custom made RCA question: what height?

[cj]

A friend of mine offered to fabricate a pair of RCA (Roll Center Adjusters). My question is how fat (what height) should the RCA be, having in mind that i'll be installing Tokico HTS102 all around (short stroke conversion).

...or if someone can just measure one's own!

30mm is ok if you shorthen the strut 40mm.

The best way to determine the correct hight, is measuring it. Lower the car to your desired hight and look how much the hub needs to move in order to have the lower control arm perpendicular to the ground.

Measure with the normal # of people in the car and half a tank of gas.

This would give you the best possible negative camber gain.

thanks for the replies! :wink:

I'd say 40mm for a short stroke HTS set-up, since they are VERY short front stroke.

A good rough guide to RCA height should be about equal to or just under the amount you lower the car.

Does anyone know what is the stock position of the control arms? Are they exactly perpendicular? My car came with some changes in the suspension so i can't use its current status as a criteria for the angle.
