[QUOTE="sprint200, post: 9032165, member: 48265"] Like racebronco said, yes a splitter 6" off the ground WILL increase front downforce. If that's where your car is right now and you ADD a splitter with no other changes, you should have slightly less air going underneath and a LOT more downforce depending on the depth and shape of the splitter. Why else did the guys at SVT spend any time at all tweaking the shape of the KR splitter in order to [I]increase[/I] front downforce and balance the overall downforce of the car. Those cars sit ~6-1/4" off the ground just like mine did when stock. Currently my OE splitter is 4-1/2" off the ground with the Hoosier slicks and just under 5" off the ground with the OE street tires. And there is very clear evidence that even with the 550# springs up front, I am still managing to lightly scrape the splitter. Now maybe that's happening on the streets with all of the drainage swails and what-not; but I don't think I want the car any lower even if it was a dedicated track car. If you look at some of the other pictures on the Chicane 23 web site (a couple of good installation shots on an S197), you will see that their splitters don't end at the front fascia, but rather are a straight line across from wheel to wheel forming a tray. This should help in boxing in the radiator as well as help reduce some under hood pressure. The S197's have some plastic pieces that attach to the bottom of the fascia and the radiator support but they are not smooth and flat and do not extend from wheel well to wheel well. And remember Bruce's experience with TOO MUCH downforce in the front. If he was puckering from the oversteer, most of the rest of us would be backing it into the tire walls:lol: I already have throttle induced oversteer at will; and most likely will be playing with the settings on my rear sway bar and/or going to 600# springs if I add this piece.
