Hey, just need a small favour, I'd like to know what speed you are doing at 4,000rpm in 2nd gear high & low and 4th gear hi/lo, just so I get an indication of what to expect from the d/r box when I fit it.

I'll be getting a 4.44 cw & pinion and a new STI front 1.5 - 2 way LSD & rear 4.44 viscous fitted so it'll be a bit better geared but a rough idea what difference to expect would be helpful. Ta

I'm not after a rock crawler, just something a bit better than the stock WRX 4.1 set up it has now.

I hope you are getting an STI helical front LSD. I am running 4.44 front diff with a 1.5/2 way clutch pack LSD and hate it. It was set up as a 2 way and the car was almost undriveable so i had it changed to 1.5 way and backed off a little and it made some difference but the car drives like a pig around town and parking. I can't wait to find a helical or torsen from an STi to replace it with

I'll get back to you tomorrow.

I've got no idea what it is apart from being a genuine STi item, a mate imported it from Japanparts a couple of years ago and it's been sitting in it's box ever since, I know it's worth about $2,300 or more once freight & customs are paid but that's all I know....I'll take it to Steve at MMS this week so he can tell me what it is & the best way to set it up & tell me if it's helical or clutch but thanks for the warning though it's not usually my daily so not overly worried.

Thanks a lot AP, really appreciated.

Edit, looks like clutch pack, here's the repair kit parts.

Thanks for that, so it looks like low is about a 20% drop in the 3.9 box which is what I have, I guess the 4.44 cw & rear diff change over should help a little with the 26" 205/60/16's to make it reasonable in the sand.
