How Much Rear Wing Riser Height for APR GTC300 ??

Hi,

I've got an Evo VIII track car. I'm running it with suspension, engine and tranny mods. I have an APR front splitter and just got an APR GTC300 61" wing, because I need more rear downforce.

To be honest, at its 12" (or so) riser height it does not seem nearly high enough, and no where near the roof line.

What has been YOUR experience for recommended wing heights for the Evo for track use???

Thanks

there's no way in hell you need more downforce in rear ? tell me what's your car doing on the track ? and also why do you think you need more rear downforce ?

Even at the hight of that wing, downforce is still noticable, but I'm pretty sure that APR has extension that you can add to bring it higher. I don't think it's needs to go up higher, but you can do that if you have to

They have a "gt500" which is right at the roofline I think.

GTC300 and GTC500 are both the same riser height.

The car is getting loose on medium and high speed corners.
I can't take corners "fast", of course, it's 3250# w/o driver.

(Then again, I got used to tracking a Diasio this past season.)
