I was screwing around today. I began replacing Philips with hex screws. It's so satisfying to have a good driver (MIP) and nice steel screws. Though without this experience, using the Philips head screws weren't terrible as long as you had a nice screwdriver.
The Xv-01 TC-T is still ripping. I traction rolled it a couple times today whilst making rubber screeching sounds. I may start fitting the Blitzer body if I finish with the the main screws. I don't really want to tear into the diffs and transmission since everything is running so smooth right now.
