Default big air racers, got a question...

What is causing the front end to lift so bad? Was it too loose in the front? Too soft in the rear? Combination of a few things? I've seen the Colonel and George C. lift about four feet or more in the air, but later "tune the suspension out" so it wouldn't do that. What did they change to keep the front end down?
Thanks.

Adjustable front shocks and/or adjust ride height are the easiest way to control front end lift.

My front suspension was set all the way to supersoft while trying to make up for a track that wasn't hooking so well. Next thing I know I'm countin' stars. I don't know that I ever "tuned it out" though. I stiffened it up just a bit and spun enough not to get verticle. Of course the 60 ft time wasn't as good as it could have been so that's why I say I never actually tuned it out.

The wheelie bars will be installed next time I get some air. <img border="0" alt="[burn out]" title="" src="graemlins/gr_burnout.gif" />

I've been playing with the torque arm settings a bit to try and settle my car down, as well as front/rear shock settings.

I'll also be doing some experimenting with ride height when my motor goes back in...

Light front ends + excellent chassis setups + big converters = wheelstand.

I did about two feet at NPR with the car shutting off I had the rear shocks really loose because up here I have to run them 3 or 4 to hook.

We have used double adjustable shocks, front travel limiters, adjustable IC torque arms, and movable ballast to control weight transfer. In addition to these tuning aides, we have found rear ride height to have a profound effect on wheel stands. As a rule, the higher the horsepower, the lower we attempt to set the rear ride height.

Hope this helps.

Default Re: big air racers, got a question...

i set my hals to soft all the way around- to make up for my lack of a real tire (16" et street) and i cant catch air. if i do, its very minimal. i cut mid 1.5 60's too, what gives. my car squats big time in the rear. maybe my frontend is too heavy.

i want cool pictures racing!

Lighten the front end up by a couple hundred lbs. Then pull some 1.3s. You'll catch PLENTY of air! <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
