    not really, usually you know how much you have to raise a car by to make it about level with the axle... i guess get under your car with a measuring tape?

    i had the understanding, the amount u lower the front by is approximately how thick u need the rca
    since the lower u go the more the lower arms will become level with the ground

    so if i lower my hachi 50mm (soon to be height), i should use a 50mm RCA? and where are these measurements (50mm RCA) taken from?.. im pretty sure the guy who had my car before me had it lowered 50mm, and had 30-35mm RCA's...

    ????? any help???

    The place to measure is the end of the control arm that connects to the bottom of the strut tower. When you lower your car the control arm will move from roughly parallel with the road to point up from the road. Now the measurement that you want is how far the outer part of the control arm needs to move down to once again be roughly parallel with the road. Now it doesn't have to be perfect but if you are getting custom ones made you may as well get it within 5mm or so. I think that a little shorter than needed is better than a little too long.

    Hope this helps.

    I've done the Sigma arm swap.... total cost of $55(arms & tie rods). +wheel alighnment.

    Result: -3 degrees camber both sides. I find steering alot easier and responsive.
    Had to flare guards to fit 15 by 7 longchamps. Visually: track increase and camber differenace is very clearly seen.

    i've attached a pic. Longchamps aren't fitted. Rims in picture are 15 by 6.5 (25 offset). At that time the guards didn't require flaring.
