Thanks to all the imput guys. Its not about strategy from my point of view. I am actually talking about a few of them namely all the guys that are on top of their class i.e. the leaders all have that in common, the free drivetrain, apart from their overall experience in years and me, a rookie relatively speaking, I joined the club in December last year, participated in 5 races since then, best position, 4th A group. Best average time achieved over race distance 15.830 seconds versus their best of 14.900, I say I have a fare way to go. Overall points standings at the moment 3rd out of 19 guys in total. The advice I've been getting was very genuine and made sense overall, My first 2 races averages were about 17.200 sec's and since then improved to the 15.800 mark, I think a lot of thats got to do with the change from the evo 4 ms to the trf msx....and pure track running time. Best lap 14.930, lap record 13.900, currently fast guys getting 14.300, me 15.100. My thinking is to have all the right equip in place, eliminate all unknown variables, then take it to the track. But getting imput from you guys out there is very valuable and comforting. Those ceramic bearings and diff balls are on the way....It cost a bit but eliminates a variable. Thank you so much for the imput!.
