rear brakes not required for 180
just to let you guys know....
when you fit the R180 diff, drive shafts, bearing housings and bearings, you can use the R160 ( the std ones)backing plates, hand brake ***, brake *** off the R160 set uo, the backing plates dictate what brakes you have to run.
The bearings have a larger OD and the bearing housings are machined to take the larger bearing, the bearing housing casting is the same, just machined out for the bigger R180 bearings, which BTW are the same bearing as fitted to the front wheels.
Also the oil cooler on the JDM 6mt uses the auto radiator for the tranns cooler. It has pipes up the left side rail, you can use a small trans oil cooler instead too.

"You can use all the std wrx drive shafts and bearings on the front, and the rear if you fit an R160 3.9 crown wheel and pinion to retain the std rear diff."
I would most likely go with the 180 in the rear and swap the hubs and axels, but I just wantd to make sure if I got a JDM trans with the front LSD that I could get by with the std. WRX front bits.
Thanks for the answer

Back from the dead!
Has anyone cracked open a 6mt? Mines is the v7 non-dccd. I haven't blown reverse, but it no longer engages properly. I'm most likely doing it myself and would appreciate any guidance or advice.

just to give my piece...
stick with 5mt, upgrade to RA-spec gears. who needs a sixth gear?
sure don't in the qt mile.

Jon, all I know is that the early 90's turbo legacy propshaft will work with the R160. The R180 diff is longer, so the only thing I can think of is the Japanese non-dccd propshaft.

Jon, no. The only driveshaft that you'll be able to use is the early 90's turbo Legacy driveshaft.
