>>>There seems to be a difference of opinions here. Hopefully, I'll be able to verify on wednesday with a smart camber gauge and take out the coils and investigate. As far as why I care about this, how's the tire wear on the track. I'll be able to get pyrometer readings nextmonth but I'm looking for a good starting point. It's ridiculous how little camber is available in the front. What do they do with the Exige cup cars? I can't imagine -.8 being enough to optimize the contact patch.<<<
Camber changes will never totally match theory due to things like rubber bushings, uneven ground during casual measurements. But if you yank two 1 mm shims you should achieve somewhere near the expected amount of change. I think they give the guideline as a starting point, you should always measure the actual.
Our double a-arm suspension has a useful camber curve. On the Cup cars they have a much lower static ride height so they can achieve more static camber. That is the suspension gains negative camber as it is compressed. Lotus generally tunes the Elise to run out of front grip first.
