Dear All, As mentioned above, i want to know the whether too much negative offset in OEM wheels can cause tire vibrations. Current car is an E46 318ci with stock undercarriage. Wheel hub is still using stock and standard which sits quite inside the fender. Current wheels are OEM 17" with ET37 offset. My mechanic already gave me a preamp that i will experience slight vibration and on-wheel balancing can only reduce it but not cure it completely. As he said, i did feel slight vibrations randomly at any speed depending on road conditions. Should i change back to wheels within my 318ci spec or there's something wrong with my car ? For guys who didn't know my car, its running on 1JZGTE engine with custom driveshaft using Toyota Crown's and E46 flange to rear axle with 3.46 differential.
