Front End Floating at High Speed
Re: Front End Floating at High Speed Koni double adjustables would be the best fix along with a spring kit. Here is where your problem is though. At those speeds you are pushing a ton of air under the nose of your car and it has no place to go. this is what causes the "light" feeling. A hood with extractors on it as well as an air dam will eleviate this problem.

Re: Front End Floating at High Speed NattaSS is correct..
But short of air dams & air extractors.... A good set of shocks & springs will do wonders.
My preference is Bilstein springs (1.5" lower) & Bilstein shocks. Dead solid at 140mph plus.
Here's a shot of the WS6 with the Bilstein suspension.

Re: Front End Floating at High Speed If you want some more info email me. I run in open road racing events at VERY high speeds, so I have done alot of research on areodynamics on our cars. I am preppping my car to run at 200mph for an extended period of time, while cruising at 170+. I might beable to give you some ideas for high speed stability.

Re: Front End Floating at High Speed Thanks guys. I'm not planning on running those kind of speeds. I hit about 145 the other day on an open empty road with my brother and we both noticed the front end floating? Looks like springs and shocks after I stiffin the chassis up.

Re: Front End Floating at High Speed Don't forget, when you get those springs and shocks on, have a performance alignment done to your car. Absolutely do NOT let anyone put factory alignment specs on your car.
0 degree's toe in
.5 to 1.5 degree's negative camber
4.5 degree's positive caster.
This will do wonders for high speed road feel.

Re: Front End Floating at High Speed No, they don't. I'm using these very same specs and have run the Silver State once ( at 165 mph ) with NataSS. I've gone threw 2 racing schools + 3 lapping days. I've got 26,350 miles on these tires which are the original F1's and while very thin these days, are worn perfectly even across the tread width. I've been told that you can up the negative camber to -1 to -1.5 degrees without adversely affecting tire wear.I don't know, I haven't done it personally. When I get my new KD's I'm going to find out though ! <img border="0" title="" alt="[Smile]" src="images/icons/smile.gif" />
Re: Front End Floating at High Speed I'm running 4.5 degrees of castor, 1/32 inch of total toe out and 1.3 degrees of negative camber. My tires look real good so far....but when I ran similar specs on my 3rd gen Formula, I wore the inside edges of the tires faster than the outside edges...but still had 15,000 miles on my Firehawk SVX tires and had some tread left....Happy corner carving.
Re: Front End Floating at High Speed I also have a question,but mines the other end. I have a 99'Z28 1LE. The car has the Koni yellows on it. At around and above 148mph my nose is glued to the ground, but *** end feels high. Do I need an under the car spoiler? Any recommendations. The car is set at it's factory setting, suspension wise.
Re: Front End Floating at High Speed Sawed off,
YOu may try lowering it (about 1.3-1.6 inches) or an airdam across the front (and side skirts down the sides). A Camaro is shaped alot like an airplane wing and at that speed, the air can't tell much difference between the two. In order to make lift, you need high pressure air under the car and low pressure air over the car. There is not much we can do about the low pressure air on top of the car (large spoilers or "wings" maybe), or we can get rid of the hith pressure air under the car (air dams, side skirts and lowering). If you can get air out from under teh car, it will be more stable and stick much better at speed. This is why the NASCAR boys used to have those spectacular wrecks when they spun at speed, the air got under the car (no chin spoiler in the rear) and once we had high pressure air under the car (high pressure air is air that is stationary, or moving over a flat surface...like the ground) it would fly....
Good luck.
