Nothing against guys that run a lot of rear rake to their cars. This isn't about criticizing people rides.

But this is more of a reference thread. So people need to know the backspacing, rim specs, tire size, rear springs, air shock or not, distance from spring to tire, distance from tire to inside of top fender lip, and rear chassis height.

That will help people reading this determine if the info is valid for thier particular car, the way they want to build it.
