the dart sets 26 1/2" to the top of the wheel lip now,165R15,headers yes,I'd like to get it down to about 25" or so to the wheel lip,the k member is a moot point due to the 8 qt oil pan, and finally the t-bars seem to measure .900 . When I tubbed the car we set the rear end of the car down a little, now I have the torsion bars backed all the way out and adjusted the coil-over up in the back. I can actually set the car lower in the front with the torsion bars but it's not a very good feeling approaching a curve at any moderate speed.My plan is to use the dropped spindles to lower it and put more bar adjustment back in it to make the ride quality go back towrds stock if not better.
