In what TT class? Wouldn't that just fit into the aero category? Sorry only really know rules in TT 1-3, I assume all aero is covered under the aero points in tt3 and unlimited 1&2?


My splitter looks pretty similiarly setup but I am able to get the car to rotate in high speed turns with lifting a little and am not getting snap oversteer.

I'll check the pitch and post when I can of splitter. I know my wing is pitched a 3 degrees.

I agree with sealing the gap between the splitter and bumper. Also, double check the angle of attack with a level.

I sealed mine with RV weather stripping. This pic was my first attempt at sealing it. It's much cleaner now, but I don't have any pics. This pic, the splitter was at 0 degrees (relative to ground plane) angle of attack.

You are in a numbered TT class. The lettered TT classes take points on each aero mod whereas you only take a modification factor added to your ratio.

Dan, thats too much splitter. I did mine that size (about 4-4.5 in.) and cut it back to 3"
You have the gtc200 rear wing which is not giving you enough downforce at higher speeds to match the new front downforce.
I tried increasing my rear wing angle and it just causes to much drag, so doing a smaller splitter balanced it out.
The bigger the front splitter, the bigger the wing needs to be to equal the planes.

Not always.

brian my thought is the GTC-200 is just draggy fullstop and once I hit 6th gear over 120mph the car doesn't accelerate much whatever so might as well try and find some downforce and use the beter midrange on the 2.2
he driver could use some help to and aero should make it more stable and not do this to much right!:

Since that crash we could only get the back down to 1/8th rear toe-in (with slightly more on the left rear ) +we raised it up
so I am thinking as well as catching some funny wind off the front when I lift it might just have more bumpsteer?

I'm thinking maybe turning up the rebound on the shocks both ends might help stabilise the car in general?

Ya, a 2D wing is on my list. Thats the best way to get the rear downforce with less drag (like Voltex type7, apr gtc 250, etc.)
But those are $$$, and too many other cost right now.
