Bushing Durometer Master List
As promised in another thread, I'm compiling a master list of the durometer rating of both OEM, Group N and aftermarket Subaru bushings. I'll add to the list as different bushings are available to me to measure.
The measuring tool is a Rex Gauge 1500 Durometer that measures in the standard Shore A scale. Gauge: http://www.rexgauge.com/model/item/32 Scale info: http://www.matweb.com/reference/shore-hardness.aspx Technical notes on "durometer" and measuring it can be found here: http://www.rexgauge.com/content/tech_notes OEM 07 STI transverse link, 83 (this is the rear bushing on the front lower control arm, "ALK") 07 STI lateral links, 75 - the rear inner link bushing is 70 07 STI engine mounts, 55 07 STI rear differential mount, 65 (voids present) Group N Transverse links, 75 (voids present) Lateral links, 80 Engine mounts, 88 Tranny mount (6 spd), 88 Trailing link, rear, 80 Aftermarket Whiteline Plus front lower control arm bushing, 85 Kartboy "Race" outrigger bushings, 85 GT Spec ALK, 70 (This info comes from Calvin at GT Spec. I have not actually measured this one but there is anecdotal evidence to think that the actual rating is higher.) Whiteline "standard" ALK, 85 Whiteline "comfort" ALK, 75 (as listed by WL, I haven't actually measured) Whiteline "race" ALK, 95 (as lisyed by WL, I haven't actually measured) * Anyone wanting to contribute a bushing please PM me.
