Front is much easier and cheaper to do than the back, but it's very involved to get a 135i up to 1M specs suspension-wise. I just meant there's not much different in terms of the actual powertrain (except the differential). The wide body and the fat wheels were the biggest challenge to overcome in getting a 135i to "equal" a 1M, but that seems solved now. Same engine with mostly the same components, same tune and cooling upgrades as the PPK.. still awesome though  |
Are you doing the rear M3 camber link conversion?
I believe Dan from United quoted $3700 for the oem 1m kit for the 135i...If I remember quickly. I would only get the kit to run wider wheels and tires for the track.
