Hi Matt,

First question that comes to mind is how much space is between the top of the axle tube and the rear subframe (if you can call that piece of tin a subframe ;-}) when the rear suspension bottoms out?

Just had a brain fart... What functions as a bump stop on coupes? I'm a sedan guy and the bump stops on the sedans are part of the rear shocks.

Is is possible to relocate the bump stops to gain suspension travel on coupes?

On sedans I have relocated the top shock mount straight up to get more usefull suspension travel. On my current car I plan on having the rear springs de-arched to be flat when loaded, increase the length of the rear shackles to set the springs parallel to the ground, then use lowering blocks to set the ride height. The lowering blocks will have shock mounts built into them so I won't be loosing so much of the suspension travel. You do have to be carefull to make sure the bump stops hit before the axle hits the underside of the body works though.

I have not found lowering blocks to be detrimental to the car's handling. Last race car had de-arched springs and 2" lowering blocks. We got several top time of days the last year that we autocrossed the car.
