I didn't realise that negative camber could be a good thing... thinking about it, I guess it makes sense. But I've hardly been posting misinformation?
Hehe. Anyway. So is there a difference in ride height between pre-87 and facelifted 88- models? I own an early '87 318, and I see a '91, end of line I guess, E30 320i parked in the car park at work. Both cars have the same bottlecap alloys and similarly profiled tyres (195/60 vs 175/75), but mine, the older 318 seems to have a larger gap between the wheel arch and top of the tyre. We're talking some distance here, a few inches. The later 320i has a much smaller gap, but the underside of both cars looks to be a similar height off the road. I thought it was just some kind of optical illusion but I'm used to being wrong.
I thought the facelift changes were basically cosmetic... new-style lights, different trim and bumpers etc, and not suspension based? Or were the fenders/wheel arches redesigned slightly too?
Wider radius wheels have a greater inertia... being like a "rotational mass"... that makes them harder to spin. As things with more weight need more force to lift, so wheels with a greater inertia need more force to spin. If your engine outputs the same amount of turning force torque but the inertia of the wheels is increased, the rpm of the wheels for a given rpm of the engine will decrease and the car will slow down.
Thanks for putting up with another question!
