Mike,

Can you start a somewhat sophisticated discussion of the ramifications of these two basic options and why some Cup cars go with more rear spring, and others go with more front spring? I know the basics, but I'm looking for more. :)

Don't want to bother, its is way beyond most peoples understanding and takes to long to type. I sugggest reading Race Car Vechicle Dynamics by Milliiken and Mikkiken as a starting point, bone up on your math and study the excell spread sheet I gave you. I gave you the easy answer for it already.

Or buy my book when it comes out.

BTW as I asked you, don't circulate that spreadsheet, its my classified material.

How often is increasing/decreasing rear or front spring rate part of your race prep? Does front vs rear spring rate change from track to track or does it stay constant to address vehicle issues?

I haven't circulated it, bud. Ok, offline conversation some other time.

Short answer---no. But for $19.95.....

generaly once the right set up is found, the sway bars are the main change from track to track.

Cool, that's exactly what I was looking for. I'm setting up for summer season and I was wondering if I should buy a different rate spring set up for different tracks. Mid-Ohio, Nelson Ledges, and Putnam Park are different, so I wasn't sure how different my set-ups would need to be.

I'll add to what Mike said... a little bit...
He's right though about things taking way too many words to explain... just go read some books. Lots of books...

People come to different spring rate setups due to many different variables. There are many many many variables that effect suspension setup. Variables beyond dampers and sway bars. The way your cage is welded effects things, the way your chassis was welded in the factory, the height of the cg, the roll centers of the front and rear suspension, etc...

In short corner weighting your car and thinking about ride frequencies can give you some clue as to what spring rates to try at either end.

I run different spring rates and ride heights for each different track. This decision is usually based on the track surface quality more than anything else... - GA
