J's racing roll center adjuster?
Not familiar with S's suspension, I am not sure if this is necessary or must for the lowered S or BS?
Anyone using this or sort of this?

From J's racing site
What is roll center?

Roll increased after lowering?

Roll center adjusted?

 

Looks cool! It just extends the lower a-arm mount to reduce the leverage affect of the greater distance between roll center and cg. I wonder how well it will actually work (or if the effect would even be felt).

 

It could have some merrit. A lot of people complain that the car doesn't handle any better when lowered, this could be a potential solution.

 

Looks like 17"+ wheels will be required to clear the new position of the lower arm.

 

J's does not list this for S2000. It's listed for FF cars...

 

Actualy, J's does have it for the s2k

its under S2000 DRIVE PARTS

and u can get different levels of adjustment as well as the whole assembly

 

You're right, I see it now.

 

Hey I wrote that stuff. Notice how the English isn't consistant with the rest of the site.

 

I'd like to hear from the folks wiht first hand experience.
I am curious what the track junkies have to say about this? Speak up guys?! RaceMiata?
Charles, any more insight? Where did you get the roll center and center of mass points from?

 

Isn't this the same thing as a bump steer eliminator?
