OK, so now you guys are 'spamming' Maui's thread... ;-)
Maui, I tracked mine twice the past 6 weeks and so far so good....I started with 650lb/in Front, 550 lb/in Rear using the QA1 Double Adjustable shocks and standard GT-40 sized Avon's (for now), and I have been making small adjustments from there. Another local RCR racer (Mahlon), I believe, started off with a slightly different approach, that is using softer spring rates with sway bars. Maybe he can chime in also...
You will probably spend more time setting up the front geometry, than the rear...
Good luck!
