Boxster Racers Spring Rate Changes - Experience

We run 1000/1200 on the CaymanSpec and it works great for Laguna Seca and AAA (smooth). Sucks at Buttonwillow (bumpy) and is OK at Willow Springs. Our issue is more likely with dampers than rates.

Unless you have all kinds of aero loads, I would tend to agree with Glen about the equal spring rates, front & rear. I used to run my 914 that way and it worked pretty well.
Can't imaging Buttonwillow being more bumpy than the old Summit Point paving & my RSA worked well with 1400+ lb springs, but you are right in that it was all about the shock adjustments.

Wheel rate my friend, wheel rate. 1400 lb springs on a 911 are going to end up with a different wheel rate than 1400 lb springs on a Boxster.

True, but not in the front. They are fairly similar there, but what I was more trying to illustrate was that his issue with the 1000 lb springs at Buttonwillow probably could be cured by proper shock adjustment (assuming that they are adjustable).

Box has basically 996 front suspension on all 4 corners. So I would put 4 996 Cup corners on the car with 4 equal Cup front /tender spring combos with 4 Cup front shocks. Very cheap and I bet it will work great anywhere. If You use the bilstiens You can always have them revalved and they are plentiful plus very cheap to rebuild,revalve....

Thanks for all the input. I have made my decision and feel confident that it will be light years better than the PSS9's. Now I wait and hope that FedEx delivers the goods on Friday so I can get it all back together.
