I know the caliper is bigger, hence one of the reasons I got the bigger rims, to clear it. I also wanted to get a bit more traction with the m3 motor, the stock size steelies aren't doing it for me, thouhg I guess 17X9 is a little big... oh well I expected to have to roll the fender.
So what you are saying is there is no offset difference between a '95 e36 m3 and a '95 e36 318ti, despite it being a different spindle and rotor, from the chart going from a 286 x 12mm solid to a 315 x 28mm vented? the wheelbase for the two cars is identical? except I know the stock Wheel offsets which are 38 and 41 respecitvely if I remember correctly?
I know you may not know what BMW was thinking when they did it but... do they have different wheel offsets just to allow the m3 a wider stance and accomodate a larger wheel, but not have anything to do with where the hub actually is... like if I measured hub to hub in the front of an M3 and a 318ti it would be exactly the same distance (neglecting individual car to car differences because of manufacturing tolerances and worn parts)
The next question I have is...(and I apologize it prob doesn't belong in the brake thread, but it is related) must I have the m3 control arms to fit the spindle and also the offset control arm bushings? or can I just bolt on with the 318ti control arm centered bushing, because I don't want the extra camber right now from the m3 because lowering the car already changes the camber angle ...
I really have been trying to do my research but haven't come up with a difinitive answer yet. I will probbaly just order the TMS hub extender and 7.5mm spacer and call it a day... but I will still need to know about the control arms.
The help is greatly appreciated.
