BRIAN's APPLICATION NOTES: Our Progress Bars remain top of the food chain as our best bars, and my suggestion for any customer planning regular track days is spend a bit more for our higher rate Progress Sways. These were developed on our Budget NC Racer project as a budget alternative that is all about max bang for the buck and though we tested them on track my suggestion is that these are aimed more at dedicated street customers seeking a sway upgrade on a budget. IF the question is whether our Progress Bars are better, the answer is YES our Progress Bars are better and the better choice for the track and autocross enthusiast (higher spring rate for even flatter turns, better finish, best hardware). But if the budget is under $300, nothing out there comes close to the features we packed in this budget option at this price level. Four adjustment holes front and rear for LOTS of adjustment potential with bar rates that make a big difference over stock. If track days are in your plans our Progress Bars will serve you best, but for the money nothing is close to these budget bars. All hardware included, and the grease, making a complete setup at a great price!
Endlinks? Stock links are fine at stock height. When you change to a stiffer sway bar AND you lower your MX5 you likely want adjustable endlinks for good geometry (bar ends level as possible), and in the rear you need shorter links to maintain adequate clearance between the sway bar and subframe. Thus, those lowering the Miata see RoadsterSport Endlinks for the front for any amount of lowering, and our same RoadsterSport endlinks will work for the rear if lowering only a mild amount, OR if lowering more than 1" then consider extra short links that can go below 80mm length like the SuperPro rear links.
Tested by our entire team at numerous local Autocross Events, many Top Time of Day results on our Budget NC Project, and many track days too including 3 days of back to back at Laguna Seca Raceway for the ultimate in torture testing!

INSTALLATION...EASY STUFF AHEAD:
1. Open BOTH ends of the box to find the hardware. Jack the rear of the car up and secure it with good stands, no need to remove the tires. Unbolt the top of the endlink on both sides of the car. Careful, the endlinks should be unloaded but can still pop up or down with considerable force. You will need a socket and a standard wrench, both 14mm, for this job. The bolts are also pretty tight, so watch those knuckles. Once the ends are free, remove the four bolts holding the center D-brackets in place and take the bar off the car.
2. There are three endlink holes on the new bar which allow you to fine tune the balance of the car, we suggest you start with hole nearest the bar ends.
3. Apply a thin smear of included grease to the inside of the bushings before wrapping them on the bar. Fix the new bar and bushings onto the chassis and cinch the nuts down hand-tight. Note that orientation of bar is with middle of bar, the angle bend, pointing upwards. Push the endlinks into place and fasten hand-tight.
4. Put the car back on the ground to settle the suspension. Finally, snug up all the hardware good and tight. Tighten the center brackets to about 12 to 14 lbs.-ft.
5. Now for the front bar. Jack up the nose as high as possible, and this time take the tires off. Remove the (disgustingly oily?) plastic front splash pan, then unbolt the top of the end links just like you did at the back. Remove the four bolts that hold the center brackets. On cars with a/c it can sometimes be hard to get the bar out past the hoses, so be ready for some coaxing.
6. Slide the new bar more or less into place, then grease up another set of bushings and install them onto the bar. Bolt everything back up with the included brackets, even out the bar from side to side, and hook up the endlinks last (we suggest you start with FOURTH hole from bar end at both sides). You'll notice that in the front, the ABS wires are held to the subframe by a small little bracket very close to the sway bar bracket. Two spacers are provided to move each of those brackets up and off of the sway bar bracket/bolt, with a longer bolt also supplied to pair with that spacer.
7. Lower the car to the ground to settle out the suspension, then reach in and final-tighten all the fasteners. Raise the car once more, refit the plastic splash pan, and you're ready to put the car down for its test drive. The front install should take less than an hour, and again there are no real hassles to watch out for. Best of all, no alignment changes will occur from swapping out either bar.
After making a major change to the suspension like we did here, you need to resist the urge to dash off to your favorite twisty road and push the car to its limits. For a little while, those limits are again unknown to you, so probe the new feel carefully. The chassis feels so much flatter with a lot better grip through the comers that a false sense of security often settles in. While beefier bars will make the car hunker down flatter longer, they also diminish the amount of warning you get of impending trouble. Get to know the car's new over- and understeer limits again before you get too cocky! Though we suggested some mild settings for starting we suggest SCCA Autocross events as the best place to really learn and test and tune in a safe environment the new setup to your particular balance preferences!

Great setup and really make a difference in the handling. I have a pretty stock setup with Koni STR shocks that I installed a few years ago. I also have the Mazdaspeed repro brace that I purchased from Good-Win. I have them on the soft setting but will probably play around with different settings later. The install went smoothly. My advice is to watch the step by step instructions Flying Miata has posted on You-Tube. I looked at their sways first. Good-Wins are a better value with a greater range of settings. I also liked the fact that the rear comes with new brackets, FM's don't provide them you use the old ones. I'm not a track guy but I like driving up to the mountains for rides. I just wanted a little more planted ride.
My first suspension modification. Combined with new adjustable sway bar end links. Installation was a bit more challenging than expected: Radiator required movement to facilitate installation. Setup as advised using holes nearest bar ends on the rear and fourth hole from the bar end on the front. Car is used for sporty street driving (mostly cornering at higher speeds). A NOTICEABLE improvement! Corners flatter with improved control.
My car has about 45,000 miles on it. I don't track it and don't expect to do so. I don't consider myself to be an aggressive driver, but I do enjoy pushing my abilities on the mountain and coastal roads in the area.
I was looking for a way to reduce body roll a bit without giving the car a stiffer ride. I installed the rear bar with the softest setting and the front bar on the second from softest. The result was the flatter cornering that I was looking for and still a comfortable ride. I recently took the car on a club ride through some Southern California canyons. For me the cornering was comfortable and flat without loosing the backend. Both bars have stiffer settings that could be used for a more aggressive driver. I'm very satisfied with the change.
Note on installation. Removing and installing the rear bar is easy and uncomplicated. The front was trickier on my NC2. Removing the stock front bar wasn't difficult. It was easy to wiggle past all the radiator and AC hoses. It was very difficult to thread the new fatter bar past the radiator and nearby hoses. I finally unbolted the two bottom radiator bolts so I could push the radiator forward. That made all the difference. Having done that at the beginning would have avoided a lot of scratches on the new bar. Also, I found I needed to remove the front fender lining. I recommend having a supply of body panel clips available. Inevitably, some will break when being removed.
I never plan to track my car, so when I saw this cost effective option and read Brian's notes, this was the choice for me. I really enjoy wrenching on my project car, and this was a great weekend project for me. The car feels much more solid, which is the payout.
A few helpful notes. 1. My end links were in pretty rough shape. If you are doing work on a high mileage car, you may be resorting to cutting them off and replacing them. I had purchased the RoadsterSport end links and am glad I did. My next project is installing some Konis, so having the end links sorted out is huge. 2. There are some spacers and bolts included with this kit to give the ABS holders some extra space because of the larger bar and brackets, but I found that the bracket still overlapped the screw holes and the included screws didn't really fit.
