What a timely thread I was just about to get advice on SS2 vs tarmac 2 with 949racing topmounts. I would love something like the Xida but price is a bit too much for my use case.

I would be very interested in this option depending on cost and time frame.

Tecnas will have about 60% of the total damping range of Xidas. So on the softer settings you wouldn't notice much difference. But if you're running say 255 super200's, 4" splitter and a huge wing out back and are needing the stiffer damping range, Xidas would offer better performance.

TBD. Possibly the same -6 Xida eccentrics are capable of, maybe a bit less.

Very interested! Absolutely loving my CSG Teins so far, but always keeping an eye out for other options. Monotube, inverted strut, and helper spring is very alluring, and a market differentiator at this price point.

Will these be designed around a certain swaybar combination or targeted alignment specs, either in Touring or Sport spring rates? If I recall, the CSG Teins were designed around stock front/rear sway bars (this is what I'm running right now).

Blub, our project car set lap records at every track it visited and ran just a 22mm Perrin front and OEM rear on 265/18's. We found that better shocks, more camber and balanced aero obviated huge sway bars. Short answer, we never recommend a larger rear bar on any 86 anyway, 22mm for most, possibly 24mm for Hoosiers and big downforce. For smaller tires and no downforce, still the same bars or maybe 20mm front.

*starts saving*. 6 to 12 months. Check. Don't forget the "Canada salt" package please.

Good call - will these be streetable through winter and salt without concern?

As durable as any other high quality coilover on the market. Salt destroys everything it touches. One key feature that separates our Xidas from the rest is that they have standard rubberized nylon shock covers. We found they protect the shocks much better than the traditional rubber boot inside of the spring. Tecnas will have these too.

Here is a pic of one of our Miata Xida kits with included covers.

Is there any reason you wouldn't change back to the stock suspension for the winter months?

Being lazy and having enough nice days during winter that driving on stock suspension would be a bummer. For folks that have months on end of snow/slush/salt it might make more sense

Ah, I assumed you were going to be plowing through salt and snow daily. If that were the case I switch them out when doing snow tires.

Specifically engineered coilovers for our platform that'll be nice for the street? Sign me up! I miss being able to carry drinks in the cupholders without spilling.

The BRZ is quickly becoming the daily/occasional track car rather than a dedicated track car, and the monosports aren't the best of compromises. (also, i've tried 3 different sets of endlinks, and they ALL hit the chassis or shock body as soon as I go under -3* camber.

I think probably 25% of the development time with Xidas was getting the front end links dialed in. Proprietary turnbuckles, brackets and casing offset. All of that geometry will be replicated for Tecna.

We had talked to owners of a few other high-end 86 coilovers and a recurring theme was horror stories about the complete lack of engineering for the end links with high camber settings.

I can attest front end links are a pita with this platform

I'm thinking Ohlins might want a word with you.
