Echoing what others said, it's silly to spend $1500 on suspension for a Miata. You're better off going with a budget Bilstein setup, or spending the $2k it takes to get the Xidas.

You also don't NEED the helper springs (and can add them later on too). The Konis don't have them, so apples the apples the Xidas are only $1800 including new NB tophats.

I have track experience but i've only been on track 4 times plus a couple AutoX events. All the track days were in my dad's car though so I've never been on a road course in a miata. I'm seriously debating the Xidas, I just have to see if I can come up with the funds.
Yeah I was talking about Koni Sports :ugh:
Right on, I'll probably just end up going with Xidas after hearing what everyone is saying.

That's a good point, plus I already have NB tophats so more like 1700 :)

Definitely get the helper springs.

You can see in videos of Xidas while on track they are doing their job. If you decide not to use them the main spring will come unseated when going over large bumps or rumble strips.

If you already have NB upper mounts then that saves you a bit of money and gets you below the $2k mark at least.

That's true, but I live in california so tax is going to be almost 200 bucks :yippee: But yes, I definitely plan on getting the helper springs.

Sure, helper springs are a good idea and worth it. I was just saying that without the helper springs you've got more of an apples-to-apples comparison, and you'd be better off going with Xidas without helpers over the Koni setup.

And oi, that sales tax tho...

Yeah dude, sales tax is a bitch. Especially with a 2000 dollar purchase.

Welp, you guys have convinced me. I'll be ordering the Xidas tomorrow with the helper springs and 700/400 main spring rates. I was speaking to Emilio for a while, and he was saying that the 949 sway bar combo is highly recommended seeing as I'd get a lot of over steer with my current sway bar setup (FM front and rear). He said I could temporariliy drive with the stock rear sway bar and the FM front sway bar. I was wondering what sway bars you guys are running with your Xidas and how you like them?

FM front with stock rear will be fine - it's gonna be such a huge improvement I wouldn't stress too much about having the sways yet - you can pick them up at a later date.

The FM front bar + 11mm stock rear and 700/400 springs gives you a roll stiffness of 3577 lb-ft/deg vs the RB 1.125 & MSM 14mm bar (the 949 combo) and same springs gives you a roll stiffness of 3882 lb-ft/deg: ~8% difference.

(for comparison factory springs + sways is somewhere around 1000lb-ft/deg)

Oh damn, okay that's comforting. He made it sound like I needed to get them asap. I still plan on getting them but I guess it's not as high of a priority anymore. Thanks for the help guys, I'm insanely excited to get my new suspension all set up.

Well he'll know better for sure, but it doesn't seem like there's as much difference between the sways as there will be the shocks/spring rate so you might as well do the thing that will make the most difference first.

Probably depends a lot on what tyres/usage too.

Yeah that's a good point, right now I'm running with Star Specs (TW200) but I plan on trying out some NT01s next (TW100) so I'll make it a priority to get the sway bars first. I really wanna get those coaxial billet mounts as well. I thought I was almost done putting money into this car for a while but we all know that's never gonna happen with any of our cars.

I'd just save up and go without NT01s. What wheel size are you running? Tire size?

Save your money on a hard compound like any of the Toyos (outside of the RR) or the NT01 (technically a Toyo), and just run your Z2s and go to R-S3s on a 9" wheel with the money you'd be spending on a 100TW. The difference in lap times between something like an NT01 and Z2 is about 2 seconds on 2 minute course, and you're just getting Xidas, so trust me... you have plenty of time to find out there without going to a dedicated R comp.

I was wondering that as well. For what purpose are you going to NT01's? HPDE trophies? Or are you going to be doing some sort of actual competition?

I'm running 15 x 8 +28mm off set and I'm running 205/50/15 star specs. I'll be driving the star specs for a while since they're fairly fresh but in the future I really would like to experience a properly set up miata with 100TW tires.
No competition or trophies, just interested to see what they're like. Hopefully i'll be competeting next year in some autox events but we'll see. I enjoy road courses more for obvious reasons but autox is much cheaper seat time although they're obviously two different categories of seat time.

Autox is a cheaper event, but usually not cheaper seat time ($50 for 5-6 minutes of driving at an autox, vs $250 for 1.5 hours of seat time at a road course HPDE).

But I get what you're saying, indeed.

Good point, but last autox event I went to there were only 4 other people besides me and the the instructor. We got an insane amount of seat time although it was 75 bucks. This was on Easter though so that probably won't happen again unless it's on another holiday. I could've potentially gotten 5.5-6 hours of seat time but I only got about 3.5 hours since I wasn't out there constantly. It was a great experience minus the fact that my battery got overcharged, heated up, swelled up, vented, and spewed battery acid in my trunk.

Just ordered a set of Xidas with 700/400 rates plus the helper springs. Now I just get to sit here waiting very impatiently for them to come.

You will not regret it.

Oh I bet, only thing is I'm gonna have to wait about 2 months to get the sway bar kit but i'm sure it'll be fine for the time being.
