C4 adjustable A-arm

Discovered this while browsing on Ebay. (item#120036018314). I figured some of you guys that experiment with suspension mods would be interested.

I saw those last week on ebay. Pole Position in Colorado I believe, used to sell the same thing for $190. Pole Postion appears to be closed becasue the URL that I had for them no longer works. If anyone knows where Pole Position went, please let me know as I'd like to get a set of these but not for $445.

those look really nice. I recently purchased Offset Lower control arm bushings in an effort to obtain more neg camber. Here is hopefully the link: www.vband.com

I saw their ad in Sportscar. I might wind up purchasing them since I'm in SM2.

been used on circle track cars for eons...visit your local circle track parts vendor...goggle ''adjustable a-arm'' and see what speedway motors has for $90.

the one shown on peebay has very limited suspension travel with the heims in the position as shown, use with caution.

Do you mean suspension adjustment? After all that expense and effort of buying and installing it, you might not get a good range of camber and castor?

no, altho that could be a problem (measure your oem a-arm from the center of the ball joint to the ''centerline'' of the inboard pivots and get a new adjustable arm for the same length)...problem that i was referring to is the actual ''suspension travel'' up and down with the heims positioned to deflect laterally rather than rotate as per the peebay item...heims have a very limited deflection in lateral; many asphalt race cars are heavily sprung and minimal ground clearance and are happy with only 2-3'' suspension travel--that is not appropriate for a vette...movement beyond the range of the ''side-moving'' heim will bend or break suspension components....note that the adjustable arm that ''speedway'' sells (others sell cheaper, shop the miriad of circle-track suppliers) is considered an ''expendable'' item due to the low cost thru those suppliers, and the tendency of circle drivers to use their front wheels as weapons.
