I know there has been chat on here about stagger I'm trying to go a little more aggressive. I have a 2008 Panel. Has anyone done an 18 up front and a 20 on the back. I'm also looking to lower it as much as possible. I know it's a little out of the norm but I like being a little different. My other project is a panel Astro Running 29/1850 Mickey Thompson pro streets on the back plus it sets on the rockers. I would like to not go that radical with the HHR but I would like it to be different.

 

You can't stagger very much or the abs will get screwed up because the 4 wheel hub speed sensors won't match their rotation values, front to back.
Besides. You can't really fit a much bigger tire in the rear wheel well. No clearance.

Stagger is left side to right side tire size difference, rack is front to back tire size difference, just clarifying some old hot rod and racing terms, now if you go with 18 inch wheels up front and 20 inch out back then you should be able to match the tire diameter by size, however you may still have clearance issues at either end

 

Yeah, the key is keeping the outer tire diameter close to avoid ABS or Speed Sensor issues.

If you are looking for rake, where the rear is actually higher than the front, I think you are going to need another trick or two - likely involving spring heights or maybe lifting the rear a bit.

 

Okay thanks
