Rear Toe/Trailing Arm Links

Hey guys.

I'm curious to get your input on any rear links you've tried.

I installed the Fall Line rear toe links and I can't say there was noticeable change. Plus, there are faint clicking noises when going over bumps. Enough so that I'm thinking of going back to OEM. My shop has checked and everything is tight.

So, have you found any links that have a noticeable impact and are silent? I know Dinan is quite proud of theirs, but not sure if it's worth the cost.

Supposedly the OEM arms and rubber bushings will allow toe change and rear end squirm under hard acceleration. I was already having the rear alignment set, and the fall line links are pretty cheap, so I had the guys pop them in there.

Even if they are helping, the added noise bothers me so they’re coming out. I’ll go back to OEM, unless someone can definitively say a different vendor’s links helped improve rear end stability.

They of course improve stability...it removes rubber from the suspension (which can flex). But the increased NVH is a side-affect...

I have yet to hear real world track performance impact from anyone on these. I noticed a little bit of change, but not worth the added NVH.

Anyone tried Dinan’s or a different brand?

Pretty sure that multiple people here have shown more consistent rear tire wear when using the rear toe arms...

I tried searching around and couldn’t find anything. I’m mostly curious if Dinan’s are silent, or make noise like most all links do.

I don't think any spherical bearing is ever going to be silent...its only a matter of time before it starts to be noisy
