I meant that he has a LONG way to go IMO before that needs consideration , working the tyres to the best of their availablility is more to do with mechanical grip and spring control , sure a slippery shape helps but then the 3dr has that in its favour already .Time attack is all about a 1 lap , getting that right at the optimum time and temps is all about the tyre ,and not a very good one at that so go practice the set up to each circuit and optimisie what you have ,get it off those 18" rims for a start and drop the car over the wheels ,re-valveable dampers and optimise the geometry etc...
