"Slidey, neutral, sublime. You take the car by the scruff of its neck and just chuck it toward the horizon. It makes a stock car look lethargic, roll-heavy, almost stupid. And at no time does it even hint at biting you. Woof. So good." - Road & Track
This is the best suspension available for the ND Miata. It takes the fundamental nature of the Miata and improves on it. The roll is gone, replaced by quick reflexes - but not at the expense of travel or compliance. It's the same basic suspension used on our acclaimed V8 conversions, which has been praised for its organic, flowing feel.
This package combines our Fox suspension and sway bars.
Our swaybars are hot formed from 4140 CrMo spring steel. This means they're stronger than the cold-formed bars found elsewhere. We've designed them to keep the same handling balance as your stock sways, but they have three settings in the front and three in the rear for fine-tuning.
The front bar is a tubular design with 1.125" diameter and 0.188" wall thickness, while the rear is a solid 0.625". Both have three adjustment holes and include polyurethane bushings, brackets and grease.
The shocks are designed to keep the full range of suspension travel, including matching the massive 7" rear stroke. As with all our FOX shocks, they're aluminum bodied monotubes with adjustable rebound so you can fine-tune the shocks to your needs. Thanks to some careful fine-tuning of the valving, the car rides extremely well.
The included Sport spring set is intended for performance street cars. It's comfortable enough for cross-country drives, but makes the car into a great back-road tool and very eager toy. It uses 400 lb/in front springs and 225 lb/in rear springs. On the RF, we use 250 rear springs to balance out the heavier rear end.
For track use, you can run higher spring rates. We've found 600 lb/in front and 350 lb/in rear works pretty well - those are the same rates used on the Global Cup Cars. We do not currently offer this spring set, but any good coil spring manufacturer can provide them.
The springs come with helper springs front and rear, as well as a custom front upper mount. This is a complete coilover setup with everything you need to install.
There are a lot of little details on these parts that aren't immediately obvious. The springs sit on a high density plastic ring that acts as a bearing, allowing the spring to rotate on the perch without the expense of a bearing. The internal washers are disc ground for high accuracy, giving more consistent behavior of the shock. Even the body of the shock is given Kashima coat, which is a superior form of hard anodizing to protect the shock under the worst conditions. Even the shocks are light - 40% lighter than a Koni. Total weight per corner (springs, shocks, bushings, helpers) is 7.25 lbs for the front and 7.05 lbs for the rear. Made in the USA.
1-Year Limited Warranty for the original customer against defects in materials and/or workmanship. Custom revalving services are offered through Fox for $35/shock.
