The biggest front bar I've found is a 7/8" I'm not sure if there is anything larger. I have an 18mm rear 944 bar to go in but I didn't want to add it until the springs were close to final. I honestly didn't expect the rears to bottom out because the general consensus was the rear springs were much to stiff. Looking at the pics I thought even the fronts were overkill but they're a bit too soft as well.

Right now the springs are 300# front and 550# rear and I think I might add 50% to that and run 450# front and slightly more 900# rear. I talked to a porsche racer at a track day and his car weighed in at 2200# and he was using 1000# front and 1350# rear! The same porsche was also on 17x11 front and 17x13 rear wheels w/ slicks.

The rear shocks are QA1 single adjustables, which I'll swap out for double adjustables, and put the singles on the street bug. I'll have to find some snubbers that fit in the shocks to hopefully prevent them from bottoming out.
