A few years back I was contracted to do some development work (suspension and drivetrain) for Tri-Point Enginnering / MazdaComp... and was lucky enough to get some
good seat time during development of TPE's multi/consecutive year championship winner (Jeff Altenburg). It was actually kind of unfair... we had all of the former Mazda IMSA crew working the project (engine and electronics). Well... maybe that... and our "open" budget.
The hands down top of the list items are: Penske's, a "tuned" MazdaComp limited slip diff and some transmission tweaks. Those alone are going to be the majority of 'reliability' items. The differential carrier (posi) is about as big as your fist... so remember that when you start throwing squirrels at it.
That little car is pretty bad ass when you get it set-up correctly.
There are a bunch of cheap and stupid simple tricks to give it an edge. But, since you are all going to set them up the same... I guess it wouldnt be fair to just tell you.
