If you are heading out on track i'd suggest what I posted earlier as a great starting point and without going aftermarket parts worked very well for me. Aside from brake pads I can't thinking of any deficiencies in the stock car!

I kept suspension in standard road setting also and didn’t go to the firmer setting for Bathurst (and also Sandown) but for a GP circuit like Philip Island I have been putting it in track firmness.

Does anyone feel like the soft suspension setting doesn’t have enough rebound? I feel like I’m in a bouncy house in the soft setting and have taken to keeping it in firm setting all the time on the street.

Factory is fine for the street. On track you need the mechanical grip. Rebound less important than grip. My view only, others may differ.

Again, track only comments.

Max rear camber with factory length arms is 1.8 ish.

If you want more you need the longer control arm.

WP, steel brakes, LWB's, base radio, sport chrono , extinguisher, no lift.

I also thought it was bit heavy. Mag wheels and PCCBs are about 60 lbs I think. They must left a few bolts out of yours...

Steve Sutcliffe gives a few pointers on setup in his EVO lap time. He says firm suspension setting is best with ESC and TC switched off.
He also makes some comments about having the support crew set up the front end to be a bit pointier, altho doesn't say exactly what they did. He has probably either gone harder on the rear swaybar, or given it some toe out at the front.

I’ve been playing with rake a bit to make the front end a bit pointier. Might be what he means. I’ve got 10mm of rake dialled in right now. I’ve only tested it in the wet on track though, will report back after a dry session.
