rear suspension set up advise

[lang williams]

I'm thinking of redoing the rear suspension of my cobra. I have the summit racing control arms an roush lowering springs an koni yellows already but yet to install. I want a good handling, decent riding street car that sees the strip 2 or 3 times a year. I've been reading up on the steeda 5 link, MM coil overs an IRS swap. This is a weekend cruiser that gets limited strip use an occasional back road blasting. should I stick with what I got or look at the other stuff? I'm also considering the MM front an rear coil overs. I could sell my roush springs an get the coil overs front an rear for the cost of the irs swap or 5 link. advise? thanks.
