I really like the look of these but just don't understand how Maxrev runs the car so low and still has enough shock travel especially given the fact that these are stock length shocks. No idea why Eibach didn't go with at least a shortened rear.
I like these but would like to get a tad softer on the rates. Probably something closer to 750-800lbs but that just means I'm going to be even more likely to bottom these out.

The way that someone (away from this forum) was that the Roll-Center Adjusters allow you to regain roughly 1/2 of the travel that these shock/springs typically eliminate.
But my question still is how much lowering of the chassis is to be expected or required for a reasonable handling improvement? Or maybe people are lowering their cars for other reasons and maybe most of the lowering is more for aero or personal or dare I write 'aesthetic' reasons? This suspension system/mod seems like it us engineered for very specific use. And the racetrack people and their counterparts [AutoX-competitors] would maybe each like to believe that this Evasive-Spec-design is more suited to their respective applications, but neither seems proven in my reading - - Comments?
More to the point, is there someone who thinks that only lowering the car about 20mm-front and/or 16mm-rear (from stock] is within the preferred window for performance reasons? Do RCA's seem like a necessary parts to facilitate both the lowering of the car and racetrack lap-times?
Thanks -jeff

The problem is that the Evasive-Spec Eibach R2's do not allow you to adjust ride height and preload independently like the TEIN SRC's do. Worse, the shock length is about the same as OEM, which might suggest that the best ride height for optimal compression/rebound travel is at or near stock ride height. From what I hear, when some users lowered their cars to their desired ride height, some found that they lost more compression travel than they wanted and were uncomfortably close to the bumpstops, forcing them to raise the car back up.
The J's RCA effectively lowers the bottom mounting points of the shocks by 1/2", which lowers the car 1/2" without touching preload or affecting compression travel. That is why Rob Walker (maxrev) is able to be lowered to what he considers satisfactory without running out of compression travel and hitting the bumpstops too early.
The optimal ride height is up for debate, but in general you want to go as low as you can without running into clearance issues and without completely screwing up the suspension geometry (which the RCA's and BSK's are designed to help alleviate). Lowering the car lowers the center of gravity, which is it's main benefit. It also decreases the aerodynamic drag of the car significantly.
FWIW, I am lowered to a height of 3.5" at the front pinch welds and 3.75" at the rear pinch welds, and that is close to what many consider "optimal" in the S2000. FYI, the stock ride height is 4.5" to the front and rear pinch welds. That means I am lowered 1" (25.4 mm) in the front, and 0.75" (19 mm) in the rear. That isn't much lowering, really--less of a drop than a lot of lowering spring kits out there. By no means are we slammed or hellaflush.
Hopefully this is useful information to someone who might be confused about the whole Eibach R2, RCA and ride height discussion.

I finished installing mine and I almost even think the rear shocks are longer than stock. The stock came out easy and the replacements needed more pushing on the arms to get them in. I really wished they would have made it shorter as the car will be at least half inch to one inch lower
Also I am having problems with the front brake line brackets and am about to give up and use zip ties
Would be nice to find some rear shock adjusters though. I do have something in mind. Just haven't tried it yet.
