Ive just fitted a set, superpro part number: SPF2358K
Purchased these from the superpro head office in queensland about a month ago, cost was around $50ish.



some of you might recognise these instantly and would know the the stock rubber mounts they replace are as soft as a mouse-pad.

benifits:
- gearbox doesnt seem to shake and vibrate as much as it did (yes i had the group-n sti gearbox mount already)
- bumps and uneven ground doesnt give any additional noises through the driveline
- gearshift stick stays exactly where it should under power and doesnt move about under brakes or heavy shifting, as a result your much less likely to have a mis-shift.
- driveline thump between gears was definatley reduced during hard acceleration,

cons:
- not a quick install unless your on a hoist
- maybe a 2% increase in harmonics in the cabin.

overall id recommend it, its another bushing that tightens the car up and gave me the desired results. although i would recommend that you at least have the group-n sti gearbox mount fitted at the same time or in the first place.

hey tuna, sorry for the thread dredge, it came up when i searched on google!, how are these bushings going in your car 3 years down the track? where do you get the sti group n gearbox mount from too?

great improvement, they really stopped a lot of the slop from the gearbox floating around under the car, so a lot less thumping, plus the gearstick stayed relatively steady, afterwards i seemed to not misengage or miss the gates as often as i used to (on the RA gearsets etc). the group-n mount can probably be found at mrt, rallispec.com, gruppe-s.com etc, good investment in my opinion.
