Does our Miata need more rear bar? Perhaps that will help.

Our 2021 season ends next week, and the next one starts in the middle of January. In that tiny bit of time, can we make some chassis improvements?

We've been discussing our setup with Andy Hollis and have gone back through the STS project car that he built with us. One thing on Andy's suggestion list for our car: Maybe a bit more rear bar.

[What is an anti-roll bar and how does it work? | Handling Basics]

How big? He's thinking that replacing the stock 12mm bar with a 14mm rear bar would do the trick. Up front, we’re running a hollow 1.125-inch Racing Beat bar. (In metric, that’s about 28.5mm.)

A 14mm bar came on the Mazdaspeed Miata, and we got ours via Treasure Coast Miata. It even came with the bushings and brackets. The shop shows rear anti-roll bars starting at $25, with front bars as low as $20.

The catalog isn’t limited to anti-roll bars, as Treasure Coast Miata also offers a full line of new and used parts, including things like rebuilt cylinder heads, blueprinted hubs and fiberglass body panels.

 Bars starting at *$20*????   Wooowwww that's awesome.  The vette tax makes exactly zero parts beyond occasional plastic clips less than $20.  A sway bar?   Some serious coin...

In reply to jfryjfry :

I know, right? This car once had a Racing Beat rear bar. I have a feeling it might have wound up on one of the crashed Miatas out there. 

And we need to do a field trip to Treasure Coast Miata.
