Applicable to: '90 - '97 1.8 liter

These springs are powder coated red. Nicely labeled front and rear.

I was not very happy with this product. I also installed KYB-AGX adjustable shocks at the same time. Per the JR website and the vendor where I purchased them, they were supposed to lower the car 35mm. On my 97 STO, this was actually 50 mm. This put my car at about 12.5" from the center of the wheel to the fender lip. I even trimmed the rear bumpstops in anticipation of limited travel. Unfortunately, this wasn't enough. It looked great but I lost grip on anything less than a glass smooth road. The slightest bump or dip in the road bounced the car off of the bumpstops. I had to adjust the shocks up to about 5 out of 8 to prevent this. Unfortunately, this made the suspension so stiff it was almost unbearable. After messing with the shock settings for about three weeks, I finally gave up and put the stock springs back on my car. Still handles great and is actually comfortable to ride in again. I would suggest looking elsewhere for handling improvements.

The vendor and Jackson racing did give me 80% of the value as a refund so at least they stood behind their product. I have other JR products on my car and just think they missed the mark with their springs.

Jackson Racing Sport Lowering Springs

Applicable to: '90 - '97

Coil springs are powder coated in bright red, with a nice plastic coated finish. Too bad nobody can really see them!

Free length is approximately 2 inches less than the free length of my 125k OEM Mazda springs. These springs do not feel much stiffer than stock, which is what I wanted. I think the med-soft spring/stiff shock combination is excellent on a Miata. I do not think cornering grip is changed at al, but transitional behavior is MUCH improved. When mounted on Konis set on the middle perch front and rear, these springs dropped my car about 1.5". I measured the front from wheel- hub-center up to the bottom of the finder lip, and I'm at 12.5". I have not measured the rear, but it looks like it's dropped an equal amount, versus stock. The rear is still slightly higher than the front when nobody's in the car. I chose NOT to trim my bump stops. However, the rear is still bottoming onto the bump stops just a BIT too much for my taste. I will first try moving the springs up to the TOP Koni perch on the rear. If this doesn't help enough, I'll trim my bump stops.
