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.
Yes but when we tried with regular hub centric ring, the wheels couldn't fit. The difference between the wheel bore is only by 2 mm so we have to manually shave off the extra metal to fit the wheels in completely.
there goes your answer...
there is bullshit reason wrong wheel offset = vibrate... nope.. dont ever believe that...
the reason wheel vibrate:
-damaged wheel (bent/wobble)
-damaged tyre (wire inside broken/out of balance)
-damaged wheel bearing
-wrong hubcentric fitment <--- your real reason by manually shaving that wheel/hub area to fit...making it even worse....dont pour money somewhere else... settle this properly, then the vibration issue will be gone for good
