It does look like castor may be better with the e46 stuff too. E36 stub axle suts just behind the strut line whereas an e46 stub axle sits just about on the strut line.HairyScreech wrote:Did a little bit of checking when I got home, one of the issues with the e36 bits is the steering angles, which is largely affected by the width to wheel base ratio.
Constructing a few lines from the track width to the center point of the rear axle and checking the angle they produce gives me.
E30 - 30.61 deg included angle.
E36 M3 - 29.51 deg included angle.
E46 - 30.86 deg included angle.
Now provided that these cars are set up for neutral scrub radii then the e46 hubs might solve the steering angle issues.
That is given the castor etc works out as well.
Other potential issues are - how much, if any, would it increase the front track width? Would that result in clearance probs - particularly in my case using 15mm spacers to clear the brakes. And would there be sufficient suspension travel using e46 struts or would they be riding the bump stops all the time? Albeit perhaps less of an issue if using coilovers.
I may yet mock something up whilst I'm too skint for track days to see if I can answer some of these questions.
