Due to the simple fact that the toe link does not have bushings (one dimensional rotation) but instead uses Heim or pillow ball joints (multi-dimensional rotation). You cannot replace these components with anything but an OEM replacement toe link, or the M2 Performance or Pettit aftermarket toe links (which use spherical rod ends in place of the pillow ball joints) or the suspension will bind.

One word of caution concerning the use of spherical rod ends in a street vehicle. The pillow ball joints (rear lower control arms, for example) on the RX-7 are protected from grit and debris by rubber dust seals. A spherical rod end has no such protection, and eventually will "ingest" dust and dirt and cause excessive wear and eventual failure. This is one good reason why a spherical rod end suspension is not desirable for street use, because the rod ends will require periodic replacement.

That said, the M2 Performance toe links are an exceptionally good replacement for the toe links, which do have some play, even when new. I have M2 Performance toe links myself, as well as their trailing arms, but the trailing arms were chosen only for additional wheel clearance, not because they provide any performance improvement over the function of the stock trailing arm with the upgraded bushing.

 

So then within how many miles would you suggest they be replaced given normal track/road use?

I'm sure going offroading with your FD may require a sooner replacement :p

 

Yes I'll take some pics...It's like 40 degrees in my garage right now..so give me a few moments

anyways I would wager that they is room for 10.5 out back also...with m2 components..

 

 

 

THIS is the angle in which you should have taken the pic


Oh, it's 40 degrees here, too

 

Yeah maybe I'll try again...if it's worth it...not many comments after the pic anyways....hopefully still some interest on the subject.

Oh the 40 degrees....one difference...you in NJ should be used to it...
