Spec Miata Suspension kit for $600 - Should I buy it?
 

Thanks for having the time to look at my post,

As the title says, I've recently stumbled into a Spec Miata Suspension kit for $600. I have a stock 92' Miata that I'm building for autocross events and daily driving. This SM kit has only been used in two racing events and includes 4 Bilstein shocks, 4 Eibach Springs, 4 Coil Over Kits, 2 Eibach Sway Bars and FatCat Spacers.

This kit was installed in a 1995 R package Miata. Do you guys know if it would it fit my 92'?

I've read multiple reviews on this suspension kit, and most people do not like them as they say that the springs are too stiff. Is it a good idea to buy them, and simply obtain new springs with a lower rate?


Thanks,

Angel

I think that's a good deal. You may actually need stiffer springs for the rear 400 or 450 lbs instead of 350 lbs depending on how you set up the car. Also I recommend buying adjustable sway bar ends because the 94-97 front sway arms are a little shorter or longer (don't remember) than the 90-93.

I'll look into those adjustable sway bar ends. I was recommended to remove the rear sway bar to prevent over steer and get softer springs all around.

Do you know if I can just change the springs without affecting the handling characteristics of the Bilstein shocks?

Thanks for your input.

If you want the car to ride like garbage, SM shocks are perfect.

What's your $600 suspension recommendation then

At that price, I don't think you can beat an Bilstein/eBay setup.

Isn't that an SM setup? Or are the SM springs super stiff?

I'm afraid you might be right about this. The Bilstein/eBay setup looks pretty good; but, the Spec Miata suspension kit also has a great price. Do you think that changing the spring rates all around would make it better?

Also, I would most likely be selling the parts I don't need such as the rear sway bar.

Thanks for your advice!

The springs are pretty stiff: 700/325.

Alright I agree with Sav.

That's a really good deal for a like-new SM suspension.

I wouldn't run that suspension on the street though. It's meant for smooth road courses.

It will go right into an early 1.6 Miata.

If you are wanting to autocross and drive it on the street you could get that setup and change the front springs for 500 lbs springs so it will be 500/325. That shouldn't be too hard on the street and would be good for autocross. I'm running 700/450 on my revalved konis and I don't think it feels very stiff. That's the beauty about Miatas, put those springs on a honda and you will loose your tooth filings and your kidneys will stop working

I'd buy it. It's a good start, and at least they're quality parts. I'm running 550/350 on Bilsteins with stock sways and it's fine on the street, but people have different definitions of "fine" of course. If nothing else you could experiment with the sways and if you can't make it work, buy some lighter front springs from Summit for like $60.

Same here. Good price on quality parts. Drop the front spring rates (you can buy summit springs for less).

I'd also install the rear bar though and at least try it connected /unconnected before I decided.

You can always get the shocks revalved.

I'm assuming that's with NB hats? If it is, grab it, sell the front springs, buy some ~450-500 springs, raise it, and it'll ride ok. I like my setup that's similar. No rear bar with a RB front.
