need street/track alignment specs for wcm s2k

[Bruce K]

I want to verify my file information regarding the correct street/track alignment specs for the wcm s2k. I have .1 degree toe-in; 5.5 to 6 degrees castor; and 1.5 degrees negative camber (radial tires all four corners). Any other alignment tips would be greatly appreciated. Thanks!

I can't attest to the correctness of my setup for any particular purpose, but here is what I use.

 

 

Front toe in 1/16"

 

caster 4 degrees

 

Camber ( front) -1/4 degree

 

Camber (rear) -1.0 degree

 

toe (rear) 0

These specs work for me but my S2K is a bit of a pig at well over 1600 pounds. Running 17" wheels, 8" front, 9" back. Could use a bit more negative camber if I was track only but this is a good track/street compromise. The shop that did my alignment has a lot of experience with Lotus cars and "one offs". RNR's car may be pretty close to this and he's fast on track.

Sorry Bruce for the late reply to your PM. That's a good starting point. Caster is probably the max you can get. It will keep the car very stable at high speed and on the road. Steering will be a bit heavier at low speed but not really a big difference. If you can get between 4.5-5.5 degrees you will be happy.

I know when we corner weight the car the drive is in it. am curious.. with the light weight of our cars (relatively speaking), should the driver be in the car for the alignment?

thanks for that extra info on the caster number. i have a front drive cadillac cts that i just required the alignment shop to set to less than minimum caster, so it wouldn't self-center so aggressively. i prefer lighter, more communicative steering, so i will use 5 or 5.5 degrees.
