Matt Andrews, last time I checked he was trying to sell it.

Mind posting up the rain pictures?

Had some spare time, so made up some aero to go with the new GTC 200 wing, copied a few ideas seen on this post. Ran the car last week at the track (on crappy Tyres), made the car so stable. Hard to say how much faster it was, the temp on the day was 100+ degrees, I only have 68 degree days to compare it too, most of the cars were running 2-3 seconds a lap slower then normal. I managed a time within .3 of my previous P.B. track is 2.2 km long. Will be fitting some 15x9's with semi slicks for the next session in two weeks. I know it looks a bit goofy sitting that high off the ground, but we have some rough tracks here, and every time I have lowered it , it is not as nice to drive and no faster

Wow, that is an extensive underbody aero treatment. The brace connecting the front and rear subframes is also of complex construction. You certainly have been busy. I wouldn't mind seeing pics and videos of some of your racing from NSW if you get a chance.

My car's aero equipment wants to be just like your car's aero equipment when it grows up. Nice work.

Wow, that under tray is perfect. Have you had any problem with engine, trans, diff temps?

yeah, love the tray. diff. looks like it might be suffocated, maybe throw a temp sticker on there, or use a laser temp gun to chaeck after a track session.

sorry I didn't buy them from the photographer, the pics I posted my brother in law took with my camera.

Brettauto 02-08-2011 05:07 PM

I will get some temp sensors happening for the diff and gearbox , engine oil and water temps were a fraction cooler even with the extreme temps on the day.
This is some race footage at Bathurst, not to many races held here as it is a public road, but it is the Holly place of Australian Motor sport. http://www.youtube.com/watch?v=UrPtUYeng0U It's not me in the car , but someone with much greater testicular fortitude, It's a demaning 3.9 mile circuit, with Conrod Straight 1.2miles long, off camber corners, 1 in 6 gradients, and a few blind bends. There is only about 4 endurance races there a year, so it takes some time to really know the track.



EDIT: only copy what's after the "=" in the youtube link for our YT embedding feature, kthxbye.

Holy crap. That footage was awesome.

ZX-Tex 02-08-2011 07:35 PM

Amazing driving. Seriously.

Is that under tray attached via po rivits or dzeus screws? Also what material is it constructed with? Looks fantastic. Perhaps a few naca ducts will help ensure temps stay down on your diff and transmission with a few openings in the bumper for the hot air to exhaust from.

jacob300zx 02-09-2011 01:17 PM

That is one of my favorite videos of Bathurst. Found it like 4-5 years ago and then lost the link. Can you explain any of your under aero? It looks like your center section is lower than the rest of the car due to the bracing? It also looks like center exhaust? How steep is that angle from the piece near the diff to the diffuser?
