Need Front suspension advice for my 68 camaro

[Bmf5150]

My car is a 1968 camaro with a LS motor. I'm looking for more modern sports car handling yet with better ride quality than a 68 camaro leaf spring.. I mainly street drive the car and occasionally take to the track for 1/4 mile drag race.. I'm looking at the DSE front speed kit 2 and there four link, or my other option is the ridetech coil over system level two ..do any of you guys have experience with either of theses setups or opinion on which would be a better setup??thanks for your advice..
