Thanks Z-Dreamer, I was going to go progressive springs all around too. When I bought my coilovers for the front from Ground Control, I talked to the guy for a bit, and he said not too. That they didn't work well because the way he discribed it,... soft, hard ,soft, hard,hard. What he meant was you'll be driving along, and it feels nice and cushy, and you hit a dip or bump, and bam the springs get rock hard, and shutters through the car.He said to use regular rated springs.With 295-15-50s on 10" rims I think I narrowed the 12 bolt to 45".I using rear disc from a 79 Trans Am. Front disc are stock Datsun rotors custom mated to chevy drum hubs, and Toyota 4 piston calipers. One day I try to get more pics on there. I'm planning to put on a short video of my engine on the Dyno!(EFI 327- 435hp, 493 ft lbs tq)
