im very interested in the "helper springs", my farther got them on his Toyota 4X4, and they improved the suspension heaps from a "smooth ride" point of view. but im wondering if these could also be used to improve handling especially on a rally car, Jamiecidpedro please tell me more about the setup you have and how you reckon it benefits handling, cheers Michael.

p.s. i think were talking about the same thing i.e. coil springs witch sit between the leafs and the body to assist the leaf suspension
