UMI Panhard/TA Girdle Clearance?

**M6_WS6** · 01-01-2011, 05:54 AM

All of my UMI parts have arrived except the TA relocate bracket, waiting for that, I`m looking forward to getting started. I`m thinking about getting the TA differential girdle, will I have any clearance issues between the non-adjustable panhard and the girdle? I think my project for next winter will be a new S60, I only have 14K on the car right now, as long as I don`t dump the clutch, I should be ok until then.

Do you mean a girdle for the rear, like this?

If so, I had no problems clearing my UMI non-adjustable panhard bar. The rear pictured is a Moser 12 bolt, which is physically larger than the stock 10 bolt.

Yup, that`s what I`m looking for, thanks. BTW, that one nice clean set-up. I`m planning on mine looking the same when I`m finished. How do you like your Moser? I figured the S60 to be a good "Middle of the Road". I don`t plan on running at the strip, just having fun - but one never knows.

Thanks! As an M6 you may want to go with a 9" and outfit it with 4.10's -- that is the usual recommendation. Our car is an A4 so I went with a 12 bolt and 3.73's as it is the lightest and most efficient of the aftermarket rears (excluding sheetmetal housings). I like it, but it does have a bit of a drone around 1,500-1,800 rpm. I attribute this in part to the tunnel mount torque arm setup.

I thought about the 9" but, I`ve read here that there`s some clearance issues in the wheelwells and the ride height has changed. I don`t want to have to do a heat and beat, and I like the ride height the way it is.

12 bolt will definitely work for you then. The only major modification I had to contend with was the parking brake brackets as I also have the welded relocation brackets for the lower control arms.

In one of my previous lives, I had a 70 Torino Cobra with the 429SCJ, toploader and 9" rear, it really was a torque monster. I drove it hard, the 9" held up great. Based on what I`ve read here, the pecking order is 12 bolt, S60, then 9". I figure the S60 will give me a little more durability than the 12 bolt, just in case. I`d like to go with something around a 3.90 - 4.10 for everyday, especially with gas prices going up again - and expected to go higher. One more question; what`s the best recommended rear end fluid, I`m changing everything this spring, just curious what`s considered to be the besst.

I would probably put the S60 on top of the 9" -- that thing is massive and about 20 pounds heavier than the others from what I recall.

I just use a good 80W-90 gear oil in ours -- I think it was Valvoline. I have a True Trac, so just straight fluid without any additives. I am pretty sure Moser recommended against a synthetic fluid, but not sure why.

The Strange S60 is a Dana 60 really robust unit,if you do not see they drag strip every weekend,with slicks,and high rpm clutch dumps the 12 bolt would be more than enough strength wise.

I went with the S60 because at the time it was cheaper than their 12 bolt. It still might be. The car is mostly a DD but it's nice to know that 60 is underneath there.

I don`t figure on any track time, just want something that`s going to hold up for fun street driving. The rear end will be my next winters project, this year is stiffening the car, air induction and exhaust - oh yea, shifter, skip shift eliminator - for now.

**pajeff02** · 01-04-2011, 03:29 AM

Which posi unit would you go with?

**RyanJM** · 01-04-2011, 03:36 AM

I have the thunder racing girdle on my 10 bolt and had both non adj and adj panhard bars from UMI and they both clear with no problem.

**M6_WS6** · 01-05-2011, 12:00 AM

I`m not sure yet which unit to run, I want something that`s streetable, but I don`t want to hear alot of clunking/binding going around corners. I hear good and bad about the Eaton and Tru Trac. My forecasted torque for the future should be a little over 400 ft lbs. I`ve got a little time yet, I`m just trying to figure a good compatible package for what I want.
Ryan, thanks, it sounds like I`m going to be ok with the girdle.
