Hey, quick question.

What's the 'perfect' degree/angle for sw20 LCA's?

My boss was telling me about about his track setup cars how around 2.5-3 positive was perfect, and negative would create hopping. Problem is all I work on is GTR's, silvias and regular skylines, so when we set it up it's great for them. Thing is they all have a fairly even weight distribution compared to an SDub.

The car is a track car, so height isn't an issue. Will be attending Circuit, AutoX and possibly hill climb events.

Adjustable coilovers in right now, await decent LCA's so I can set/adjust. Can do my own wheel allignments and have experience with adjustable arms too.

Cheers.

I can say that lower is not better with the MR2. The guy who won the MR2 Trackday Challenge 2014, was a AW11. I am pretty sure it ran 30mm Roll Centre adjustment .
Mine has 25 front and 32 rear. What was more important was managing the bump steer in both front and rear. I did a lot of work to dial is out. Ended up with close to 5mm over the whole travel of the suspension. One thing you cannot remove without changing to A linkages, is the moving in the wheel base throughout the travel of the suspension but with bump steer and decent Roll Centre it does improve the handling. I also tightened up the chassis which help a lot.
