The low down
The Tecna coilover was engineered from scratch to be the best riding coilover in this price range and still allow lowered ride heights. We think of these as daily driver shocks, not race shocks. If you are focused on the ultimate handling in a competition type environment, we recommend stepping up to Xidas with much higher spring rates. Tecna damping range is roughly equivalent to the softest 35% of Xida range. Perfect for a daily driver, canyons and some casual HPDE or auto-x. Tecna do not require service and are intended to last the life of your vehicle. Ideally suited to 185-205 width tires above 280 treadwear on 6-8″ wheels. For wider, softer compound tires, look at our Xida options.
Why one piece body?
Body, shaft lengths, stroke, mounts, and internal configuration are specifically engineered and maximized for this application. They are unlike 2 piece, length adjustable coilovers that use an existing universal short cartridge with an extension adapter to make it fit. The advantage of a one piece shock is full bump and droop travel without needing to choose one or the other. Additionally, a one piece shock is all shock, no hollow adapter that wastes space. That means more oil and nitrogen volume for better pressure balancing and increased shaft stroke. A telling feature is the helper springs (stroke!).

Set up:
Typical available adjustment ranges are front pinch weld heights between 4.75″ and 6″ with driver. Tecna will give the best combination of handling and ride with stock or a small aftermarket front sway bar. 1″ max front, OEM rear. More sway bar than that will only reduce ride quality without any meaningful increase in grip or handling.
Front fender liners:
The standard front setup provides enough bump travel for a 205/50/15 tire on a +36 offset 15×8 to just barely kiss the fender liner at full bump. Wider tires or lower offset wheels will require removal of plastic inner fender liners in front. If running 245/40/15 tires or touching the front fender liners on big bumps, add our shock mount spacers or travel limiters to create enough space for your oversize tires.
As much as we are presenting these as street shocks, I see budget enduro teams running these against our reccomendations. They aren't as capable as Xidas on track but still way better than DIY Bilsteins and chinabay stuff in this price range.
The giant preorder banner below that and details about the preorder below that sort of overrides it. But yes it's a brand new site and we're still tweaking. Sorry! Shipping in January.
Our old mobile site would not display full content so we had to turn it off. At least now the mobile site works the same as the desktop. Yay.
After receiving many questions about spring rate increases, we're considering adding a second option.
Same exact shock, just with different springs. 9/6kg is the max we feel comfortable with on a 2600# Miata, which is the median weight for casual HPDE and auto-x builds.
The spring upgrade cost would likely be about $100, so $1475 shipped in the US.
6/4kg (336/228) Current rates
9/6kg (504/336) proposed optional rates

What say ye?
As one of (I think) many people running RS4s or similar tyres on the street, I think 9/6 would be a great option to have.
Also, not enough of a difference to be worth the effort. The 6/4 covers those who want a focus on ride quality with great handling. 9/6 covers those who want a little better body control for grippier tires/track driving. Anything more, Xida.
If there was a really compelling purpose to do something between Street and Sport we'd consider it, but not much point in just splitting the difference.
I'm going from Bilsteins on FM springs to Tecnas so I'll post about them once I can do a comparison.

Raise the cost for everyone or just the cost of the Tecnas with stiffer springs?

Did I have this conversation with you on instagram?
I'm 90% sure I'm in for a pair of 9/6. I run 700/400 Xida Race for casual HPDE and cruising on 205/50r15 ECFs. 1.6 making about 115hp.
The appeal of the Tecna is (1) lower maintenance and (2) higher ride height--I'm close to full height on the race, and I'd like to go up about 1/2".
It seems to me that spring rate-wise, the 9/6 on a longer body should be functionally similar to the 700/400 on the Race. Obviously giving up the very low friction seals.
Am I wrong on this thinking?
PS: Did you discontinue the XLs?

All kits. The more we produce of any given product, the less it costs. Adding variants increases price of every variant. NA/NB Xidas have over 1,000 different possible combinations, each assembled and packed here in our shop. Tecna have 1, assembled and packed in the factory in Taiwan.
It's funny, Tecna have more in common with FM Fox than any other 2 piece monotube coilover. This level of supply chain management is key in being able to offer a $2400 equivalent kit for $1375 shipped. We want to stick to that price as long as the world economy will allow.
Adding the 9/6 variant might be a necessary step though. Which is why we asked that specific question here. Of course, some folks will toss our springs and experiment with their own. But we won't offer a springless kit.

no super low friction seals, larger piston, high pressure nitrogen charge (tecnas are low-pressure), no digressive valving. So maybe not quite functionally similar. But they will achieve taller ride heights, still ride great, require less maintenance, and work well on track with your wheel/tire setup.
In response to a lot of folks asking for stiffer springs, we quickly tested and will be adding a 9/6kg (504/336) option. It'll cost a bit more and it's not on the website yet. If you are interested in a set and want to take advantage of the Double Orange Cash (store cashback rewards) and free Delrin Shift **** or Forged lugs, you need to get your order in by Friday Oct 14th 6pm PST.
If you want the Sport Springs and the deal, just order standard Tecnas and let us know in the customer notes that you want Sport springs.
Special intro offer for freebie items ends tonight Oct 14th, midnight PST.
For those of you that are interested but don't want the lugs of shift **** we're offering, we'll give you a $40 store credit towards any other item in our store instead.
