Looks great. Can we get some detailed pics of the installed system?

Very cool mod. Can you still run 15" wheels, or are you committed to larger sizes now?

with this i believe you have to run atleast a 16". If you have steel wheels, you could take off a little bit of caliper material and potentially run 15's. I had a pair of slicks with the 5x5.5 pattern a while back and my friend who has a 02 dodge ram wanted to play... almost fit with no modification... he didnt want to mess with the caliper so we stopped there. I can take some pictures tomarow. I wouldnt mind starting a second set of brackets to use the LS1 rotors and calipers (so you could run 15" wheels with internal ebrake, but I'm going to wait till someone lets me borrow a rear end from our trucks. I dont want to keep pulling the rear end apart to test fit.
Iif anyone in houston willing to let me borrow a rear end for a few months, I definatly could make some progress. I dont want to purchase another rear end just for mock up purposes ya know...

You can really see the caliper in this shot becuase I'm running a 1.5" wheel spacer to give me the stance I want. The wheel offsets offered wasnt enough for me, but the spacer makes it workout perfectly.

Finally got some numbers... with hp tuners hooked up to the truck, and scanning the run, Ive got some stoping numbers..
60-0 = 5.249
50-0 = 4.540
45-0 = 3.562
35-0 = 3.245

These were calculated from the time bar on the bottom oh HPtuners. The front wheels definatly locked, I believe the rears didnt... but not sure. some not sure which when the truck slid, at lower speeds, I let up and re applied. These numbers are off of the VSS rather than distance.... which will be my next stage... I will have some cones at a certian mark and go at various speeds and record the distance traveled. I think that might be more accurate. The VSS would read 0mph if the trucks wheels are locked up... either way... heres some numbers fresh off the scanner...
