Default Building boost, suspension ride up (vid)

Seems that when I try to build boost at the track...or anywhere else, the suspension rides up as the motor gets more load on it. Right now I have the lca set to the top of the adjustment, question is... would lowering the lca help the ride up situation along with helping traction?

My iroc would do that so quickly when I went up on the converter that it would actually pull the back tires up, I had a short tq arm. I fixed it with a set of double adjustable shocks, or maybe I should say I controlled it

So just the shock change tamed it? Same torque arm?

Yes, I had Lakewood 50/50 before, went to Viking d/a and I can completely stop the rise if I want to now.

Looks pretty normal to me. The front and rear of my cars raise up under load until the suspension settles back down.

So your trying to fix the rise that happens when doing a half *** stall/burnout???
Do you want the car to hook like a bitch or so you want flat easy burnouts for your friends to see? :-)
If you want it to hook then you need to not worry about that rise. Its supposed to do that. Your just loading against the brakes. That will drive the tires into the ground on launch and get good hook.

No rise, hooks fairly well (see vid). It's definitely not the end of the world, just wanted to see if it could be quelled and maybe increase traction by changing lca location.

If it was doing that when you are launching it would be called anti-squat. Anti squat pushes your axle into the ground giving you more traction.

I do, but I'm saving my pennies for a rear end. Still on the 10 bolt, so I've yet to use it....other than when I'm in reverse.

I believe once you're using the t brake, the rear won't lift since the suspension isnt loaded and from what I've read drives the tires down harder to give you a better launch. Thx for the cam info too

Normally you do get better traction with the lower hole in the lower control arms, you might try experimenting with it. Bob

Mine does the same thing. Skip to the 30 second mark.


No transbrake here and that was a 1.38 60'.
