Hi, I have just bought an A3 1.8 Turbo and I'm planning to 'improve' the performance a little? There is a lot of talk about regarding re-maps and who's the best etc. So far I think Jabba sport will be able to offer the best 'custom' set up so I have that noted. I also want to fit a Miltek cat back, Miltek Hyperboost DV, Cold Air Induction kit and then do some suspension mods, wheels and brakes! Not a lot then? I hear a lot of talk saying 'OILED' filters will eventually wreck the MAF sensor, is this true? Can anyone recommend a good air filter? What kind of SPRING kit is best for the 1.8T? What size wheels can I get under the rims without comprimmising on ride quality? I plan to fit up rated brakes on the standard size - What are the best performing replacement out there? Last one, Does anyone know where I can get an S3 rear bumper? Many Thanks in advance.
