I have 9x17 w/255/40s on front and 9.5x18 w/275/35s in the rear.

Now that the car has all of Jimlabs bushings in and is back on the ground...I am in extreme need for an alignment. I used to run the Pettit long course settings and loved them...good compromise for handling/wear. (This was on stock wheels though.)

The question is, do I set the front up per the 17" long course and the rear based on 18"?

How badly did I just screw up my handling with the 17/18" setup?? Not that it matters anytime soon! If its that bad...I'll get the 18s for the front to.

TIA

 

no problem w the mixed diameter... w jim's bushings you'll want to take into consideration you don't have alot of slop that it would have been smart to compensate for... so run about 1.2 degrees neg camber front and rear, less than an 1/8th toe in and about 29-30 front and 27-28 air pressure rear set cold. make sure when you set air pressure you have not driven the car.
it should be a nice setup.

Cool, thanks Howard!

 

Howard rules.

Say, how bout a few pictures of your car w/ that 17/18 setup?

 

I'm going to...but its filthy right now...so need to wash it up first. And Manny is going to get on me again about the damn center caps!
