Trans was built buy liberty gears here in MI. It's faceplated and has a viper mainshaft. All parts were heat treated and shot peened.
With it being faceplated the box is un-synchronized 1st thru 4th. It still needs you to clutch it but only enough to get it out of gear and then you slam it into the the next @ WOT. It's clunky and loud around town, but with some double clutching and practice most people wouldn't even notice.
The rear is a Midwest Chassis (MWC) fab 9" w/4.56 gears and a tru-trac diff, 31 spline axles. ABS still functions. It's got MWC's short torque arm, spoon's antiroll bar, umi lower control arms, and a 3.5" PST Aluminum driveshaft.
QA1 single adjustable coil overs out front and double adjustable out back.
100 shot it's been 130mph - 150shot, 132mph. Best et with the T56 is like a 10.6@131.
I've been fighting a traction issue this year with the new twin disc clutch. It hits the tires harder do to more mass and it's instant burnout if I go WOT on the 2-step and dump the clutch. I've tried everything shock settings, suspension mount points and tire pressure. I even put the 4.56 gears back in the thing from the 4.11's.
I think I found the issue - being the shocks don't have enough travel on extension.
