Suspension help after whipple install

[db252]

I got the same result after adding the supercharger. Had plenty of suspension upgrades as well but at the time, and seems like you don’t have them either, and the answer was to change the control arm bushings out to bearings. If you still have bushings, the power you now have is flexing that rubber giving you immediate toe changes to the rear tire which acts like rear steering and not in a good way. I changed to bearings and it immediately corrected that issue. Traction of course is still a problem but rear steer is gone which acts just like oversteer.

Check your alignment (rear toe in particular). You need slight toe in on the rear to help keep it straight when you start to get wheelspin. Make sure you dont have too much rear camber either.

Go back to a stock rear swaybar to get a little grip back.

Adjust tire pressures and/or get newer stickier tires. Crappy or old tires are never going to allow anything to work.

Have your tuner revise your tune and go easy on the throttle response curves. Give the control back to the driver.

Install a rear lower control arm bearing (install is a PITA) and toe link bearing, which do help the powerslides become more controllable, even if they don’t really add more grip.
