Here is one I dont know the answer to;

You have stock rims (16"x7"/+50mm Offset) on stock tyres (225/55/16) but the car has been lowered 1" front and 1.5" rear, how should the geometry now be set, use the standard factory settings at the new ride height or compensate for the difference in ride height or, jack the car up to the original ride height to have the factory setings applied before letting it back down to the modified height??

 

A good street performance setting would be 1.5 deg front, 1/16" toe in, 1 deg rear 1/16" toe in. Max caster up front I think it's 4 degress.

I'm sure you'll hear otherwise from others, but that's a good compromise for handling and minimal tire wear.

Cheers Todd, I presume mean I should apply these settings at the current ride height?

 

Yeah, at current ride height is where you should set things at.

If there are minor handling issues with oversteer or understeer, you can change the front to 1 deg negative or even the rear to 1.5 negative, or whatever combination to fix the problem.
