas without the crack-propagation risk drilled holes carry under repeated heavy heat cycles, which is why track-focused drivers usually run slotted. Drilled looks the part and works well on fast road cars. Our guide on track day brake prep covers the heat management side.
Should I change pads at the same time?
If the old discs were worn or heat-checked, yes: old pad transfer material on new discs causes judder. Our guide on brake pad compounds helps you pick the right compound while you are at it.
Every brake kit here is built to order
We do not keep big brake kits on a shelf. Each one is put together for your car in the disc face, caliper colour and specification you choose when you order, so nothing is made until the order is placed. The site shows these as available because we can take the order and start it, not because it is boxed and waiting.
How long it takes
Brembo GT kits are made in Italy and run around six to eight weeks. Our UK built kits are quicker, and the exact time depends on the caliper and disc combination you pick. Ring us on 0115 989 3488 before you order and we will give you the current lead time for the kit you are looking at, not a general one.
Working to a date
If the car is booked in, or it is off the road, tell us the date when you call. We will tell you straight whether the kit will make it, and what the alternatives are if it will not.
Worth two minutes before you order
Wheel clearance catches people out. Send us your wheel make, size and offset and we will read it against the caliper clearance drawing first, because a kit that is already being built for you is not something we can simply swap.
