Please check our delivery information page for further details regarding our delivery policies. We are happy to answer any questions you may have regarding stock and custom items.

Direct replacement kits: All the big brake conversion kits we retail are direct bolt on replacement kits. This means that modifications are not required to the vehicle to fit the new calipers, rotors and parts. The kits are supplied with vehicle specific caliper brackets which aid in fitment. 

How long should it take to fit each kit? We estimate that 1 hour per side should be more than enough time to complete a fitment. Once you have removed the original OEM parts, the new parts will bolt straight on in their place providing your upgraded braking power.

Hi Spec - Audi TT 335mm Monster 4 Conversion Kit

Information: This Hi Spec Motorsport 335mm Monster 4 conversion kit will fit your Audi TT. The Hi Spec Monster kit isfor the heavier road car, the four piston Hi-Spec Monster 4 Conversions are available with disc sizes ranging from 310mm to 360mm. The Monster caliper has a pad one third longer than the Billet 4 which gives a greater pad surface area which in turn increases surface grip. The pad profile allows much larger disc sizes giving increased leverage, higher rotation speed of the disc relative to the pad and more surface area to assist with heat dissipation with the net result of massive stopping power.

What does a full conversion kit do? This full kit combines a Monster-4. 4-pot alloy caliper with large two-piece discs to give a significant increase in stopping power. The improved stopping power of the calipers joins forces with the greater leverage and heat dissipation properties to take braking performance into another league.

Fitting these alloy calipers and light weight one or two-piece discs has the added benefit of reducing unsprung weight. This is more important than just Losing weight from the car. Losing unsprung weight means better handling and response from dampers.

What is a .Monster-4. caliper? With larger pistons and a pad size 33% bigger than Hi Spec's Billet-4. caliper, the Monster-4. is better suited to medium to heavy weight cars or those with serious power. It is CNC machined from aerospace grade billet aluminium resulting in a super-rigid caliper with almost no flex, (a common problem with other alloy calipers). The Monster-4. also features integral dust seals, internal fluid transfer galleries and a fully anodised finish in a choice of colours.

What's included? Everything that is listed below and the additional extras which can be picked from menu above. We like to provide everything that is required for direct fitment with no messing about. We strongly recommend these kits as they are incredible value for money.

Wheel clearance: Before ordering please check your wheel clearances.
