Our New 2012 PRHT SS Project....

[Brian]

Who makes these new braces?

Not under any brand currently, something we are considering having made for us.

Customer Paul Young's 2014 MX5 Club following the formula of this project, got the works today, including our Progress Springs and Progress Sways and RoadsterSport Ceramic Street Header, RoadsterSport Midpipe and RoadsterSport SuperQ exhaust...and IL MotorSports rear butterfly brace. Starting heights 14.25 front and 14.5 rear ....and final heights 13.5 front and 14.0 rear. Looks awesome, sounds awesome!

And the very next day....same Progress Springs but SOFT TOP version of same Club version MX5...and same results on heights....13.5 to 13.7 front, and both rears at 14.0

Might seem like a easy question but how do you measure the ride height? Just had Progress springs installed and I'm curious.

From center of the wheel to top edge of the fender

Thank you

Your welcome. As far as i'm concerned that's the point of this forum, to share advice with others that may we have learned or stumbled across before.
Anyhow if you want to be really accurate you can measure your rim diameter first, which if oem 17" wheels should be 18.5". Then measure vertically to the fender lip from the bottom of the rim and then take away 9.25" or half the diameter you measured if other sized wheel used.

Did the SS Project car get shorter bump stops to go along with the lowering springs?

[Brian]

On this car we left the full length bumpstops...and that seems to work very well with the factory bilsteins and Progress springs. If we used KONI shocks that lowers the car ANOTHER half inch and these stops would then be too long (you would ride them all the time). Thus, if adding KONI with these springs, then add the FCM stops on our site for "Lowered" cars....which are shorter stops.

I was driving this car last night and impressed once again how "RIGHT" this car is, the ride is amazing, the handling around freeway on-ramps is AWESOME, and the SOUND is glorious... and extra torque is felt everywhere. My wife doesn't want me to make any more changes, she really loves it as it is....and I agree it is a really sweet Miata, the factory should done it this way.

Thanks for noting this, Brian.
I followed your emailed advice when I placed my GWR order of Progress springs + KONIs and also ordered the "FCM 36/58 White Bump Stop Kit SPORT", in May.

However, when I picked up my car from the auto shop, I was confused by the installer reporting that they couldn't use the FCM Stops: "they did not fit with the KONIs and had to use some OEM hardware & some KONI hardware to make it all work while reusing the OEM bumpstops".
I asked if they trimmed the OEMs down then, so that they were not riding on them all the time due to the lowering? No, they were left at full length.

So I suspect that the car is riding the bumpstops all the time now.
Does it mean that the shocks are barely able to do their job; that all weight is on the springs and would float around like a "boat"?
What would that feel like on the road?

I think I may find another shop to re-check & re-install the KONIs to be sure.
Too bad GWR & Rocky's is really too far from Chicago for a quick road-trip.
