Shock dyno charts for Xida.
Looking at the charts on the 949 racing page, it looks like making adjustments to the single adjustable shocks has a negligible effect on shock compression with the fronts having adjustment range between 150 and 165 lbs of force at max piston speed and the rears having 150 to 180 range with the lines pretty close together over the entire piston speed range... but the same adjustments make a huge difference on rebound! On the rebound the range is 380 to 630 on the fronts and 355 to 705 on the rears at the same max piston speed, with the lines diverging rapidly over the entire piston speed range.
The double adjustable have a similar rebound section of the chart, but the compression has much wider range of change than on the single adjustables.
Now that I am researching this stuff I wish they had charts for the triple adjustabls!
Let me know if I am all fucked up like a soup sandwich here

Generally, a single adjustable shock is just supposed to adjust rebound; that's what makes it single adjustable. Adjusting compression with the same **** is called crosstalk and it's undesirable. In the Xidas, it's there intentionally to allow them to handle a wider range of spring rates. Koni Sports, on the other hand, adjust rebound alone, so they stiffer settings are useless: to much rebound for soft springs, not enough compression for stiff springs.
So yeah, they're working as intended. Single adjustables adjust rebound, double adjustables adjust rebound and low speed compression, and triple adjustables adjust rebound, low speed compression, and high speed compression.

What is the new sweep of spring rates these can run? 350-1000?
You can always have them revalved by HVT, who valved them in the first place, and have them put the latest and greatest AST piston in there. I believe that the XidaS was non DDV valved? so you could always upgrade to the DDV piston. Then again you should probably upgrade to the latest Xida Gen 2 and sell your original set Remember the Gen 1's are AST manufactured, spec valving/design by 949racing named Xida, Gen 2's are a different company, spec valved/designed by 949racing named Xida Gen 2. Its like the NB to NC progression, not much the same, both great cars.
Really? Been dealing with specialty boutique shops much? Probably should have left that $5-600 coilover on there until you got your new set?
EDIT: No affliation with 949 what so ever, none of his parts are on my car currently, never met the guy. That said 949racing has done more for the miata track community in the last 7ish years than anybody in the last 25 years of the car. He is a small specialty shop trying to get large companies to take his "small" orders seriously and in a timely fashion while delivery a quality track product. He is one of the only companies to actually track beat the **** out of his products before offering them for sale. Emilio will often come off as a dick in type and in person, he is not trying to be, he is just very factual, non sugar coat, straight to the answer. No one feels sad for you that you have to wait for your ubber bad *** shocks, so cry to your lover instead. You could always cancel your order and get something from ebay...lol

Just put my old Koni setup back on the car so I can start driving it in anticipation of an event at the end of the month.
I'm #1 on the list (according to Emilio), but still planning for early June.
Things are happening fast though. Shocks at AST mid-month (week and a half away) then to 949 then out to us over the next couple of month or so. When I talked to Emilio, I could hear giddiness in his voice about the Gen 2s. They're going to be great. I'd guess in 3 months time we won't even remember there was a delay.
Excite!

I fully understand what he has does for the community and some things are out of his control (supplier issues.) I run tons of his parts and have been very happy with all of them.
It seems like, all of his parts he only sells what he has or what he will have on hand besides Xidas which are ordered the month before then sent out the next month it's been like that for awhile. I anticipated march. so I sold my current suspension because the racing season in the Midwest doesn't start until May so I figured I'd be fine. There were supplier issues and orders kept getting pushed back... so there's a back log.
I had the option to cancel but then what? My only other option was Ohlins raced valved with swift springs for another $500. Not really proven and a month wait.
Emilio left me a VM today should be a few weeks I'll have them. Can't wait.

HVT put digressive rebound pistons in a set of 5100s (XIDAs) for me last year. It ran me about $1200. Definitely cheaper to sell your Gen1s and buy Gen2s, not to mention all the other benefits the Gen2s have over revalved Gen1s.

Thanks dick.
