Raced my new T4 last night, crazy grip right from kit settings, spent quite a few heats just trying to dial out grip so it could turn better, then just did a tweak to shocks up front to get a little more corner entry bite, every bit as fast as the old car I had, just now need to work on some mid corner speed, it feels a little slow around mid turn, may play with roll centers to get some more of that.
Looking at those pics earlier, is it just me or do the diff pulleys look a lot bigger?
