Miatas are easy to drive loose. So why make one loose intentionally? My opinion on the matter is to make it tight so you can brake later and trail it in to rotate it. It really should be just a tad pushy so that you have to do that. Not bad pushy, mind you, but just a tad. I think data has shown these cars to be able to carry more corner speed this way than any other setup.

YMMV, however.

There's a lot more math involved than that sentence suggests.

http://www.fatcatmotorsports.com/FCM_MSDS_v7_1.xls is a good motion ratio / spring rate / sway bar calculator that would be a good start. IMHO, Kevin's front and rear rates aren't complementary, he either needs less front spring or more rear spring.

I run 1-1/8" front hollow with no rear bar and 375/250 front/rear spring rates. I did have Lee Grimes revalve the stock Konis to their RACE valving too (thanks to all involved with that). It's slightly pushy now, but I go slower when I loosen up the setups. I need to take lessons from Buckley and go ahead and put on the ginormous Suspension Techniques rear bar on it and stop being a wuss.

Hi Wes. Yes indeed there is ALWAYS more math behind that simple statement. The sheet you pointed to certainly has a wealth of information.

The bottom line for me is to set up the car in such a way that you, the driver, are comfortable with it. That will give you the confidence to drive it hard and get the most out of it.

I might get into your car and HATE the way it handles and be slow (I might be slow for other reasons too!). Everyone that drove my Civic on track got out and said something to the effect of "man that thing is loose". I never felt that way. If they owned it the would most likely make some changes to it. I was happy the way it was.
