my unstable 914.

A reprint:

I could use some input from those who spend some time at 100+
in their 914s. At my first ever track day I found the car really started moving around (I mean REALLY) at these speeds. The back end would just move over a foot or so in both directions

Toe? Aero? I'm clueless. My AX set-up slew em' in the twistys, but gave it back when I had to stop gassing it on the straights.

-2 camber at both ends, 1/16 toe in both ends, 5 deg caster at front, LE spoiler in front, nuthin' in the rear, big stickeys at both ends.

I didn't take the opportunity to walk out on the track at lunch time...maybe I shoulda.

The problems on the back straight were worse. There may have been ruts from the CART cars braking, but I didn't notice a lot of roughness at lower speeds. I also doubt I was accelerating where they were braking (IMG:style_emoticons/default/laugh.gif) The car does wander quite a bit on freeway ruts, but I can feel that thru the steering wheel...not so with this.

I'm thinking that my 4-5 year old plastic bushings (the squeaky SOBs) may be shot. The car was aligned this last spring, but AXing on these rough surfaces may have knocked it out. The HD Bilsteins may not up to the task of dealing with 200 lb springs.
Tire temps show I have too much negaitve camber in the rear.

Oh well, 2 more AXs and ulf goes up on blocks for rectal surgery. I detect the formation of a plan....
Some Mueller bearings, Koni sports with collars, and some more toe, me and my die grinder can get more front caster...may as well get another trunk lid to fool with also.

We here near PIR have lots of track days, the Lotus, Alfa, Shelby, Porsche, all have agreements for sharing.
I hear the Vipers get out there and don't use the chicane...more room for the Nitrous to kick in...I'll pass on that !
