FD suspension bushing replacement, list for full refurb
 
I'd like some confirmation and a second opinion on what I found from forum posts, hopefully making it clear to noobies like me in the future what exactly needs to be replaced when doing an overall bushing job.
Also, some feedback regarding certain components and their performance would be great!

Part #s are from Mazdatrix

From another thread, a knowledgeable forum member mentioned how the full SuperPro poly bushing set is NOT an appropriate replacement for ALL the bushings in the rear. Here's what I've gathered:

Front Suspension
  • SuperPro Polys cover all the bushings
Rear Suspension
  • 6 Pillowballs (J-auto set: I have heard that while these quality products, they're machined in a way that could result in binding? Is this true?)
  • Upper Control Arm (the following can be replaced with SuperPro Polys)
    • 28-8C0A-FD01 (x2 per side)
    • 28-710A-FD01 (x1 per side)
  • Lower Control Arm (due to multi-axis movement these should NOT be replaced with polys)
    • 28-4600-FD01 (x1 per side), $97 Mazda Comp from Mazdatrix
  • Toe Links (Buy new from somebody)
    • Banzai has the cheapest, with TCS Toe Links (Chromoly heim joints) @ $129
    • As far as I can tell, most other vendors use these joints. Is there a difference in other people's toe links?
  • Trailing Arms (buy new from somebody)
    • Again, Banzai has the cheapest trailing arms @129 TCS Trailing arms with Chromoly heim joints
    • Same inquiry, what're the differences between these and some other much more expensive alternatives which also uses heim joints?
  • Differential bushings (SuperPro Polys)
And that's my current tentative shopping list. I've got my coilovers already, just need the bushings. Let me know if I missed somethings or if there are other suspension components I should look to replace while I'm taking everything apart.

Thanks!

If your FD is street car I would consider using new OEM or Mazda Comp bushings for the trailing arms and toe links instead of aftermarket parts with heim joints as I'm under the assumption that OEM and Mazda Comp will last longer and wont transmit as much road noise/vibration as heim joints

The $ :(
 
I would’ve preferred OEM or Mazda Comp for that as well but they’re just so expensive... the TSC toe links and trailing arms are 260 total. I’m pretty sure getting the bushings will end up being close to 400 if not more.

guy I bought my car from put Megan Racing toe links in the back. 10k miles later they were shot.

Get new OEM toe link bushings and use the original links.

Just a heads up, Mazdacomp bushings are getting more difficult to obtain. I heard this rumor from a couple of track junkies last summer, so I ordered a full extra set for my car back in April. Well, the rear Mazdacomp bushing came in fairly fast, the front ones, not so much. The folks at Mazda Motorsports have been playing “Bushing of the Month Club”. Every, month or so I get a small box with a brand new Mazdacomp bushing to add to my collection. I can’t wait until January when my collection should be complete! :)
