DSE quadra link vs. leaf springs

[syenkoc]

Hello all,

I have a question about Detroit Speed's quadra link system. I'm building a '69 Camaro resto-rod, and I'm debating whether to install DSE's quadra link rear end vs. modern leaf springs. My main concern with this car is drivability - I'm don't really care about originality. (The car is a plain-jane 307, so I don't feel too guilty about hacking it apart and installing modern parts.)

I've heard conflicting reports about just how good DSE's rear end is. A couple of people told me that it significantly increases the unsprung weight and actually degrades the handling characteristics. I saw a '70 Chevelle with some really funky composite leaf springs; the owner told me they weigh about 80% less than steel leaf springs and the car handles like a dream (he also had a modern front suspension, but I'm doing that anyway).

Like I said, the major concern in drivability. I'm going to install a fairly high horsepower engine (my uncle is helping me build a 427 aluminum small block, and it should turn 500 hp when it's done). Any one have any advice/recommendations?

Cheers,
John.
