Progress Technologies MX5 FRONT Sway Bar

Between this and the Konis, I don't worry about scraping the paint off my door handles at autocross.

Install was a bit of a pain, a second set of hands to help watch one end while you work on the other is a huge benefit. That is going to be the case for any one-piece sway bar for the ND Miatas though. Bigger issue was getting the OE front bar out, but it becomes pretty easy if you're willing to use an angle grinder.

Just what an ND Miata needs! I had my local shop install this along with a Progress Technologies rear sway bar. So I can't speak to the ease of installation. I can say, that the owner and operator of said shop (who has specialized in Miatas for over 25 years) heartily recommended these due to Goodwin-Racing's reputation for making solid parts. And I dare say that after having seen these in person, they're dang near over engineered. Particularly where the end links attach. No question these will last the life of the car.

On to the fun stuff. Out on the road with these installed and in the 'soft' settings, lateral body motions are greatly reduced. Cowl shake is a little more noticeable on poorly kept pavement. But it's certainly not whip inducing. Also, to be fair. I am still using the stock coil overs featuring Bilstein dampers that came with the car. I can't imagine using the stiffer settings on the road. That said. I haven't taking the car to an autocross or track to test stiffer settings (thanks COVID-19...)

TL;DR: Get these if you want your ND Miata to sway less and do so for the life of the car.

As mentioned by some other reviews, the install takes a while, it took me around 3 hours on jack stands. I took the other reviews advice and used the FM method and that went well for most of it, but removing the sway bar end up and over the frame rail on the passenger side is a pain. It takes a bit of force as you have to deal with the rubber bushings on the stock sway bar. I would recommend having someone help guide the other end of the sway bar at this point because you need to make sure you don't damage the wiring or fender on the driver side. I installed the end links in the middle hole as suggested.

As for driving, the difference in handling is night and day. I was driving on some on-ramp/off-ramps that have long curves and the car seems so planted now. Even in roundabouts, the car has minimal body roll and it is so much fun. I can't wait to see how it performs autocrossing!

Installed alongside the Progress RSB. This is my first experience with sway bars, and I have to say: I'm impressed. The car stays almost completely flat in long, fast corners. This instills a lot of confidence.

The install was definitely time consuming. I used FM's method (fan shroud removal) because the instructions/pics that came with the bar were not too useful.

Definitely a little tougher install than usual but with some patience it's very possible at home

This bar fits perfectly and looks awesome! I have run one CS autocross without it and one with it on softest setting. Car had light understeer on entry but that will easily be adjusted out once shocks are available... The main difference that it makes is much less wheel spin due to less body roll. This helped to my best finish in 2 1/2 years.
