Yes, but only because I will take it to the track from time to time and run very sticky tires. Don't see the need in a street only vehicle.

Re: Drive shaft safety loop

When hanging my exhaust I welded a piece between the two pipes for additional support AND....in case of a u-joint mishap  I'm hoping it will support the driveshaft until I coast to a stop!(last time my rear u-joint $hit-the-bed  it worked pretty good.,..
I've only had ONE U-joint issue in my long & interesting driving career of 60 years  could be much to do about nothing!)

I had one bust loose once in a truck tore some stuff up under the truck too. I had one on y Nova cause of taking it to the track and quit taking it when they said I needed a roll bar too after running one night.

Re: Drive shaft safety loop

On a street car, just something else to get in the way of maintenance.
If a true drive shaft racing event occurred, I doubt a mild steel exhaust pipe would do much to contain it, but it might slow it down a little.


Money you enjoy wasting is NOT wasted money... unless your wife finds out.

Re: Drive shaft safety loop

I did not install a driveshaft safety loop, for the reasons others have posted, but I guess it can't hurt. 
One thing to consider is if the Branda loop will not interfere with the exhaust pipes, and if installed, be sure you can easily remove it if necessary.

The Branda loop is supposed to be  what Shelby used but I dont really know says it uses your seat belt bolts.

Re: Drive shaft safety loop

I plan on installing one.  There are some crazy videos of driveshafts failing on chassis dynos.  Last week someone posted a video of a V8 swapped Chevy Luv that had a violent failure.  If I find it again I will post it.

Re: Drive shaft safety loop

Its never a bad idea.  There are regulations about where its supposed to be for it to be legal for racing.  Second post has the specifics:

https://www.camaros.net/threads/driveshaft-loop-nhra-placement-install-measurements.116035/

Not required unless you are running slicks or faster than 11.49 on street tires.  On a street car I would advise just making sure the u-joints are okay as part of regular maintenance.  I only ever saw one failure on the street and I told my buddy his u-joints were going bad and he just kept ignoring it.  Fortunately it was a low speed failure of the rear joint that damaged nothing other than the driveshaft.

Re: Drive shaft safety loop

I've considered a loop over the years, but I've never had a drive shaft fail on me with any of my cars, so I'm probably with MS on this.

Re: Drive shaft safety loop

IMO those NHRA rules exist for a reason.  Driveshaft/u-joint failure is just another thing that becomes possible with traction, which we don't have on the street.  Now, I've seen plenty of guys lose a shaft at the track over the years.  Usually on a Friday night shutting the track down for an hour.  Just one of many reasons I stopped going to the track on Friday nights.
