XIDA Club Sport

New for 2011 is the long awaited and more affordable version of the highly sought after Xida coilovers. What did we take out? Nothing! This is the exact same damper as the Xida-S, double and triple adjustable. The difference is we adapted the front shaft and shock body to be compatible with the low cost but very functional OEM Mazda 99-05 upper shock mount. This and the success of the original Xida system has allowed us to slash the price down to $1799 for the Club Sport.

The exceptional valving sensitivity produces both incredible grip over any paved surface and exceptional ride quality. Make no mistake, despite the surprising streetability, these are purpose built racing dampers intended for use under the most demanding motorsports environments.

Confused about ordering?

Sorry! If you have a 90-97 Miata and do not have factory NB mounts and hardware, you can just add them to your Xida Club Sport order for a complete ready to bolt in system. If you have a 99-05 Miata or the upper shock mounts from same, just order the Xida Club Sports without mounts.

For race tired cars with track performance as the main goal, we generally start with 700/400 rates. If you all of your local tracks are really rough and bumpy, then drop to 600 or 650 from and 350/400 rear. If running 275 Hoosiers on smoother lots or 225/45's on 9" wheels with noticeable aero downforce, 800/500.

For a mostly daily driver that only sees occasional autocross or track use, 550/350 if using really sticky street tires. For medium or small (205/50 on 15x7) street tires on a mostly street car, 450/300 rates. If running an LSx conversion, sames rates apply. If running a small block Ford conversion, add 100# front and 50# to each recommendation range. If you are still not sure, give us a call. We'll get the system matched exactly to your needs.

Discuss...

 

This is very good news for me.

 

 

Hmm, this makes my choice a bit more difficult.

Does anyone out here have the double or triple adj Xidas?

 

Very nice. I know some people who might jump on this. He is going to sell a junk load of these at that price. Go Emilio!

 

That price still makes me look poor. I hope 2011 is a good year... Because I'm getting these, regardless. I need those XTRs first

 

Anyone know what purpose the double spring serves?

I'm also wondering if there are cheaper top hats then 200$

 

doesn't hustler sacrifice babies for these?

 

You can get top hats through mazdaspeed for cheap if you race. The helper spring just keeps the spring tight at full droop, not needed.

 

Dual springs are essential ingredient in getting them to work the way they do. That they keep the springs from rattling is a bonus. Will go into more detail when we officially launch them.

 

They're just about the same price as the twin-tube inferior competition, better in every way bar none, and you can get them revalved almost anywhere and they're essentially brand new.
You probably won't find one cheaper that raises the mount point for the rear. He also sells them cheaper than AST sold me the spherical uppers. When you have the spherical upper and solid/metal lower mounts, even on the 20-year old rubber bushings) I had an incredible amount of surface feedback.You can really feel the slip angle on the tire.
Think "inter-species" rather than human sacrifice. I have a different shock that is very similar but only rebound adjustable and a few other features that I don't understand didn't make it to my shocks.
I don't run the helper spring because "I spent enough money that day".
These shocks are going to CRUSH the market. I guess I'll put my spare set of Tein Flex on my daily now since no one with sound mine would purchase them.

I said this on the other forum, and I know I jock these a hard and for no reason, but these dampers are incredible. I put them on my car and immediately dropped 2-seconds. Once I learned to turn-in earlier and learned to use the extreme increase in entry and apex speed, I dropped another .5. The first few sessions, the increased entry and apex speeds feel alien, but the grip is there; I've gone through the grass enough times at Hallett to know that I was entering with more speed and turning in too early to do that on the old shocks.

It was interesting to see suspension attract a crowd of civilians and SM drivers. The coolest part about these is getting an $1800 damper, springs, mounts, and all the leg-work done on valving, while you get the similar/same materials and design, and the same internals as what you'll see Grand Am Sportscar running next year with a tighter seal to extend road-grime durability.

ok, I'm done now.

 

Speaking of unsound minds, hawk them on Clubroadster.net. There are guys there that think Tien Flex's are a lifestyle choice.

Flexes might end up on my car, but it's more because happenstance is a way of life.

 

Emilio,

Similar pricing, can you compare/contrast the differences between the Tein Monoflex and the Xida Clubs? Construction, performance, durability, etc.

 

Wouldn't it be nice to happenstance your way into a non-shitty set of mono tube shocks.

 

it would. but that's not what happenstanced. for my needs, teins are great, ive driven on a few cars with them and had little complaints. I have a DD so i mean...

 

Since these are being toted as the best things since sliced bread, how do they compare to other high-end offerings from companies like Ohlins?

 

i would imagine that they would be a little better due to the fact that the ohlins didn't get a true track miataphile to r&d the valving for a year before closing in on the sweetspot. in laymans terms: the ohlins were jessica alba giving you a bj in the elevator UNTIL.... the doors opened and you were interrupted. =(

the xida's are same situation, but the elevator stopped between floors and you were able to *** in her mouth while she jiggled the *****!

the ohlins are "almost" there. the xida's finished!

 

before or after she got preggers?

 

I'll be damned if that doesn't make me want to try out a set of Xidas!
