I'll check out Lummus Racing, but you have the right idea I had thought of going with a four link with coil overs from Summit racing with modified diagonal arms and lose the torsion bars, spring plates, etc? I going to tub the back and run 17x8 rims and 245 to 255 tires? I 'm also going to run a turbo 914 or older 911 Porsche motor!
