Aero kits usually lower top speed, in this particular instance there is no way it will add 15mph.

+1
Every car I ever saw with a "full aero kit" was 15mph slower. YMMV

RE the OP: 135mph indicated in turn 1 at Auto Club Speedway. GPS data logger says 130.

How fast were you driving last night in the St. Louis area when you hit that poor young lady with your Porsche Boxster?
