V-Maxx coilovers give you an adjustable setup for ride and handling. FM sway bars let you adjust your handling balance and make the car corner flatter and transition faster. Mix them together and you get the V-Maxx stage 2 kit - an excellent recipe for handling. It's what the Hammerhead teams used at the punishing Targa Newfoundland.

About the sway bars:

Sway bars are used to make your car corner flatter and react faster by keeping the body (and all the weight) under control. Ours are set up for neutral handling and are adjustable so you can tailor the handling of your Miata to your own driving style.

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 two settings in the front and three in the rear for fine-tuning. Includes brackets and urethane bushings with waterproof grease.

NB sizes are 1.0" front and 0.625" rear.

About the V-Maxx:

The XXtreme Sport package comes with 391 lb/in front and 258 lb/in rear spring rates. It's a decent all-around setup - stiff enough for track and autocross use, firm but useable on the street. Those are the same rates used on our non-adjustable V-Maxx shocks. If you'd like a track-oriented setup with 25% stiffer spring rates, check out our Track Pack for the same price. The springs are also available separately if you'd like to have multiple sets on hand.

So what makes them work?

The adjustable shock damping is well-matched to the springs. A 1/2" shorter rear shock body gives extra compression travel for improved ride and handling, even at lower ride heights. Since the spring perch is adjustable, you have full control over ride height and cornerweighting. The spring rates are 391 lb/in in the front and 258 lb/in in the rear, which gives a good handling balance.

The stock upper mounts are retained. They have a two-year warranty and are available in a TUV approved version with different spring rates.

Your shock bushings are likely pretty tired by now - we recommend replacing those while you're in there. 

Improved! The rear shocks have offset bushings for extra clearance between the spring and the halfshafts. This gives you a wider range of height adjustment. We have also gone to a single long front spring to give maximum travel without coil bind.

Great parts, poor instructions

Ordered kit for a 2001 nb miata, fits and works great, smoother ride than worn originals.
Instructions were nonexistent, the QR code led to page to buy parts, and trying to find reliable references was difficult.

We did have an issue a few months ago where the QR code on our included instructions card pointed to the wrong place on our website, but that's been fixed. You can also always find a product's instructions on the listing where you bought that product. We're sorry for the difficulty, but remember that you're always welcome to reach out to our customer support team for help. They can be reached via phone, email, chat, Facebook Messenger... all sorts of different avenues.
