Torque arm vs 4 link ???????

[Just 1 More]

I'm sure this has been beat to death but indulge me. After looking at the displays at the Good Guys Columbus show, What true benefit does one have over the other?
I was dead set hard core going with the TCI torque arm but then realized that future option of adding a Gear Vendors OD might be an issue with the torque arm clearance. So rethinking about doing the 4 link. I definitely want to get away from the leaf springs and go with some type of coil over system. Just a street cruiser that likes to take curves fast. Looking for opinions, Thanks

I chose my watts link specifically because I wanted to be able to change my rear roll center to better suit the type of track I was at(Road course, AutoX, street). The frame mounted watts vs an axle mounted watts means the roll center doesn't migrate with suspension movement which should lead to a more predictable car.

I cut out my triangulated upper 4 link arms, in favor of an adjustable 3 link to eliminate the dual roll center(watts and triangulated uppers) issue. I wanted the adjustability in the 3 link because I didn't know what Antisquat i would need with different tracks.

A torque arm generally isn't adjustable for antisquat, you get what the manufacturer gives you, but I'm betting the companies on here put a lot of engineering into the proper value for your type of car. A Panhard could be adjustable real easy though, so you would have some tuning int he roll center.

for reference, my car is a 69 442. hope this opinion helps.
