RCA doubt

[hinachyo]

Hi folks, i have a doubt here about using or not the RCA.
In this moment i have konisport and apex springs (-4mm), but it seems me that the car didn`t lowered that much.
The lower suspension arm is completely on horizontal position, that´s the right position? Do i need to put RCA 30mm or 40mm?
Thanks.

Read about the bump-steer fenomenon (use google). Then drive the car - if you notice it, use RCA's at least 30mm but no more that 40mm (if you lower the car 40mm).

dynamic geometry is a very important element of suspension and you shouldnt underestimate it :wink:

I agree with you absolutely, but i want it to know before i put the car on the road only by the lower arm position.

Put the RCA on, you'll feel a difference. (only if you've lowered the car 30mm+)

Hmm..I once uploaded a picture that showed how negative camber was created during compression. Its somewhere in my image map on the site, but I don't know how to repost that pic.

Basically, horizontal A-Arms are a no-no, you'll get the tiniest amount of positive camber gain during compression and negative during droop. Throw those rca's in there and things should be better.
