Cool, all advice is greatfully archived for reference!
As far as stability, I've got two issues -- one is that the car wonders a bit down the straight. I was going to add a bit more front toe-in to try & solve that, so we're on the same page there.
The other area is that it's easy to break the back end loose. I'll try dialing out some braking. Likewise on softening the rear -- I removed the rear sway bar, and I was planning on going softer in springs if that doesn't do it.
What I'm wondering is if the wider track / wider tires won't help at the same suspension settings. That way I don't have to worry about getting so soft that I start getting body roll / traction rolls.
thanks alot,
dave.
