torque arm set up or 4 link set up for rear suspension?

[71maroesteban]

Okay as I'm getting closer and closer to ordering a new rear suspension set up I keep looking back and forth from ride techs stuff to speed techs stuff. I'd love to hear some feed back on the two also I know ride techs 4 link will work with the dse mini tubs would the torque arm set up also work with it? Thanks also the car it is for is a 1971 Camaro

4-link. Proof is in the results.

I wouldnt say prooff is in the results..
its all mainly about driving skillz, MP proved that time and time again
The other aspect is which is more common..so will be flooded in results
when you say 4 link, you talking about Triangulated or parallel?

for a camaro, wanting something bolt-on I'd go BMR torque arm..if thats not a worry I'd go AME 3-link

I believe the ride tech 4 link is to triangulated. I see that people with the ridetech post better times I just like the idea of a torque arm with the Pan hard par keep the rear end in place

[Nothingface5384]

you're probably right, I just know for the universal ridetech system you may get either,
Speedtech is a torque arm with panhard bar, with articu-link arms(like DSE swivvel links)
BMRs torque arm looks beefier, and uses the better Watts link setup with theirs
..think their trailing arms use heim joints, but don't quote me on that

BMR torque arm is totally bolt on, welding optional
speedtech you'll need to whip the wlder out

I understand the speed tech torque arm requires no welding to the actual car but more just brackets to the housing which won't be a problem since I will be ordering a new rear end and would have Moser weld the brackets for me. I know bmrs set up and have considered it but can't really find anyone that runs one and is competitive since it weights a lot more

This probably needs it's own thread but...
When you talk about "better times" and "competitive", what venue are you referring to? Is there a class or format that the PT community views as the proving ground for all these bolt on "mods"?
Im my world you roll 3000# and 5 liters through tech @ SVRA. What's the PT equivalent?

Just to clarify
you will need to Weld 1 bracket into the car, the rear shock mount gets welded in, We feel it is just a better way to go, the frame rails are really light gauge steel, we even supply a reinforcement plate to beef it up. Our torque arm is about 1/2 the weight of the other one mentioned and will make routing exhaust MUCH easier. The MOSIER third member is NOT compatible with our torque arm as they decided to machine the pinion mount bolt holes at a different clock location than the original Ford location. Strange center section does work. We can put together the 9" rear end with the brackets installed with 31 spline axles and a center section, either Strange S case or Ford Nodular case TruTrack for 2995.00 you can get a super low ride height NO Floor modifications and full 3" tail pipes

What's the PT equivalent?

everything, SCCA CAM class, USCA events, Goodguys, Run to the(events), Amercan Auto X, LS fest

[wendell]

Gotcha but none of those events have any rules.

I see will the torque arm work with the Moser 12 since that is the one I'll be going with?

[Schwartz Performance]

Gotcha but none of those events have any rules.

Have you ever run any of those events?
200 treadwear tires is a rule.. And a big limiting factor. We all run together at these events. Us, ridetech, DSE, were all up there for times and I believe we all have triangulated 4 link rear suspensions. That's what Esteban is referring to for the quickest times..

ha ha ha ha they have rules. they just make them up as we break them

The Mosier 12 bolt WILL WORK. I can supply one with the brackets installed( you see Currie uses the Mosier 12 bolt center) then the brackets are installed prior to straightening and housing end install to ensure it is straight. Just an option to make your life EASY!!!

NO DOUBT. "My Race My Rules"

I haven't. Like I said, group 6.
Competitive TA cars were built with 3 links, 4 links and torque arms from the mid 80's through the '00s. That's w/ a stringent rule set. Top teams with in a few HP of each other. Spec tires... Seems it wouldbe impossible to make distinctions with "200 tread wear".

[Nothingface5384]

So out of curiosity, what does the speed tech torque arm setup weigh?
And always.wonder how much said setup can handle I'd imagine and easy 1k hp?

[sheck44]

I dont race but I LOVE the handling and ride on my 69', and the guys at Speedtech are great ...

Seems to me that a "bolt on" torque arm would have less compromises than the "bolt on" 4 links. But if I wanted to ditch the leaf springs, I'd get in touch with Mark Magers and try to find an LD 3link. His piece was really well thought out.

it was a great setup and can be made to work well, it was the money factor that killed it for most, if I remember, it was around 6000 dollars for the Lateral Dynamics setup, I was lucky enough to work on some LD equipped cars and I do know there is a shop out (in California) there that has replicated the LD setup directly off the original design plans and has done some tweeks to make it better, right now he only makes them as one off's builds no retail package....rear suspension for 6000 bucks and no shocks with that!! you can do a lot more of the car for that....hell for 5500 bucks you can do our whole Level 3 Coil over system thats the front upper and lower control-arms, a rear tri-angulated 4-link, and 4 triple adjustable coil-overs, front sway bar, tie rod sleeves
