Ultimate Boxster S HPDE Project

[Tabbasco]

First...My Buddy and I are racers and hpde instructors. "ET" races a 996, I race WRL, Chump, LeMons in a 2nd Gen MR2...this car will have data and we will use it to hone quali skills.

So great suggestions on the exhaust, we prolly won't pull the clutch/flywheel till we break something. It makes sense to replace the flywheel and replace the IMS bearing when the clutch comes due.

Where is a good source for fg fenders, hood and trunk?

The car weighed 2850ish originally, We will post weights at every major mod interval. The doors are gutted. We came up with a trick mod for the glass...and we left the door bars in for protection, no cage. We plan on welding in a taller cross cockpit roll hoop.

Decided against the lexan windshield...decided to keep AC & Heat...Texas can be brutally hot and cold for transit to track. Was hoping to buy fg bumpers but those are no longer in production.

Why put vents to the rear bumper??

Perhaps to help the trapped air to exit without additional turbulence, and help to cool the engine compartment as well..?
Curios as well

Cools the transaxle better since more air is flowing over it when you have these rear cutouts.

one of the things i've noticed - look above the transmission - that's a long flat surface that will collect air. no vents and you have a parachute. vent in the proper place and you have a rear diffuser, posing as a vent, in a class that doesn't allow rear diffusers ...

sort of like the vent the front fender liner trick - tell everyone that it is to get more airflow onto the front brakes (brake cooling allowed) but really it is to redirect air that would otherwise be going under the car and creating lift.
