What a great thread. Thanks for the effort.

Really interesting to see the differences. Thanks for doing this, Woody!

If a base has red calipers it's because he owner painted them or retrofitted S calipers.

6 speed 150#
5 speed 120#
Flywheel and clutch 40#
Tiptronic with tc 245#

These were all full with fluid and a scale that could be + or - a few lbs

Red calipers on my 2002 base

Thanks for your efforts. This is interesting.

Looks like I need to go back and replace some pics I erased. I did notice I never took a pic of the back side of a S carrier compared to a base carrier. The rear S bearing is larger but more importantly is the reinforced control arm link mount. That's a quick way to tell the difference between a rear S carrier and a base carrier

On Tiptronic models, is there a difference in the transmissions and axles between the base and S?
