1.75, 6" lowering in the rear w/ DJM flip kit, Cal Tracs, M&H Racemaster 275/55-16 DR's. That was spraying a 100 shot about 10-15 out. 2.0 is my best on motor, have to learn how to drive a little better.

 

1.93 stock Z71 suspension in 4hi

 

1.83 60' with M/T 325/50/15 street radials. Stock suspension still on the truck with crappy 2.4X 1st gear ratio in the TH350 tranny. 3:73 rear.
It will get much better nexttime!

 

1.9 in 4WD, AT tires.

 

2.2 on stock generals aired down to 22 psi with stock g-80 and 3.73's . going back later this month see what the kumho 275's will do

 

Best 60 is 1.57 with big ole 295/20's, and just a hint of spin. It slowed the et down by almost 2 tenths.
Spinning awd (stock suspension gmc C3) with some much narrower tires netted me a 12.43 et, but the 60 went to 1.73.
I'm hoping that now with 4-18 inch nitto dr's that are as wide as the 20's, but 1 1/2" shorter and 12lbs lighter I'll get the best of both worlds if I can ever get back to the track when the weather is cool, and I don't blow the trans, the math tells me if I can hit a possible 1.55 60 ft, it should drop the et right down to the 12.00 mark.
