Does anyone know the weight of the stock BMW 18" sport rims (397)?
Also, I assume the stock BMW 397s are cast wheels and not forged, but I have found some good wheels that are close to the weight of good forged wheels for my 335i.... But I really hope some one either knows the weight of the stock rims or they weight them for us once they get their new setup....
Thanks lots in advance,
P.S. My response to the OP's question would be to stay conservative for looks and comfort. stay with 19s, but go more aggressive with a wider setup of: 19x8.5/245s front & 19x9.5/285s rear. This is the F10 M5 type setup & it looks killer and handles like nothing you have ever experienced, unless you have driven a few Lambos/Ferraris like I have
( the car will be far more comfortable & look better... I never prefer a rubber band type tires, with next to no sidewall, that have to go on twenty's or larger anyway)
