Poly suspension bushings Superpro vs PSB

[Monkeywrench]

2008 Mazdaspeed 3, 165k-ish, currently all stock suspension.

Will be installing less than a year old suspension from my first Speed 3 that I returned to stock proir to selling, but want to change out all the suspension bushings as a "preventative upgrade/all done in one shabang/one after that fact alignment" effort.

I'd be happy enough with factory rubber, but don't want to mess with, or chance aftermarket rubber replacements, or even look at OEM costs.

So poly it is.

Parts going on.
Bilstein B8
H&R Sport springs
Godspeed rear camber arms
front strut camber plates. Forget brand. From Poland. They did what I wanted, allowing to adjust camber to around 1 degree for tire wear.

So for a bushing kit, just looking for stock replacement, not any additional enhancement with specially designed bushings for altering caster/or camber (Superpro). Stock-ish ride (lower durometer) bushings would be ideal.

Super pro though generally well regarded to my undertsanding, is a bit pricy at $699 for the full kit.

PSB full kit (only offered with wrong option for sway bar bushings, no biggy as I have those replacements already) far less at $175.40

Neither actually list the durameter, which i know would really only come into play for apple to apple comparision if the two production thicknesses/masses were the same between the two venders anyway.
PSB states "the highest grade of polyurethane and the durometer of the bushing is designed to fit the application", which would make me believe maybe a softer bushing/closer to stock ride versus more performance based pitch of Superpro.

Anyone have expeirience with either, or any other I may not have considered offering a full kit?

Anyone have expeirience with both?

Any other input, advise or thoughts I may not be considering?

I have the power flex bushings I got from @Matt@DamondMotorsports only have a couple hundred miles on them but pretty happy so far

I had forgotten those but re-found them after my post. I wasn't seeing a complete kit, and it looked like piecing one together is around the same price range as the Super pro. I'm sure they're both good, but dang!

I haven't tried the cheap set, but I've been meaning to pick one up to see how it compares. There's a few bushings in that cheap kit I wouldn't personally install on my own vehicle due to the design. Mainly the front LCA rear bushing, and the trailing arm bushings. My guess is most of these are going to be significantly stiffer than OE and other options. I would guess 90a-ish for most of them.

We primarily run and sell Powerflex bushings. They do come at a premium, but they have a lifetime warranty (which is insane for a wear component), and their quality is better than other bushings we've seen. The do offer a softer "street" version of many of their bushings, and it's probably the softest option out there. I run the street ones on my DD that I rallyX, and ran them on my wife's Volvo S40 (same bushings and suspension as the MS3) before that car was wrecked. I run the race ones and ALK on my Focus ST that I track (same bushings and suspension as the MS3).

If you or anyone plans to buy a few sets, we do offer a 5% discount on 3 or more sets with the code "PFset" and a 10% discount on 5 or more sets with the code "PFbuild"

Feel free to hit me up too if you'd like a recommendation on which ones to get, or if you'd like us to put together a full package.

I have the street bushings for what its worth

Honestly for the amount of labor involved in making the switch I feel like its a buy once cry once scenario. Unless you are seeing tons of great reviews on the cheapest kit I would spend the extra money for a known quality.

Also lifetime warranty? I plan on dying with this car so I definitely will need to test that warranty
