Experience with truckarm (or centerdrive) style rear suspensions???

[atomicjoe23]

Does anyone out there have any experience with a truckarm (or centerdrive) type of rear suspension. . .especially as compared to a 4-link or 3-link setup using a panhard bar or Watt's linkage and also compared to IRS.

I have a '67 Pontiac Firebird 400 that I'm getting ready to start a Pro-Touring build with and I'm trying to decide what I want to do with my suspension. The truckarm seems to have some pretty good pros to it from what I have been able to dig up and the price is much less than an IRS or 3-link and Watt's linkage and almost exactly the same as a 4-link suspension.

I haven't had a whole lot luck finding many opinions on the truckarm suspension thought besides from Hot Rods to Hell who make the system.

Thanks guys.
