99' Hard S Spring Length

[general default]

I was hoping one of you guys with a repair manual could look up what the free spring length minimum is for the front and rear suspension.

I have always heard it was in the manual but I have never seen it published or quoted. What are the magic numbers?

I did find JRW's post on the board for 2001 Hard S springs.

Minimum Free lengths for 2001 Hard S Springs:
Front - 310.5 mm
Rear - 328.5 mm

These numbers came from Brian also.

In this case Brian refers to.

we see spring lengths vary up to just over .25"

alot of guys running SSB will buy 3 or 4 sets of springs to get the set up they like the most, since they are supposed to use only OE stuff

General,

I have a service manual for my car and I could not find the lengths in the manual either.

I thought someone posted the free lengths for the '99s and '00s in that same post.

I'll have to look, I do have a Miata spring thread bookmarked.

I do know that front springs just above the minimum and the club sport Bilsteins give me about a 12.625 inch dimension from wheel center to fender lip.

Thanks for the info about the spring variances. That is what I really wanted to know. If I was to buy 4 sets of springs my luck they would all be longer than the ones I have. :P

From my searching on the subject it appears the manual does not state a minimum length of the spring on a '99. If a spring is protested in "Solo2" the spring(s) in question are compared to a new spring. (To bad if your stock spring is shorter than the reference spring). That is why I think there is a "real number" to compare to now.

But it would still be nice to know what that length is in case you were looking at a used set of springs. It would be good to know that they had not gone below the minimum before you installed them.

Since the SSB guys know there is a variance of .25 inches I guess they know what the minimum length is.

JRW thanks for the ride height numbers. Seems like mine was 13. I will have to go check again.

Sounds like the General is considering some changes this off season as well.

I looked at the info I had bookmarked and it was ride height info.

Email Mazda motorsports, I'm sure they know.

I'm looking for some hard-s fronts (for an 01) in case anyone runs across any.
