ive lowered on coilovers........measured from edge of fender to middle of wheel center cap..........as stated in this guide http://bd8ba3c866c8cbc330ab-7b26c6f3...horizontal.pdf front left and right + rear right are 100% same level.......rear left is a bit lower and i mean a teeny bit id say about 2-3mm (at a guess) what i did notice was the perch on the rear left has been adjusted more than the rear right but still sits 2-3mm lower. is this normal ? also both rears are a pain to adjust as when i tried to adjust both the collars and perches were turning instead of just the collars. thought it be a lot easier. now i have noticed when im coming off a speed hump(only when im coming off) rear left has a noise, can only describe it as if a bolt is loose,but nothing is.... i only removed shocker and spring with clamps nothing else on the rear as the guide says above because i found different instructions on another site. ALSO WHEN I TRIED ADJUSTING REAR ...I TURN PERCHES AND SLEEVES TURN TOO....BUT ARE FITTED CORRECTLY....SO WHY ?????????
