What would you do?
Real situation. It's the night before you leave for a weekend track event. You've changed over to track pads, you adjust the suspension to track mode and you switched to your track wheel and tire set up yesterday. Your car was corner balanced by a race shop 2 years ago.
Today on the way to work you notice the driver's side rear tire rubbing over bumps and on your favorite on ramp at speed (never did that before you switched to Yokohama AD-08Rs, which run too darn big). Get home and measure the rear ride height bottom of rim to bottom of top part of fender arch. Passenger rear 23" even, driver's side rear (the side that rubs) 22 3/4". Considering that the car is/was corner balanced, but maybe after two years of daily driving it's settled a bit and the corner weights might not be what they used to be do you: 1) Raise both the left and right rear ride heights by 1/4" to "keep the balance?" or 2) Raise only the driver's side rear by 1/4" and now have the rears matched but also hopefully have less rubbing on the drivers side tire. I'll wait for a few responses and tell you what I did (probably wrong). |

That depends where it is rubbing. If it were the fender liner in an area that didn't matter I would trim the liner.
If it was hitting the painted fender then I would run a different set of wheels. I would not be inclined to mess with he ride height.

If its rubbing on metal or bodywork, I'd raise all 4 corners the same amount.
