69 Camaro Front Suspension

[firstgencam]

Ok everyone I am looking at the different coilover setups for the front of my 69 and am wondering which one out there is the best as far as performance, quality, and price. I have a friend that has the DSE Speed Kit 3 on his car which requires a lot of modification to the subframe which isnt that big of a deal, but is it that much better than the cheaper kits out there that are just a direct bolt in coilover system? Like Speed Tech front suspension for example? Any suggestions or comments would be greatly appreciated.

Thanks

Jon
