The Paco Motorsports’ 3″ lift kit began as a simple desire to daily drive a road course prepped track Miata in the winter months using larger than factory diameter snow tires. The kit, comprised of a fabricated bracket installed at each corner between the lower control arm and your existing shock assembly, is very simple to install and takes mere minutes to achieve. You can switch from offroad/winter mode back to street/track mode in no time!! Perfect for changing your autocross machine into a rallycross monster!!

 

Your alignment will change slightly, mostly the camber settings, and it may/may not be an issue, depending on how and where you’re planning to use your Miata. This kit does not add any wheel travel and is still subject to the limits of your existing shocks/springs. Up to 25″ diameter tires can be installed on Miatas using this kit without fender modifications. Larger, 26″ diameter 215/65-15 snow tires have been fitted to the car shown in the picture, with only light fender massaging required. If you want to go even bigger, consider the Mack Daddy of all offroad Miata setups, the full Offroadster kit, also offered by Paco Motorsports.

3" Lift Kit Instructions

The suspension on your Miata is cantilevered out from the front bulkhead. These braces reinforce the frame horns that support the engine and transfer all of the cornering and road impact loads into the rest of the chassis. This means that you’ll get less flexing and cowl shake, especially when running stiff springs and/or high torque engines.

Frog Arms were the first product that worked along these lines, but they’re no longer available. We took that as an opportunity to improve the design and increase the stiffness without changing the price. We extended the arms further forward and added a third dimension to the shape for maximum rigidity. Clever design keeps the weight to a minimum – only 6 lbs per side.

Simple bolt-on installation. Fits NA and NB Miatas. Powder Coated.  As it sits behind the shock tower brace, it should not adversely affect crumple zone performance.

The development of our Rallycross coilover package began as the third major offering from Paco Motorsports for offroad and lifted NA/NB Miatas.  First came the simple yet effective 3" lift kit, then came the extreme long travel Offroadster kit.  Both offerings are excellent at what they do, but there was a lot of middle ground untouched.  Some enthusiasts just want a little extra ground clearance on the cheap, and some want as much offroad capability possible.  The Rallycross setup fits squarely in the middle, and is even better than we expected, in terms of versatility on and off road.  Through prototyping and testing, the kit has seen many different iterations of shock design, shock mounting, spring rates, valving, etc.  Specific design intent for this coilover and mounting package followed these three main goals:

1. Max wheel travel allowed by the factory suspension — This means identifying and staying within the safe operating range of motion of the suspension’s upper and lower ball joints, tie rod ends, shock clearance to control arms, rear CV axle maximum angle of operation, etc.

2. Relatively low, progressive wheel rates — This is somewhat contradictory to more traditional street/track coilover packages, which use stiff spring rates to control body roll and aid in quick transitioning of weight transfer. The lower spring rates of the Rallycross setup allow the suspension to move through more of its range, soaking up rough terrain and promoting stability and comfort offroad. As with any quality suspension package, this required plenty of measuring, testing, math, and LOTS of trial and error before we settled on the final specs of all components.

3. Adaptability — We’ve learned so much from our customers over the years about lifted Miatas. Everyone has their own ideas and plans of how they want to take their car off the pavement. Many of our lift kit customers don’t even own a Miata yet. They just love the concept of a lifted Miata so much, they can’t wait to find an old roughed up example to throw some mud/snow tires on and go play offroad somewhere. Some are more serious and want to compete in national Rallycross events or Gambler 500 events, and we have some folks prepping for even higher levels of competition. Whatever the intended use, the Rallycross coilovers were designed to cover a multitude of intended uses.

— TECHNICAL SPECS —

Approx. Ride height range: +1″ to +4″ compared to “stock”

~8.5″ total wheel travel all around (max bump travel could be limited somewhat depending upon large tire diameters interfering with factory wheel well sheet metal. Anything below ~26″ diameter tire should allow full travel.)

Aluminum bodied shocks with 9/16" pistons, threaded spring perches and heavy duty bump stops

Inverted rear shock design allows the high range of travel we achieve, which is traditionally a big limitation in rear shock setups on Miatas.

25"-26" tire diameter without major fender/body modifications. Up to ~29+″ possible with extensive fabrication

--NOTES--

At higher ride heights, front camber adjustments will be limited to around zero camber to +1 degree camber.  Our extended front lower balljoints add up to 3 degrees of negative camber to allow more ideal alignment.  Similarly in the rear, care needs to be taken when using high ride heights and too much negative camber because of the extreme angle of the CV joint at full droop (when the suspension is fully extended downward).  Factory CV joints have been known to break with extreme use.  Stronger axles with beefier CVs and more range of motion are available.  Paco Moto Upper Rear control arms recommended on ALL lifted Miatas for proper camber setup and max CV axle angle limits…also provides for clearance with certain wheel/tire combinations, and more ideal wheel alignment.  Finally, the rear swaybar requires extended links to allow full wheel travel, which we also offer separately.

This is a DIY or WIY (weld-it-yourself) kit that includes everything needed to make your own pair of our popular Strong Arms for your 1990-2005 Miata -- Just Add Welding and your choice of finish!   This is a perfect opportunity to save a wad of cash while SIGNIFICANTLY improving your Miata's chassis and have a bit of fun with a quick, satisfying project -- maybe to share with someone just as enthusiastic and hands-on as you!

Our Strong Arms were designed from the beginning to be as easy and straightforward to produce as possible.  The design is self-fixturing, meaning you don't need any special jigs or tools to make them accurately.  All the parts only fit together only one way, and are tabbed-and-slotted to be positioned perfectly to carry the chassis loads efficiently between all the bolted hard-points.  The laser-cut steel parts come pre-formed and ready to weld right out of the box.

You need a MiG, TiG, or even a stick welder can work -- and of course you need the skill necessary to weld effectively!  These are a fairly simple product to weld, but they shouldn't be your first experience!  We have a welding guide available, showing where to position each of the 30 welds required per arm.  --THESE SHOULD NOT BE WELDED "SOLID"--  In the guide we outline each weld, which has been strategically positioned and sized to maximize strength, minimize weight, and prevent any warping from too much weld heat.  Click here for the welding guide PDF...

And click here for the instructions to install Strong Arms on your Miata once you're done building the kit.

Our standard prefabricated Strong Arms are powder coated with a slightly textured, black matte powder coat.  Once welded, we recommend some sort of powder coating or durable paint process for best corrosion resistance, but there's nothing wrong with using a few coats of spray paint from a rattle can either, assuming you have that skill too! :)  You could also throw caution to the wind and run them bare.. we don't recommend it, but at least the rust will be hidden behind the fenders!

This kit will come complete with all hardware necessary for installation on your Miata.
