My overall initial goal for the car is 10.80's with 60's in the 1.4-1.5 area , after my NA combo is dialed in I do plan to run a 150 shot on top of that . Car will be street driven but not daily driven , I will have a spooled rear so that tells you what my threshold is I like the design of the spohn arm alot . With that arm there are a couple things I dont like though . 1 being its weight , 2 ) I have heard of a few exhaust routing issues around that beefy crossmember . I havent really decided what to do for an exhaust since the Torque arm design seems to dictate what your options are . I have also heard with some of the faster cars with tranny crossmember mounted TA's( not necessarily the spohn arm ) putting stress cracks in the floor pan on either side of the frame rails over a period of time .
My other option is to run a BMR X-treme duty arm ~or Madman arm . Both of those arm utilize a tubular moly crossmember that mounted in between the subframe connectors . This route will take some Fabbing though as most 3rd gen subframe desings wont facilitate this type of crossmember . I did find that if I use Southside Machine subframes though this type of arm will work , because they are boxed and travel along outside of the car .
So , what are you guys running . Do you like what ya have . Any thoughts on any of this would be great

it works and it doesn't break. The SAM car has one and is going 9.80s on motor with 60s in the 1.3 range on a JERICO

FACE IT

its cheap and it works

Colonel also runs one, 9.80s on motor and the torque arm is in the STOCK LOCATION too

But if you MUST HAVE the trick torque arm heheheh.......i like the billingsley one the best

 

how much does that Random Tech unit go for? I've been looking into several different brands of TA's , but haven't seen this one yet...

A guy I know recently sold his 98 Z-28. The car had a 383 LS1, not sure how much nitrous, it was T56 originally, then auto, had BMR poly-bushed LCA's, panhard, lowered to 4" of ground clearance with cut springs. I'm sure I'm leaving stuff out. Anyway, the car ran 11's on motor all day long. I'm can't remember what he ran on the bottle. He broke a Spohn torque arm and went back to using the stock one. He consistently pulled 1.4, 1.5 60ft times. This guy has had that car, a 7 sec strip car (maybe 2?), and recently built a low 11 sec 347 mustang. He builds his cars himself and really knows his stuff. Anyway, he recommends the stock torque arms. Just something to think about.

EDIT: On the other hand, the stock torque arm may hold up better to the LS1 powerband, 383 or not. But that doesn't explain how the Spohn one broke. NOTE: the point of this is not to rip on Spohn, as he has great products and has given me great advice. Shoot, I'll be buying some of his stuff for the RS I should be getting this weekend.

 

Along with others on this board, I've been really happy with my Spohn torque arm. I must say though that I don't drag race my car. I prefer to turn corners.

I feel I should also note that a buddy of mine has snapped two Spohn t-arms doing high RPM launches with is 305/T-5 IROC that was pretty much stock. Steve has been great though and replaced both arms. Why they broke I can't say. It may have just been a fluke thing.
