SuperPro seems to be only avail through catalogue dealers, i cant find a price. I assume $150 based on JDM applications
They also seem to have the better reviews and design bushings to be squeal free by incorporating grooves.
EDIT:
Price is available from certain Superpro retailers in USA, I got a quote.
It is more expensive than Whiteline/Nolathane, less expansive than Powerflex Black (or even Powerflex Yellow- Yellow vs Black is about $20 per side delta). The price perhaps is equal to OEM m3 bushings or AKG offerings which hover around $250-300/set from various sorces.
For reference Powerflex Black Subframe Bushings:
(PFR5-420BLK) REAR SUBFRAME FRONT MOUNTING BUSH
(PFR5-422BLK) REAR SUBFRAME REAR MOUNTING BUSH
For reference Powerflex Yellow Subframe Bushings:
(PFR5-420) REAR SUBFRAME FRONT MOUNTING BUSH
(PFR5-422) REAR SUBFRAME REAR MOUNTING BUSH
I am deciding between OEM vs being guinea-pig
EDIT 2:
Got email replies from Mfgs.
Whiteline/Nolathane durometer rating is 75A
SuperPro is 80A
