Just read this whole thread, awesome! I too a newbie to vta let alone on road racing. I picked up a ta05 last winter and I am also now getting her ready for the upcoming season. Here is where I'm running into a wall with her( she be a version 1), gearing. I'm looking to get a 3.66 fdr , mine came with a 48p 70t pinion already in place, now if I understand what I have read 70 divided by 43( pinion) times 2.25 (tdr) gets my 3.66 fdr. It's the 43t pinion that's driving me nutty , that's one big pinion! Advice anyone? If it matters I'm trying to keep the car multi functional this winter, one place is vta 25.5 the other place is gt class 21.5 , 3.66 is right in the middle for what I'm being told for fdr for both places.
