60-0 Braking w/LS1 discs front & rear

[Six-is-Enough]

Finally got around to testing the LS1 rear disc conversion. To refresh everyone refer to this post: http://www.syty.net/forums/showthread.php?t=48364

5 stops back to back. Best stop was 127.9 ft (2nd)with a 135.4 avg and a 140.1 (5th)worst. The pads and discs were cheap ones from O'riellys. With a more aggresive pad(s) I am sure some one could get into the 110 range.

Did a couple of boost launches too. The rear discs held 18 -20 psi with no problem!

Also noticed the rear brakes were much LESS likely to lock up than the drums. I am still using the stock porpotioing valve.

All in all the ABS delete was the best mod for my Sy!!!:2cents:

Thanks for all the great info, Jeremy... has given me the confidence I needed to do an ABS delete system and brake upgrade on my Sy.

are you using a gtech for the measurements? if so, i'll make some stops with the Z51's for comparison.

Stoptech ST40s in the front with Z51s in the rear using EBC Yellow stuff pads, Bridgestone RE-01R tires and ABS off
60-0 = 104'

5 feet more than an Porsche 997 Turbo :tup:

How much boost can you hold before your truck starts to push? Mine starts pushing at about 1-2 psi now with all stock stuff.
