FM V-Maxx XXtreme coilovers for NB - Track Pack

Improved! The rear shocks now have offset bushings for extra clearance between the spring and the halfshafts. This gives you a wider range of height adjustment.

Our V-Maxx Classic suspension is very popular, but there's one thing missing from it: adjustable damping. So we worked with V-Maxx to bring an adjustable set to market. They call it the XXtreme.

The XXtreme Track Pack comes with stiff 504 lb/in front and 336 lb/in rear spring rates. They're aimed at cars that spend most of their time on the track. It can still be driven on the street, but it is stiff. Early Miatas should have some sort of chassis reinforcement in order to take full advantage of these spring rates. If you'd like a softer option more suited to street use, these are also available with the Sport spring rates 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? One of the problems with a lot of coilover setups is that the spring can go loose under full droop. When that happens, there's nothing to extend your shock any further so you've essentially reached the end of your suspension travel. The secondary spring in the V-Maxx coilovers helps to extend the wheel further and give more useful suspension travel.

The secondary springs are 112 lb/in, which gives them enough strength to overcome the damping of the shock. On most cars, they are just barely fully compressed at rest. Other systems will use helper springs as soft as 5 lb/in, which simply isn't enough to do anything useful when you're moving down the road.

Since the spring perch is adjustable, you have full control over ride height and cornerweighting. A 1/2" shorter rear shock body gives extra compression travel for improved ride and handling, even at lower ride heights. They have a two-year warranty. Note that this kit doesn't include upper shock mount parts, as you can reuse your stock shock mount parts. It's a good idea to replace the rubber bushings though, that kit is listed above. 

They're not quite in the same league as the Fox in terms of outright speed, but they do offer excellent value and are a good choice for someone who wants an inexpensive coilover setup. Includes both sets of springs, four shocks, adjusting tools and bumpstops. Not compatible with FM's rear upper mounts, as this combination provides more compression travel than the suspension can physically deliver. Note that this kit doesn't include shock mount parts, as you can reuse your stock shock mount parts. It's a good idea to replace the rubber bushings though, that kit is listed above. 

Please note that these were designed as a performance setup, and thus work best at a lower-than-stock ride height. We recommend setting them at approximately 11.5"-12" in the front and 12"-12.5" in the rear, although they can run higher.

Customer warning: Flyin' Miata is the exclusive US distributor for Miata V-Maxx suspension. Kits from elsewhere will not have a warranty nor will they have the correct spring rates. Buyer beware!
