I,m going to build another zuk and this time I want to go 1/4 eliptical in the rear, what have you guys used for springs and how many in the spring pack?

RIck, I haven't forgotten you -

I made my leafs from Waggy springs + Wranglers and had a new main leaf made.

I made them with 12 50mm leaves.

thanks guys for your help. that gives me a place to start
