Yes. 90-05 and 2016-2019 Miata, Mustang GT350/R
Working on Mustang S550 GT, EcoBoost and 86 platform.


My 2019 Miata daily driver has ACE and the touchscreen controller.

the semi active is more for the street?

Ace are for whatever you want them for.

The standard Xida options do a far better-than-average job of working across a wide range of scenarios. With stiff spring rates they ride better than you'd expect, and with soft rates they still handle better than you'd expect.

Ace takes that versatility to 11.

Successful test at Sonoma this weekend. Temps were good but high winds kept us from going under 1:50 on street tires. Finally saw the right temperature gradients across the tire with the prototype strut flanges. At race ride height, with camber plate and highest offset camber chips installed, it's possible to crank in -6° camber up front. From past experience and pyrometer data, we started at -4° and that ended up being pretty close. Before this event, we had been limited to -1.7° on LF and I think -2.8° on the right side. As a result, we had been frying the outside shoulders of the front tires and never getting full grip from the tires. That's sorted now.


For pure competition use, most 86's on 255's will want between -3.5 and -5° depending on the spring rates, surface and tire being used. Ideal camber is dialed in by getting pyrometer reading, looking at lap data and driver feedback. On track or autocross, the tires wear evenly at those camber settings. On a daily driver though, that much camber makes the car tramline (follow pavement grooves) and wears the inside edges of the front tires. It's up to each driver to decide if they want a full highway friendly camber setting closer to -.5° , full race camber above -3.5° or a compromise in between. For dual duty cars that see some occasional track/autocross use, mostly canyon on the weekends and very little highway use, a setting between -1.5° and -2.5° might be a decent compromise.

The more straight line highway driving you do, the more you want the front tires around -.5°. The more hard cornering you do, the more camber you want. When the car is turning hard, body rolling a few degrees, the higher camber setting keeps the tire flatter for increased grip and also results in better wear.. but only if the car spends almost all its tire life cornering hard.

On our Mustang GT350 (also front struts like 86) with slightly lowered suspension and 305/30/19's, we ran -4.5° up front. That car was perfect on track.

So anyway, track testing successful, no problems encountered. We go into production in a week or two. Our custom springs will take a bit longer to produce so our best guess on when we can start shipping to customers is perhaps 2nd week December. We will make an announcement here and also an email blast to our mailing list when the site is open for pre-orders. Pricing should be finalized in a few weeks. We are really stoked to be wrapping up the R&D process and getting these launched.

EDIT: there's probably a joke in there about how pictures can make stuff look bigger than real life...

I'm fairly certain all Tractive shocks use a 46mm piston and a shaft diameter of 16mm. For comparison, Bilstein use a 46mm piston for their SLA shocks and I believe(don't quote me on this) a 37mm piston for their inverted struts with 14mm shafts.

So it's sounding like the camber chips will give us the ability to run close to -3* static without the use of camber plates?

I'm currently using RaceSeng plates on a stock shock/spring setup and I get about -3* with those maxed out. But I have issues with spring perch/inner fender clearance as well as endlink clearance. My hope is to be able to get pretty close to -3* and return to factory upper mounts for better NVH. I've also recently added adjustable control arms in the front if I need a nudge more to get the static camber I want. I'd rather get most of it through the strut flange, so as to not push the bottom of the tire too far past the path of the front bumper for drag reasons.

Yup.

Tentative pricing posted on our site now. http://949racing.com/xida-coilover-86.aspx

I emphasize that this pricing is tentative. It may change before we begin accepting pre-orders but we're pretty confident it will stay in that range. We plan to start accepting pre-orders in November for December shipment.

It's important to note that most owners will not need camber plates to reach -3° camber up front. If you have camber plates already, you probably won't need them. If you don't have camber plates, you don't need to budget for them. The adjustment range with included camber chips should be around -.5° through around -3.5° depending on ride height. So factor in any budgeting that you will simply re-use your OEM top mounts front and rear.

Love the insert bit, would love to see such more widespread among aftermarket suspension makers. Hate the bit that you guys are on other side of pond. By chance, do you have some reseller shop on EU side to make shipping/import/servicing simpler?

No EU dealers, sorry. Any Tractive distributor can service but only we have the Xida.

I'm sure it's posted elsewhere but who is your spring supplier?

[turbofan]

Spring supplier is proprietary. Hyperco springs will be available at additional cost.
