In comparing the Indexes, something really jumped out at me...
the 335i is F-Stock as opposed to our D-Stock 1.
If say the target is 55 RTP in open street tire, our 1's 60.6 second time is equal to a 3's 59.7. Sure the 1 is soft up front but is the geometry that much different for the class jump? In either case both go the STU, BSP route, and in the end you're basically going against your own class, but i'll definitely be open street tire stock for this year at the least.
Also sort of strange that the 128 and 135 stay the same class...
