Good read Harry and well done given the rest of the field,if i was in your position i would'nt do anything just yet other than getting in as much competition as possible,making a few small tweaks along the way to help the times drop a bit,we all know with a limited budget these things take ages to get to our liking.The split times will be interesting to compare with the others in the class,to see where the car needs more pace to have it closer to the pointy end.Don't drop your chin,you did a good job,and forget IPRA unless you win the pools,it's more than S/Sedan at our level
Cheers
