S15 diff in r200 housing

[s13pimp]

Woops! Sorry about that!

Okay, I installed my s15 helical diff. It seemed to require no additional shimming. However, something seems to be a bit weird with it. My alignment is pretty bad in my car (to the point where you have to countersteer in order to drive in a straight line) but with the open diff, it would drive straight when getting on it (still have to countersteer, but same amount as when you're driving normally). After I installed my helical s15 diff, the car seems to pull to the right when I get on it (so much so that I can straighten out the wheel when in boost and it drives straight). Then when I come off boost and coast in gear, it goes back to pulling to the left due to the alignment being off and you have to quickly countersteer again. I did figure 8's in a parking lot when i first installed it to sort of break it in (coasting around the turns and accelerating on the straight) and it seemed to loose a lot more speed through the turn when turning left. When turning right (entering at 10 mp) I would leave the turn around 8 mph. When turning to the left (entering at the same speed) I would leave the turn going around 5 or 4 mph and you could feel the car slowing down a lot. There are no odd sounds coming from the housing and it feels very smooth. Any idea? Is it just my alignment and I'm over-reacting? Maybe i didn't notice my alignment being off as much with the open diff but it's much more apparent with the s15. *EDIT* It seems to only do this in a straight line. In that case, I feel like it is most likely my alignment since in a straight line, the diff is almost locked (right?) and with both wheels spinning at close to the same speed, I will notice differences in toe and such much more? http://forums.nicoclub.com/zeropost?cmd=tshow&id=408526
