I want to get a tune for my vantage. I want it to be able to be at 550pp at 569hp. I need a track tune for it and I am working on a tune for one now. If you have one leave a message and I will try it out.
You shouldn't have a problem running either tire choice on it. Maybe trying adding 0.3 camber to front/ rear and 0.5 to the spring rate front/ rear to cope with the better grip.
