Rear-end and diff question...
I just purchased a 2003 S2000 with 72XXX miles.
1) How would you know if you have a rear aftermarket diff? The car seems to be real aggressive when I start off and also seems to want to spin/spool the rear tires in most turns. I am new to the car so it might all be driver error. It just feels like it has more bite then my friends S2K.
2) The rear seems to have a vibration under low speed hard acceleration. I was told that it is most likely the axles due to the car previously being lowered and not having axle spacers. It is now all back to stock. If the CV's are worn, would this cause low speed vibration under hard acceleration?
Thanks..

1) If you have stock gears and running stock size tires at the rear, then you should see 30mph at 4000rpm in 2nd gear.
2) Axle spacers do not prevent damage to axles on the s2k. They may have some benefit on FWD cars though...but not the s2k. The vibration is from pitting in the CV buckets. Spacers can however get rid of the vibration by moving the place where the spider gear rests inside the CV bucket...basically moving it away from the pitting. Since you may not know how long the car was lowered before, adding spacers may or may not work. Your best bet will be to swap the buckets from right to left.
