275/60/15 drag radials (BFG), KYB shocks, 168k mile stock springs (for weight transfer yanno?), pinion snubber, GNX rear seat braces (i dont know if they did help or not, but the car feels alot stiffer!)
If you still have your front control arms connected instead of taking them off just unhook them and tilt them upwards your 60 should drop 1 more 10th if you havent already mine went from 1.9 with a new torque converter & front arms disconected to a 1.63 once and 1.67 twice. the rest was 1.7s....
