my 05 sti has started to produce a buzzing sensation through the accelerator padal at 3000 rpm, this is felt more at high speed 4th, 5th + 6thgear, no noise heard. only problem is i changed a few things on the car at the same time eg. clutch, flywheel, up pipe , 2 new front tyres, all standard genuine parts. can you get clutch plate to flweel in a position to cause a balance problem? or is it new tyres causing wind up at speed, any ideas please

 

If your rear tyres are tired and emotional (bald) then it's one of your diffs trying to explain that it's unhappy..... got that t-shirt !
