Whatever happened to the "we have to wait until the last year of production to get CARB approval" line? Seems like the NC requirements just don't apply to the ND somehow. :roll:

I so want this SC.

I hear it is fully contained. I assume this is the unit is bolted on, the belts are reworked, rework the airflow to and from unit, and then change out the fuel injectors. What else has to be done to get this thing to work?

Can boost about 70bhp.

Comes with big 100k mile warranty. 50 state emissions.

Hi Brian. Wondering if you are still trialling the Bilstein B8/Roadstersport Spring combination? If so, what are your thoughts.

It works. What I like is that high speed damping is great, the Bilsteins are firm over minor road imperfections and yet very comfortable over the bigger potholes, etc. You see a serious pothole ahead and do not have time to swerve around it and think it is going to be brutal...but then the Bilsteins just soak it up without drama.

On the other hand, if I am bothering to put in all the time and money for install, most shops about $100 per corner before alignment costs, then I still think I would buy the KONI SPORT shock for more control over the results. As the KONI age you can slowly crank up the damping, with the Bilstein or any other non-adjustable shock you get what you get and cannot adjust as time marches forward. Thus, my choice would always be the adjustable shock so I can compensate over time for wear and have fine control over balance front to rear, etc. But for those not inclined to use the adjustment feature, or their driveway angle would not allow the extra half inch of lowering included with the KONI, then the Bilstein's slightly shorter shock body (for more travel with lowering springs) and more aggressive damping is well matched for lowering springs...which is exactly why they built these shocks. I expect they will do well over time just as our similar Bilstein choice has on NC gen Miata.

But are the B8's, or B9's for that matter, much different form the OEM Club Bilsteins?
And, if used with RoadsterSport springs, would the B8's use the stock or short bumpstops?

^^^ Sorry, that SHOULD have been:

And, if used with RoadsterSport or Progress (ST) springs, would the B8's use the stock or short bumpstops?

The high speed damping is where I feel the difference over the stock Club Bilsteins, which we tested when first developing our springs. You could use stock bumpstops and that would still give you extra half inch of travel but I prefer our short stops which gives a good extra inch of travel with B8/Short stops compared to stock Club Bilsteins and stock stops (I like more free travel before stops which helps the car soak up more road surface chatter without transfer of that chatter through the stops).

So now I'm leaning toward B8's with RS springs and bumpstops as a touring solution, instead of Konis, stock springs, and Progress sways. Wouldnt have to worry about jackdown on those winery roads...
