1975 chassis and I am converting the front struts to 1972 911T with housings,inserts,hubs and brakes. While I'm in there I'll do turbo tie rods,balljoints etc. I'm keeping the 914 A arms but I'm thinking of bumping up the torsion bars? Car will be street driver,autocross and maybe a DE or two each year. So what size torsion bars to go with? I see the difference between solid and hollow on this site is only about $30.00 or so, is the hollow worth it? The car currently does not have any sway bars should I consider at least a front bar? I kinda like the 911 under body sway bars as they are cheap and easy to install, I can weld the u-tabs on myself so is a 911 front sway bar O.K.? Or should I go "thru body"? I will probably do Elephant Racing poly bronze bushings also. Did I forget anything? Oh I will be running Fuchs in 16x7 + 16x8 with 205/55 + 245/45 tires under metal GT flares. Thanks guys
