Just got the car back from Award. Had the gearbox reco'd and replaced all the synchros, modded the transfer case and shimmed the rear diff with Nismo plates.
Diff feels super aggressive and awesome just putting it on the trailer, should make a big difference. Here she is hanging out the front of Award. These guys have done a really great job at an awesome price. Terry knows about GTR diffs and gearboxes, I wouldn't take it anywhere else.
