Yeah, the bilsteins were stiff feeling but then just kind of all over the place on any mid corner bumps.

Got the Tecna in, first impressions are good. Had them set at 15 from full stiff as a starting point with the sport springs. I softened them up in a few steps and am going to be trying 6 clicks from full soft on my commute tomorrow (I ran the Xida soft as well). On the smaller road imperfections, they are amazing, not quite as butter as the xida were on those, but very close. Throwing them into mid corner drain grates and such, they are far and above better than anything else I have driven on that are not the Xida.

So, so far, my only complaint boils down to "Well, they aren't Xida". The back end almost feels like it is launching in the air over larger sharp bumps as well, but the back end of my car is heavy and currently sitting 1/4" or so below the front (I just left the preload where it was out of the box for the first drive, I will fiddle with it tomorrow evening.)

Overall, for the price, I am very impressed, build quality is fantastic as well compared to most other coilovers I have handled (again, just one step below the Xida, but we all expect that). I will commute on them the next few days (8 miles of traffic on the freeway, then progressively smaller back mountain roads from there. It will be a good test.)

Possible you are too low in back and bottoming. Shouldn't kick unless its getting into the stops hard and that only happens if either the car/driver combo is above like 2650# and/or you're below 120mm pinch weld

x_25

We were over 2650. Car is somewhere between 2250 and 2300. And then me (another 230) and my girlfriend and some tools, along with the back end being heavy since I ditched the AC added a sound system and a roll bar (all weight in the back).

It's over 140mm pinch weld height without us in it, since the lift pads sung under it fine.

If that was getting into the bump stops I am impressed, it was not jarring at all.

140 empty probably translates to about 120 laden in rear for your scenario. So yeah, bottoming. Just crank some more preload in, a lot more I think. We engineered in a bunch of range and your build/use is within that window.

Yup! Tons of space left (and part of why I went with the sport package over the softer springs. I load this car up either on sticky tires or with things fairly often). Even right out of the box, they are impressive, dialed in, they sgould be fantastic.

Turns out they were at ~130F/127R, got some miles on them, adjusted the height to ~140F/146R and set them to 6 clicks from full soft. They just make the road vanish now unless it's a BIG bump/pothole. I am very impressed. Still need more miles for a proper review, but I already have decided they will be staying on the car and the Xidas will be moving on (the option was put the Xida back on this car and the Tecna on my beater NB if they didn't quite do everything I wanted).

My first impression is pretty good, just tried setting 1 and it is very smooth. I definitely need to add some more preload, mine settled after a few miles to less than 120. I also usually run a full tank and some tools in the trunk.

Ok got the preload reasonable. I had to increase 5 turns in front and 12 in back. I ran on setting 4 for 200 miles round trip, easily as comfortable as the stock kyb inserts I had before. We only got 3 practice rounds and I wasn't about to change the settings before elimination. Next week I should be able to try some different settings for launching. Seems like it might need to be a little stiffer for burnouts and launches .

With the damping forces utilized in Tecnas, there is no need for a digressive piston. When you're valving a shock with a really high damping force at low piston speeds like Xidas, a linear pistons create too much high speed damping. Tecnas have only a modest "nose" of low speed damping and we get enough bleed by balancing gas pressure against needle seat flow and shim stack.

Short version: Tecnas don't need digressive pistons

You're a Xida customer but it'll still be interesting to see how these work for drag racing on a boosted Miata

I am going to get these dialed in. I imagine different settings for front and rear. I was watching my videos and I clearly need more damping in front, but I have only tried the 4th click all the way around. I am also not super confident about my pinch weld heights, my garage floor is crap. I weighed my car without me, but a full tank and tools 2416#'s in current form.
I love that Sac has a scale, but the thing is scary narrow, barely fits my car.

I figured out the tossing inssue in the rear. It was caussed by me being a dumbass and setting one of the bushings up to bind. I changed the rear upper outter ones recently and tightened them at full droop when I put it back together, not realizing the reason I could get away with that onnthe old ones was they would slip and take out the preload after.....

Anyway! I am finding I need to run the shocks set a lot stiffer than I expect on these. But with a fairly heavy car, sport springs, and lots of bad bridge expansion joints, that seems to make sense. The poor thing gets really tossed aorund.

Ok just wanted to say that I have been loving these. I was able to hook decent 60' times on setting 10. The thing is still amazingly comfortable even at 12, the highest I have tried yet. I think the sweet spot for launching is somewhere around 9, 10, or 11, with street tires anyway.
Additionally I was blabbing about how well my car handles and puts the power down now. One of my friends, who worked for some car magazine years ago and seems to know everyone, said that I was the only person he ever heard say my street driven car is better after installing coilovers. He said everyone always says that they ruined their car. He doesn't know about Xidas either. But yes, you guys are the only ones he doesn't know.

Thanks again, I am a happy customer!

Hell yeah, thanks for the great feedback Carlos. Glad you're enjoying them!

I installed my tecna coilovers last week and aligned my car to Supermiata’s street specs. Then I headed off to Miata’s at the gap. All I can say is wow.
Wow, what I had was terrible.
Wow, I can’t imagine a better suspension for the money.

My car was nervous and easily unsettled by mid corner bumps with my old suspension. Now it’s supremely smooth and controlled. Don’t get me wrong big bumps are still big, but the car is way less effected by them and almost instantaneously settles back dow. It feels very direct and sure footed now. I was able to drive some serious miles on some great mountain roads and am very happy with my purchase of the Tecna coilovers. For my use case they are everything I was hoping for. Thanks Supermiata for producing an outstanding product for spirited mountain drives as well as the day to day drives.

Might sounds a bit trite, but every here at 949 is an avowed Miata nerd. It means a lot to us to hear folks being so stoked on the toys we worked so hard to bring to market. Enjoy!
