Boots are a good idea if you frequently drive on dirt roads or inclement weather. There is not room between the shock and the spring however so the boot has to go over the spring like the one that inertia laboratory sells.

No cost effective way to share the Xida program with dealers, sorry.

Are these the neoprene ones? I bought the neoprene ones from raceshocks.uk (UK Tractive dealer) for my Xidas, but they looked way to close to the rear driveshaft when installed. I was also mindful that the damper would probably run very hot if run on track like that, since there was very little exposed damper left. Maybe I need a tow car and enclosed race trailer for all the salty winter trackdays.....

Contact Chris for more details: Inertia Laboratory

Correct, race shocks for pavement don't have dust boots.

Inertia labs can rebuild Xidas with a more expensive stainless seal for daily driving, 'should' reduce or eliminate early failures due to daily driving.

There is the option, but it hasnt been tested.

A no is a no, but I really cannot see how manufacturing the shocks in Tractive, shipping them overseas, and subsequently shipping them back to Europe is more cost-effective; maybe I am missing something. Also; "dealers" is precisely why I suggested Tractive, but oh well. I understand that Europe is a really small market anyways. Sorry for derailing the thread!

This is not the place to discuss the intricacies of our business model but it is certainly not as simple as you describe. Sorry the shipping costs add up. Incidentally there are components used in our Xida assembly from all over the world, including the US, not just Tractive.

I guess Emilio must be sick of answering this question, I asked too....

The cost of Xidas landed in the UK/Europe is pretty painful. The import duty alone was about the same cost of the Meister Rs that everyone in the UK seems to rave about.... But no one is buying Xidas to save money, especially anyone in Europe.

I bought the same spring rate that I had previously been running with Gaz Gold Pros (UK version of spec miata spec damper) and despite no other changes, not even the alignment, I couldn't believe I was driving with the same spring rates and fully understood why those dampers were cheaper than just the import duty on the Xidas.

When you look at what you're getting, you won't find a European based alternative with even a fraction of the development of these. Same story with pretty much every other system on the car too....

And that is the reason why I'll fly 12 hours to pick up my set of xidas. The future wife will have her honeymoon. Win Win.

Dampers were illegal to take in both hand and checked luggage as of 2018.... I looked....

You sir have just saved my ass. Placed my order now.

Not according to carsalesbase. MX5's sold by territory since 1997 (no EU data available pre '97):

US 252,116
EU 294,224

There's a market. Whether any business has the infrastructure, the bandwidth...or simply the interest/desire (whatever), is another matter.

Quick look at the new touchscreen now shipping with all Xida ACE systems. Cool stuff!


For those of you with Ace systems already, upgrading to the touchscreen requires changing the entire harness and controller unit.

Thrilled to see that you are still pushing the envelope!

The connectors to the shocks are different too. They would probably have to buy the whole thing to get the new controller.

Looking for some thoughts on my situation. So my local track is very rough, like, probably worse than you're imagining. The new track toy I bought is a 130whp NA with some whitener racing revalved bilsteins on 700/400 springs. They are way too stiff for the surface IMO. The car is not enjoyable to drive.

I want to go XIDAs, I ran them on my last car out here in the 700/400 variety, because at the time that was the go to. I know that now more people are running 800/500 for 200tw track use.

With 99% of my track time being on a very bumpy track, does it make sense to stick with 700/400 vs going stiffer? For reference the 700/400 xidas were like a cloud compared to 700/400 bilsteins. I'm thinking go 700/400 race xidas and run on the high side of the recommended ride height to keep as much travel as I can. My goal is a fun track toy, not competing, but I also don't street drive other than to and from (15 minutes).


TL/DR, how much does a very rough track impact your spring rate decision with XIDAs?

XL's are only appropriate for taller ride heights that would preclude any rates above 550/350. For track use, just Xida Race.

1. Does street ride quality matter at all?
2. Weight w/ driver?
3. Tire size and model?

1. Nope, is only driven to and from the track since I live nearby.
2. 2358lbs with me in there
3. 205 re71rs right now. Will stick with 205s going forward, likely switching to VR1s for my next set. 15x8 6uls.

800/500 Race with helpers and our sway bar recommendations would be fastest. 700/400 a tad easier to drive but not quite enough rate for those tires/weight.

Thanks Emilio, I appreciate the information

All Xida combinations in stock and ready to ship - we even have a set of NA/NB Ace with the new touch screen controller on the shelf ready to go!
