qa1 or comp 3 way on the rear?
i am going with the qa1 12 ways in the front. is there any reason to get the 12 way adjustable in the rear? seems to be overkill to me. although i am no suspension guru- it just seems that the main place one would need to fine tune things would be in the front end- especially considering we are talking about something that's only gonna go 11's-12's in the quarter. i know the comps require removal to be adjusted- i am not too worried about that since it's in the rear only. just trying to save a few hundred if possible. what's the popular opinion qa1's all the way around or half and half?
*edit*
i will be using moroso trick springs

rear is more important than the front in drag racing. I'm cutting 1.6x 60'fts on 17's w/ stock springs(cut to lower), KYB struts, and WS6 sway bar in the front. When you launch the suspension pushes the diff. down, planting the tires. If the shocks are too loose, the rear will hit too hard and rebound, unloading the tires. If it's too stiff it won't hit the tires hard enough, never planting the tires. Puts double adjustables into a whol new light, now you can control the extension(downward) and the compression(upward) travel, letting the rear down as hard as possible, while allowing you to hold it down.
- not that letting the front jump up quicker doesn't help w/ weight transfer, but why leave the front end high in the air if you don't need too? Hell, we run front-end travel limiters to stop the front from dropping top much, causing to much weight transfer.(remember, upward is wasted motion when you're trying to go forward...)
- the rear suspension hooks the car. The front just transfers weight. Get the rear to hook, then figure out how much weight you need to throw back on the initial hit.

i never reall thought about the idea of the rear tires unloading- makes complete sense. guess i will go ahead and buck up for the qa1's- what's a few hundred more on this project
