Is there comfort Nirvana to be found on Xidas (maybe on 500ish spring rates) or Teins?
Comfort level, I think fm/tokico is high on the list of those. I'd rate them: 1) fm/tokico 2) tein basis 3)xidas (700/400). I haven't tried super low sprung xidas, not even sure that exists.

Of course when it comes to performance, it's:
1) xida
..
..
5) fm/tokico
..
8) tein basis

But for the 1000th time, I'm not a track racer so my experience can only be applied to street cars and never track cars.

Most people seem to revel at Xidas and based on peoples success in competitive events I can see why. From its birth from what 949 talks about it is a track set up with different spring rates available for different set ups ie tire and mainly what type of racing you do.

To me the FM Fox was set up and designed from birth to be the balance between street and track. Since I am going to drive it mainly on the street I want a set up that is geared more towards that. I feel as though the xida is a little more track dedicated yet tamable on the street.

*****My opinion based on my research not fact nor do I present it as such.******

Cause everyone wi th xidas complain about lack of rear travel so they can put the tire in the fender.

If you don't feel like you're getting molested by a buffalo, sweaty, armpit stains, half a 40 in the passenger seat, lit cigarette in the overfilled ashtray, hard rock blaring through the 1 working speaker that's zip tied to a full roll cage, aluminum seats with no padding, 90 point harnesses, and gutted doors with half-gutted dashboard on your morning commute


.......you are a VAGINA
My point was the valving allows them to be comfy on the street with super high rates.

I was just saying that it seems like quite a leap to conclude that buying Fox shocks instead of Xidas is a "really dumb decision."

It's important (for some applications) to note that the Fox setup uses 2.5" springs whereas the Xidas use 2.25" springs. I understand that the smaller spring allows for more clearance, such as if one would like to run 10" wheels, correct?

The Fox does seem like a really nice setup, and I'm sure you'll love them.

Now that he's clarified that its mostly a street car, maybe it's not as dumb of a decision.
But man, since the price is the same, I really can't imagine seeing them on the same level as xida. If they were much cheaper, then we'd have a case. I guess that's why I concluded "dumb decision".

If the fm/tokico combo was say, 1600-1800 dollhairs, I'd never recommend it to anyone. Even on a street car lol

You should know how to set up your suspension with 60000 posts in miata forum so that a custom suspension for a miata doesn't allow the tire to contact the fender

You can get the Xidas with a much lower rate spring if you like, and the dampening can work with it. On full soft (with 700/400 rates) the car rides pretty good but is slightly underdamped.

The Fox shocks claim 5" of stroke (doesn't specify if that's front or rear), to the Xida's rear travel of 4.13" (and 4.8" front travel). That's probably a slight benefit on the Fox, maybe? Dunno.

Anyway, truth is, we'll never actually know which one of these setups is BEST. Xidas, MCS, Fox, Ohlins... There likely won't ever be an objective, independent, apples-to-apples test. So pick the one you like best, and the company you most prefer to deal with.

I am talking to bill of fm at the moment to set up a test between xidas fox and ohlins same driver same car, same tires.
My friend is an instructor at summit I asked him if he was willing to drive them he said yes.

So if I can get goodwin , and 949 to be on board they can use my car . I am willing for them to put a hold on my car for the suspension and who's avg the best times with the same spring rates I'll buy. I will also have video and full write ups.
I also want to test the ride quality with my accelerometer.

Good luck with getting everyone to agree that the test is impartial.

I am sure I can get everyone to agree on terms prior to test otherwise I wouldn't do it.

Highly doubt you'd get 949 on board.

Just sayin'.

Would love to see a comparison done properly though.

Funny you say that since everyone "knows" the Xida's can't be touched. But you are probably right because if all 3 don't agree then no test can be done :(

Are there any advantages to the Fox suspension for a street car over Xidas at all? Say, with relatively soft (550/375) springs and a taller than stock ride height? I'm in a similar boat as OP and was pretty much set to on the the Fox because it sounded it would be more suitable given that the Xida was designed for track use with low ride heights and stiffer springs in mind.

I've heard very similar answers to this.

I just don't see why you'd spend 1800 bucks for a street suspension on the miata....seems a bit overkill to me.

Yeah, basically what Z31Maniac said. High-quality dampers will work well in all situations, and as long as damping range will handle the spring rates, you're good to go. From the Xida product page:

Quote:
  • Damping sweep for front 1000~450 springs, rear 600~250
So, yes, if you put softer springs, the Xidas will make phenomenal street suspension. However, i ask the same question as apexaddict. I truly can't comprehend spending that kind of money on street suspension. I'd go for something that's decent quality but not race quality like Tein Flex Z or the like.

If I can get the same corner speed as the Xida's with a softer spring for the same dollar why wouldn't I use it for a street car that hits the track 5 times a year?

...You ever wonder why Emilio hadn't already thought of something like that?
I can't think of a single person here that would choose stiffer suspension over softer if both performed identically.
