Pretty rich actually very rich. 25* timing

I think we're having issue getting lined up straight any tips?

Looks like the car wants to pull left, except for that last video. one trick is to put an adjustable diagonal in the floor of the last bay (between midplate and rear axle). You can take that diagonal and by tightening or loosening, stop a car from pulling left or right.

Ooh that's a great idea. I was kinda thinking it was just my driving.
This car has several slips in the front section. I almost wonder if I should adjust the slips but idk what side to adjust.

slingshot383:
The slips just let the car think it is longer wheelbase than what it is, better weight transfer.  If it would have been moving right off the launch, I would suspect the wheelie bar of steering the car, the fact that it happens past the 60' mark usually means the rearend is driving the car that way.  One other thing you can do is swap sides with your slicks, if runout isn't equal that will drive the car also. If you find that is the problem, run the shorter slick 1 psi. higher. Or, pump it up to 40 psi and set it in the sun for an afternoon, that will make it grow some.

I checked roll out and it was 11/16 difference the taller tire being on the right side.
