Car Pulls Right During Wheelie Hey guys, took my Ultra4 car back to the track this weekend. With some slicks on the rear, running in 2wd the car pulled the front wheels, which is awesome, BUT in 2 of my 3 runs it drove hard right on the launch. What do you guys think would cause this? Could it be that 1 tire wasn't hooking as well due to poor placement on the track, or do you think it's definitely suspension related? My suspension has a lot of travel (~20") being setup for jumps not drag racing, which probably doesn't help...
You can see video of my clean launch in my post in drag race results I'll post video of the bad launches later.

Have you corner weighted the car at all? Might have more bias toward one side. I'm sure adjusting the length of the upper 4 link bars will change how it launches and reacts driveline torque. I really don't know exactly how to solve the issue but that's the likely path you'll need to investigate.

I don't think its frame flex, since this is a tube chassis and the entire structure is VERY rigid.
I have not checked corner weights, probably a good idea. I'll see if I can track down some scales. I have a double triangulated 4 link, so any adjustment affects the overall axle position and angle. What do you have in mind?
I've also wondered if the poly bushings at the front of the rear trailing arms could be too soft allow it to misalign under load.
