Torque Arm vs 4-Link

[AEH]

I have a question regarding which suspension type is best for me and how I plan to use my car. I have searched this forum and every other resource I can find, read every article I can find but still have found no definitive answer to my question. IF there is, please post a link. I've think I've read everything David Pozzi has made regarding suspensions and have not ever seen it addressed from my perspective. Every discussion I read is coming at it from the "what suspension performs best" perspective, and there is not really even a consensus there either. First a little background.



I have a 69 Camaro I am getting ready to start building. My buddy had the car for the last 15 years sitting in his barn and finally agreed to let me have it. He had already replaced all the rot so it's a good solid body to start with.
I bought a Crate LSA and don't plan (at this time) to go much over stock. I'll make a few tweaks, Maybe 650hp at the motor, but pretty tame on a relative scale. I have a New Vintage Racing sub-frame fully dressed with all new parts, ridetech Adjustable shocks, Z06 big brakes, etc. I picked it up from a friend, $4000 was where I couldn't say no. (so there goes the Stick with one vendor front & rear argument) I may not use the big brakes if I decide on 17" wheels (for more sidewall) but right now that's what on it. The ridetech's have 500lb springs and I'll probably reduce the rate for a smoother ride too.

I'm not exactly sure how to put this so this thread wont take a tangent, but here goes. My intent for the car is to build a very nice cruiser we can drive anywhere we want to go and still enjoy the ride. I don't want to be cussing it after 8 hours or have to argue with the wife whether or not we take the Camaro on the next trip. I realize everything is a compromise but I want all the performance I can get without sacrificing ride. I will never track the car and it'll never see the drag strip. I want it to be fast and capable and there will be times I'll push it, but I'm not trying to win any titles or even compete. It's just gonna be My Car. I'll get the best seats I can find, use all the sound dampening and Insulation I can get in it and probably soften whatever suspension I end up with.

So now my question. Which is better suited to meet my needs, Torque Arm or 4 Link. Again, a Smooth, Quite and comfortable ride is my top priority, but I want all the performance I can get with that in mind. I think I know whose 4-link and whose torque arm I like best, so I'm not trying to pick a vendor, I'm just trying to figure out which Geometry/technology is better for me. Either would certainly meet my performance objectives. I do realize I just made a pretty good argument for Leaf springs, but there is not any wow factor in that. No Offense to the guys running mono leafs, that's just not what I'm shooting for.

Let me try and stave off one of the typical expected comments. I realize a 69 Camaro will never be a 2020 Cadillac or a BMW. However, I do think we can improve on both ride and performance and If I wanted a Cadillac, I'd get one. Frankly it would be a whole lot cheaper, lol.

I know this was a little long winded, but I would appreciate any input and I hope I didn't come across as anything other than sincere. Mike
