Whats a good 1969 Camaro street handling suspension???

Yeah I want a well handling street car so I'll stay away from ladder bar. As far as a 3 or 4 link, is Heidts the way to go or does someone else prefer another company? I would also like to know a little more about an IRS because I'm sure there is a differential that is made for high HP, but I have not been able to find one. Ive been looking at a Corvette's IRS, but I do not know what those differentials HP are rated to. I know an IRS is priced pretty high. That's why I'm trying to get some opinions. I do not want to regret not doing something I wanted to the car when I'm done. On the other hand, I don't want to spend money on parts that don't do what I would like them to.
