Roll Centre Adjuster

[Skym]

Anyone tried a Roll Centre Adjuster on their Skyline???

Roll Centre Adjuster makes the lower arm straight when car is lowered and supposedly increases stabilty and corner speed.

The only thing really bad about those it the massive amount of camber gain you will have. I wish some one would make an upright that had the wheel bearing moved up on it that way it would be closer to stock geometry but lower. Maybe i'll have to make some thing like that, or some thing.

I've got a machinist that can do custom billet uprights if you guys want 'em.

i got adjustable FUCA, so added camber from the RCA isn't an issue

No static camber is not the issues its the camber gain that you will have as the wheel moves vertically and thinking about this a bit more it might give you more bump steer as well....

Bump steer is caused by the tie-rod not being straight. The only reason you put roll center adjusters is cause when you lower the car the distance between the roll-center and the center of gravity becomes larger. This causes body-roll (since the moment between them is bigger). You can get rid of body-roll by putting aftermarket sway bars. Also if you put a cage in the car it will help get rid of body-roll. Same thing with strut bars, it will get rid of body-roll. The roll-center adjusters are just another way of fixing the problems caused with lowering the car. I haven't seen too many race cars with roll-center adjusters (by race cars, I mean production cars made into race cars). Also these race cars aren't lowered that much either.
