No tubular control arm (that i know of) is going to change bump steer. unless the arms are shorter or longer, as for camber gain the only way to change it is to relocate the control arm mounting point (guildstrand mod on first gen)or the ball joint pivot location so tall ball joints or ATS Tall spindles. you would never know the differance on a street driven car.
have a look at our arms, i noticed you missed them in your product search
