FC Center of gravity

I corner balanced my car this week.

CG height = 19.2" (measured with rear 4" off the ground. I need to check the +/-, since this isn't very high)
2500#
52% front
51% left

My car is somewhat lightened, but I believe most of the weigh reduction happened near or below the CG, so it probably didn't help in that regard. In summary: LS1+T56, single 3.5"exhaust, no interior aside from dash, gutted doors, alum hood, no headlights or bumpers, still have HVAC with heater.

My ride height with 25" tires Probably not much lower than stock unfortunately. That damn frame rail over the front tire ruins the fun.

i actually got rid of that hood scoop. the vents didn't flow enough for my liking (had cooling issues with my tilted radiator.

new vents work much better :)

Even if you're not happy with the CG Josh, the turn-in on that car is nothing short of amazing.
When you get the back to stick as well as the front, you will need to beef up your neck muscles for the sudden transitions.

we pulled the aero off on sunday afternoon, and the car was actually balanced pretty well. grip was worse, but much more balanced. i do believe the splitter is doing more than the wing- big wing time!

i also noticed that the endplates have a huge affect on stability when sliding, even at low slip angles. the car was way snappier without them.

If you are not already in the "big wing time" zone, then I don't know what is! Lol
Have you though about trimming down the splitter to balance the car?

I would rather add more wing than take away splitter. I ordered foam cores last week, so ill be putting together a dual element soon.

*like*

I'm not really surprised its not balancing out the splitter. It doesn't look like its really designed for low speed at all. Are you making the same wing I am? I still haven't even started yet... It got put on the back burner when I blew up my engine.
