Who makes the best (most effective) adjustable torque arm for street/strip use, BMR Spohn or someone else.

 

most effective???

that will come down to opinion. so I will state that I like BMR.

 

Most effective would be any torque arm that relocates the front mount from the transmission tailshaft to some sort of cross brace. Both Spohn and BMR make a quality torque arm that does this.
BMR
Spohn
I will be going with the Spohn simply because its the same thing but it costs less. Plus Spohn has the option for a front driveshaft loop for $40 whereas BMR will charge another $100 for that. Both are good quality torque arms and like was stated already it comes down to personal preference. I say you can't go wrong with either one.

 

The design and assembly quality of the Spohn parts is unsurpassed. Steve Spohn and his dad build them in their own shop, unlike other vendors who "contract out". He's an AWS certified welder and learned an awful lot about suspension from working on his own 3rd Gen.

I've gone with a lot of the Spohn parts, including the torque arm... on which he even relocated the driveshaft loop to accomodate the tailshaft extension of the Gear Vendor O/D unit:

A good friend of mine has a 30th SS convertible that has managed to run an 8.76 @ 160MPH, and he runs a complete Spohn suspension.

Your good friend wouldn't happen to be George Baxter and his wicked 97SS convertable would it?
Just one question, how would the Spohn setup be on a street/strip lowered 4th gen? From the pitcures it looks like it would hang pretty low.

 

The front mount for the torque arm on my setup is the one for the Mufflex 4" Catback. I was running that before I switched to the straight duals. I started with the "standard" mount, but it got a little crowded with the 4" exhuast and a 3.8" carbon fiber DS:

If you get the "standard" front mount, it is about 1" closer to the body, as you can see from the pic above. Shouldn't be a problem unless the car has been dropped quite a bit. When I had the front dropped about 1.8", and the rear down 1.0", the "Mufflex" deep front mount would drag on speed bumps, but then so would the 3" Y-pipe and cats, at least on the driver's side.

Yes.... that would be George Baxter. I have quite a few pic's of his latest mods on this page:

We're trying to get it ready for the PRO/Edelbrock Xtreme Street class..... they are running at Atco (NJ) in 2 weeks.

 

So the spohn torque arm just bolts in instead of welding onto the subframe connectors like the BMR? I would like that a lot better than having someone weld the BMR one in for me.

 

Wait, can someone confirm that the BMR torque arm needs to be welded on? I thought it was bolt on as well. I'm looking into getting a torque arm in a few months and am also choosing b/w BMR and Sphon.

 

Spohn bolts directly to the "pads" for the g-load brace... includes longer, higher strength bolts.

From the BMR web page for the Trak Pak arm:

 

have lots of bmr products but but went with the spohn TA becasue there was no welding.

 

Thanks for all the replys from the info given I think I'll go with the Spohn Torque Arm.

 

Injuneer, Can you please name all the aftermarket components in this pic? http://cjcfo.fbody.com/members/injun.../DCP03545a.jpg Sorry for the dumb question but I want to know as much abour suspension as possible.

 

Red,
From what I see in that pick there are adjustable lower control arms, adjustable torque arm and a drag rear sway bar all from spohn. There are also springs with airbags and what look to be Hal Shocks. Sorry to Injuneer if any of that was wrong.

Injuneer,
How do you like the rear sway? Did you notice any difference at the track? Would it be acceptable on the street? I'm thinking about picking one up when I do the rest of the suspension on my daily driver. I'm tolerant of most parts, but am curious what your oppinion of it is.

 

looks like a 12 bolt too, and lower control arm relocation brackets.


how big of an exhaust pipe is that you got over hte axel there?

 

STuff visible in the pictures:

Suspension/Chassis:
-Spohn race version 1-5/16" solid chrome moly sway bar
-Spohn adjustable LCA's with poly ends (have since been replaced with rod ends LCA's, still adjustable, but without the big ugly nut)
-Spohn LCA relocation brackets
-Spohn race version adjustable torque arm - rod end
-Just Suspension adjustable panhard rod - poly ends
-QA1/HAL adjustable shocks
-Eibach Drag Launch Springs
-Air Lift air bags (have been removed, since the sway bar takes care of keeping the body level on launch)
-custom chrome moly SFC's (tied into roll bar)

Drivetrain:
-Strange 12-bolt, 4.10's
-Mark Williams 3" chrome moly driveshaft

Brakes:
-Baer slotted/cross-drilled/zinc-washed 11.4" rotors

Exhaust:
-Mufflex 4" catback with Flowmaster (has since been replaced with true duals, dumpiong in front of the axle - see 1st picture.)

Fuel System:
-Bosch 500HP fuel pump (2nd pump, for nitrous)
-SX billet fuel filter
-6AN fuel lines

I haven't launched it with the full shot of juice yet, so I don't know how the sway bar will work. It was designed to be "streetable", but I don't really drive it on the street much. I don't think I would push it hard through the corners with no front sway bar, and 26x4.5" skinnies....
