Im looking to get some info from guys that are are using these types of trailing arms. Let me know what your thoughts are.

Would the Unobtainium bushings in the trailing arm work just like the M2 or pettit trailing arms? I know that M2 and Pettit are solid but I also think the unobtanium bushing would work the same since they are pretty hard.

Let me know what you think...

 

the ubotanium would be the same as the m2 or pettit..

but the m2 gives you a smiggin more room to run wider reartires..like 1/2 in or so..
and the pettit costs less than the m2...

 

depends on what you want....

The trailing arms are more for clearance issues as Bacon stated...the Unobtanium is bushings only..if you have the arms you dont need those specific bushing because they would be replaced with the arms...

 

I just did the M2 arms on Thursday. It felt a little better and rode smoother for a little while and then Friday night it just started riding really rough. Everything is fine with them but I think I might have busted a strut or messed up all the bushings and don't know if it is a result of the arms or not. The "clunking" is worse and every bump is hard.

You might want to check and see if
M2 included the wrong I.D. bushings.
They did me.
Luckily I checked them before install

The unobtainium sets only include
bushings for one end of the arm.
So the other end of your arm would
still be attached to a stock rubber
bushing.
The M2 arms have a bearing on one end
and are attached to the stock rubber
bushing on the other end.

 

Correction: the Unobtainium trailing arm bushing replaces the rubber bushing at the "eye" of the trailing arm, which is the forward mount. The trailing arm bolt passes through a pillow ball bushing in the lower control arm which is not replaceable with a standard bushing because of the required range of motion.

The pillow ball bushings (rear lower control arm and the knuckle bushing in the rear upper control arm) are not rubber, they only have rubber dust covers. The joint itself is metal-on-metal like a spherical rod end, with a spherical "ball" retained in a socket. The difference is that a true rod end "bushing" doesn't have dust covers and isn't greased.

The M2 and Pettit trailing arms have spherical rod ends at the forward mount of the trailing arms. Both have bushing inserts which offset the pivot point inboard to allow slightly more wheel clearance.

 

ID bushings? The only thing I got was the arms with the "eye" joint on the end and the short rods that connect to the eye that you put the bolt through. So basically they only replaced one bushing, is that right?

 

Sorry to go off topic a bit but how hard is it to instal the trailing arm. I am thinking of doing it myself and I don't have a hoist. Thanks

 

My drivers side was easy but the passenger side bolts felt like they were welded on.

Take the dust covers off, 5 - 10mm bolts, then you have a 14mm bolt to take out near the rear of the wheel and then a 17mm bolt to break loose at the other end for each arm. Took me maybe an hour but 20 minutes of that was trying to break a bolt loose.

No need to remove wheels or anything, just jack up the rear of the car.
