Guys need some help ......just looking at some pics of my car at track last weekend sixty foot was 1.5's but it never hooked hard IMO hard to beleive the sixty foot was actually 1.5's cause was spinning after launch Manual Trans car 5k launch ET drags still sidewall 28x 10.5 .front susp working decent not a serious race car so only 4 3/4 " front travel but shock settings seem to be close front settles slowly front tires appear to be totally unloaded just starting to lean out a top .......it appears rear susp is not planting tires into pavement the body squats a bit ..rear shocks on full stiff HRP anti roll bar control arms in stock location .no wheel hop car goes straight ....... where should I start ?? is this an instant center thing do I need to move the IC back by using something like the UMI relocation brackets ??? Thanks Bill

any video?

yes, you need the re-location brackets or no-hop bars like Edelbrock. Both work the same way, use the torque reaction of the rear axle to push the body up and axle down.

if it's squatting at all that's the opposite of the desired deal. anything pulling down on the body is pulling up on the axle.

To do any track type suspension tuning I feel, from past experience and expense, you'll need a double adjustable shock. Preferably on both the front and rear but at least on the rear.
And I've also found that the QA-1's simply do not have enough range of adjustment for various track and weather conditions.
The Alston Vari-shock worked very well for me. Even better than the Koni's.
