because the final drive ratio is different. the actual gears are the same, however its a final drive of 3.7 rather than 3.545. This makes it such that you require the rear diff, because the "front differential" is inside the tranny.

i see, thanks for the info.

danny, are you gonna rally your svx 6mt? Otherwise it has a 50/50 split that is traction enough. Trust me, Jesse's 6mt didn't skip a beat with a 165 shot of n02!!!!

I'm not quite sure why you guys rave about the JDM tranny as regards to drivability - my family has two JDM's and they both understeer like ba$tards without even pushin' em too hard. In fact I just about pulled myself off the road the other day as mine couldn't claw it's way through the corner. Certainly doesn't feel like a rear biased AWD!
My tranny is in pretty good nick too as far as I'm aware, and camber etc is all per standards.

I am more racing cars on the highway (there still no real police presence to watch roads...).

The major cars i beated so far are the 2001 - 2002 BMW 330ci and the 97 impreza turbo (at the 100mph run).

and i am still running on my auto tranny, my six speed is still in my garage, just waiting to resolve the turbo matter in this forum...

I don't have this problem, understeering and stuff... you should check your wheels balance. if your front wheels are regulated to their maximum outer distance, you will have this problem. you should squeeze them to the inside as much as you can. and if you have aftermarket wheels, just tell the guy to replace your front ones to make them smaller hence have a better grip than the rear ones. For example if you are running on 8" aftermarket wheels, just replace the front by 7.5" or even less, you will have a better grip. and you can even go to the extreme, by installing new tyres in the front wheels and used (midlife) on the back wheels...

First you really don't want to get different sized wheels because what you're talkinga bout with different sized outer diameters of tires is what F's with the transfer clutchpack.

I'd suggest playing around in a parking lot. I've found in my US version, that with hard throttle application, my car slides completely neutrally. (i do have extra stereo weight in the back) but with light throttle, and taking a moderate turn, the front end can just slide one me. I think mbtolozcko's rear sway bar would be a good solution to neutral handling all the time

How much of a handling difference would swapping a Euro spec tranny for a US spec tranny really make?

I'm going to have to replace / repair my tranny in the next year or so max, and was considering going with a Euro spec auto and have it worked over by Level10 in Jersey.

A six speed would be nice, but I've gotten used to the auto (I'm gettin' old too.) And would like peoples opinions on what the difference would be? Any Euro or Aussie drivers input would be tremendously appreciated.

Yes, you don't want to screw with different sizes Silverspear - the rear bar in my case is a much better option. In any case, putting smaller tires on the front would make it understeer even worse I would have thought.
