There's quite a lot of body roll - I'm going to have to put the stiff spring set back in.

Why is body roll bad? Running out of camber?

It's a BMW with a macstrut...what else could it be?

:eeps:

Body roll? What body roll?

Shitty transitional response. Camber is also an issue.

Why did you take them out?

Seemed like a good idea at the time.

Or more accurately, roll stiffness.

And just think, all that positive right side camber with double wishbones ;)

Wouldn't it still be negative until the moment where the car loses traction and goes airborne? With all the weight of the car on the right wheels, I'd think there's be even more negative camber.

Not really. Negative camber means that the top of the tire is angled towards the car. Strictly speaking, it's always negative unless you hit something or have truly unbeleivably bad geometry. Whenever we say "goes positive" we're referring to the tire's relationship with the road. In this case, unmitigated body roll has that car cornering on the sidewalls. Since it's FWD, it's much harder to cure without creating lots of understeer.

And Ed, don't give me any of that worthless crap about how that particular DW suspension is set up. DWs have far greater potential than struts, but only if they're set up to take advantage of it.
