After reading threads on here ( and my personal experience ) ive noticed there are a few options as upgrades on an S3. I was wondering what people use and how they rate them. Ive tried uprated disc and pads... Namely zimmerman cross drilled discs and pagid fast road pads... they worked well on my Mk3 Vr6 but didnt seem to work as well with the weight of the S3. I tried the same discs with porsche Boxter S callipers with standard porsche pads. These didnt fit sraight behind the standard S3 wheels and needed spacing which i wasnt a fan of to be honest. This set up seemed to work but for the money i didnt feel it was that good. Pedal feel was spongey and it was like it needed one and a half press of the pedal to get a real good bite. They looked good though and people assume you have a fast car because of the big red callipers. Ive now had my Brembo GT jnr kit on for 2 years and when i got them they used the discs and pads that come with the kit. These worked fine but when it was time to replace i was shocked. I couldnt afford the price of the drilled discs and pads at the time so i looked for other options. I tried standard discs from seat and Mintex pads. This worked ok but the pads did feel soft after a few hard stops. fading and giving no confidence. As things stand now i have Grooved discs all round from CNR in chesterfield ( which i believe are Standard seat leon cupra R Brembos with CNC milled grooves) with Ferrodo Ds2500 pads up front and standard mintex pads at the back. After fitting these i wasnt pleased at all. But i then realised i may have boiled the brake fluid when i was trying the mintex pads. I changed it all to ATE super racing blue fluid and ive never looked back ! The pedal feels firm and the bite is good. Ive only tried them on a track session once but they are the best set up ive tried to date. What other set ups have people tried and how have they got on with them? Im thinking of using 300mm rear discs from an S4 when my current discs wear out but im not sure it will make that much diffrence.
