Ran through a few tests with the Street Spring Pack to see how they behaved when deliberately bottomed. This is hitting huge dips and lumps in the track with the car too low and shocks set full soft (20 clicks). Bottoming was controlled and not harsh. Too abrupt as you might imagine but this is to replicate worst case scenario. Dial up shocks halfway to full stiff (10 clicks) and the car was surprisingly fast, bottoming gently on the biggest yumps as they should. Had a 1:26.9 on predictive with 225 Conti ECS but flubbed the last turn so just a 1:27.1 CCW. Still mighty quick, balanced and fun while still having a better than OEM ride.

Next up was the Race Spring Pack on a few different tires, 255/40/17 RE71R, AR-1 and R888R. You know, we really dislike the R888R. That tire does nothing well. Ran the car down to about 137mm pinch weld F&R which is equivalent to about 130mm on OEM size tires (that's low). Too hot to lay down any fast laps but still managed a 1:24.17 in there somewhere.

Same behavior as last test which we did at taller ride height. Down low, the transitional response improved and a bit less dive under braking. Depending on track roughness, we'll probably recommend 130-135mm ride height for smoother tracks and 140-145mm for rough tracks or dual duty. One other detail which is important to us is just where in the shocks adjustment range the car works best. We don't want to need to run full stiff or full soft just to get it to work. We also don't want front and rear wildly different. Either just indicates the useful range is wrong. Rough tracks should be somewhere in the middle settings, going stiffer for smoother tracks or Hoosiers or big aero.

This testing all with the 22mm front bar and Roll Center Adjuster kit which we have settled on. Both will be added to our website shortly. We offer a BGK (Big Grip Kit) for the early Miatas that has all the bits we recommend to get a completely tuned suspension system. This saves having to piece together various bits without knowing how they will work together or how to set them up. We will do the same for the 86: A complete hardware package with every part you need and baseline alignment settings for street, dual duty or competition published on the website. Basically replicating what's on Blub. So one can order just the Xidas to work with what sway bars, links, alignment they have or if you want a carefully researched and tested, proven fast setup in one go, BGK.

Pumped for this!
