Hey Ellis. When you say correct, do you mean the fact that the right side of the car seems to be higher than the left? If that is the case then I would say that it does not look correct. However this is an illusion from the camera. When a car launches hard the left front wheel should come off the ground first not the right. However, I have seen several pics from the track where it seems as if the right is higher than the left. I have seen this with both of my cars. I actually have a pic of my C4 where it appears that the right tire is off the ground and the left is not. We know that this can't happen. I have also seen this with Eric Fischer's Dad's C4. Eric do you remember me pointing this out to you awhile back. In any event it is an illusion and I am not sure why it happens. Maybe the photographer could answer that question.

Yes, Dave exactly..
I have sen where guys cars are purposely tilted to one side..
Another thing,,, Some guys use a slightly lower tire pressure on one side..
I am not sure what side, and want to know why, or what the results are..

this is drag racing, not circle track racing.Chrysler solved this problem back in the '60's by adding an extra leaf to the passenger rear spring, but of course since you have a monoleaf, that won't work.

IRS doesn't work the same as a solid axle. The car/suspension will torque rotate somewhat opposite to a solid axle. That said, it's hard to tell from a static pictire, but your car seems a little stiff in general. Not much lift or swat.

With a solid axle, the rear tries to twist, lifting the right tire into the body (compressing the spring) while the left side separates. This tends to pull the left ide of the car higher than the right.....and with a flexible chassis, you'll see cars with their left front wheel way off the ground while the right is much lower or still on the ground. With the IRS the rear housing tries to twist as well, but it is connected to the frame and unsprung. In this case the right side of the car will tend to lift more than the left, but the difference is much less pronounced because the rear housing is unsprung, the vette chasis is relatively stiff and uses an anti-sway bar in the rear.
Maybe Leo can jump in and explain this better than i just did.
