Hendrix diff bushings and one-piece driveshaft

If you use some decent length zip ties, you can pull the e-brake cable at the curve coming out of the tunnel towards the subframe. This will help take any slack out of the cable and help keep them in the plastic retainers on the gas tank. Hope that makes sense. If I had my car here I would take a few pics for ya.

Quick update...the driveshaft is rubbing the tank shield. It clears sitting still but there must still be enough movement under load. I really don't want to run without that shield protecting the fuel tank so I'm thinking about tossing out the offset differential bushings and just going with a set of BMR to regain some clearance. Any thoughts on that option?

That will gain you some clearance.

The offset diff bushings were to correct the axle angles in reference to the differential due to lowering the car. I lowered my car 1" and dont use offset bushings, but run the risk of eventually damaging my axles especially on launch when the axle angle gets more pronounced. I think you'll be fine to remove the offsets and go with a standard of your choice. My opinion so take it for what it is.

At my power level I figure the axles are next in line to fail anyway. All in all it seems like the offset differential bushings created more problems than they solved.

Power is definately gonna shorten the life of any part, especially a stressed one. Sorry I didn't see if you were lowered. I think those bushings were intended for 1-1/2" and lower. I guess it really depends how much you beat on your car Larry. Then again, I don't think many of us here sit around and blow kisses at our rides.

Another thing you have going for you is the driveshaft is aluminum and wont get damaged rubbing the heat shield temporarily like a CF would. You have room to experiment. They do make adhesive back heat shielding that's supposed to be pretty good. That'll save you a little room.

Ah did you not see what a few miles and parking brake cables did to mine from gulfcoast driveshaft video?
But I pulled all my heat shields and did the adhesive backed heat shielding on my tank.

BMR bushings should be here today and may even get installed this weekend.

Even temporarily for a few miles it was damaged? crazy. How many miles were you driving on that? I was thinking that you'd be able to hear it and fix pretty much right away. CF wouldnt let you rub on it at all before tearing into the carbon.

Wasn’t more than a mile or so and it left a light groove. He was able to polish it out though.

Wow! I wouldnt expect that. Thanks for letting me know. Cant imagine the damage it couldve caused the Cf. Probably unrepairable.

BMR bushings installed. We'll see how it goes but my initial impression is that they are much stiffer material than the offset bushings and will hopefully keep the driveshaft from hitting under load. No real difference in NVH and, if anything, the additional driveshaft angle reduced vibration.
