The Porsche is the same 245/275 but they carry their weight on the rear.
Everything else in the series is 275 F/R
That being said...the car is very well balanced and it's not like we are wearing out the front tires..but it would help under braking.
I'd rather they give us a weight break.
Tires are tires...the only 4 things that touch the road so they are a pretty big deal...
For tracking...get what you can afford...because you will use them.
