Aftermath of stock torque arm after 315 DRs

[HoLLo]

Well, I got my new C5 DD wheels with some Toyo 315 drag radials mounted last Thursday. That night, I took it out for a test. I did some dig launches on a dead street, only trying like 2.5k-3k rpm launch.. The next day driving around I notice a lot of loud clunking when I hit a bump. I thought my wheels/tires were hitting the bumpstops.. So I install some ARP wheel studs and 5/16" spacers (which I planned to do, anyhow).. I take it for another drive, and still a ton of loud clunking..

So today I look up under the car with the plan to tighten every bolt in the rear suspension that I see. and I find a busted torque arm... I never had these clunks until the first night with my 315's, so I guess it was it's time to go. I guess it's my time to go ahead and get a UMI tubular torque arm. Should I get an adjustable or not?

Oh, and before anyone says it. I plan to have the rear-end rebuilt with a new pinion seal this year :cheers:

That generally happens if the bolts were loose at some time and driven around for a while til retightened, factory or non.....
I would get an adjustable unit weather you get UMI,BMR,Spohn its up to you

[96LT1355Z28]

^^ Agreed, go adjustable.

[HoLLo]

Also I think I'll do a stock length torque arm with the relocation bracket.. Any opposers?

[Chris]

Thats what I have on my car.

I know its costing you money, but I have to say NICE!!!! :claps:

How do you like the Toyo DRs


I would go with the adjustable, you never know if you change plans with the car, and may end up needing it.

[HoLLo]

I love the Toyos! I've never had a 315, or a drag radial, so this is my first time with a real tire. I have not found an issue with traction yet! I remember a few weeks ago, I did a 40 roll against another car, 1st gear just spun like hell, 2nd gear spun and slid a bit before it grabbed. If I do a 40 roll now, it hooks like hell and goes! I feel the car torque twist when I hit 2nd gear now. I feel some SCF's needed soon.

whatever you choose,remove TQarm from tranny:hail:

[HoLLo]

Should I go with stock length and relocation bracket, or tunnel mount? Pretty much they'll both do the same thing, except the tunnel mount can be done a little cheaper..

[96lt1m6]

Either way, tunnel mount or relocated mount will help traction....
If it was mine i would use a tunnel mount

[MeanGreen94Z]

if its a DD get the full length relocated arm... mine clunks, which i dont car nor does it bother me but other people hate the clunks... get whatever you prefer but that is the best bet

[BOOSTNU]

Either would be good get it off the tranny b4 that happens to it.

[dsmawd350]

the tunnel mount is more for a drag car. its gonna add more vibration and noise to the car. if you dont have big plans for the car a stock length with a crossmember relocation mount should be fine

[vetwnab]

I vote for stock length with relocation bracket as well.

[QC97Z]

I vote for tunnel mount adjustable. I love my UMI unit. A unit with a driveshaft loop might not be a bad idea either.

Found this on Tech

I have the umi adjustable and I love it. I'm also using the relocation crossmember to take the stress of the tailshaft. But if I was to do it again I would get the umi adjustable ta with the tunnel mount bar and driveshaft loop. Is ground clearence an issue for you at all?

[LVZ2881]

Any pics of the wheels on the car?? I'm thinking of getting these wheels and would love to see them on a t/a.

I would agree with removing the TQ arm from the transmission. I have the BMR TQ arm relocation mount to take the load off the tail-housing. I've got the 315/30/18 BFG drags. What are the tire specs for the Toyo's and how much do they cost ?
