Dieting. Rim Weight? Which is lightest?

[Shad Laws]

Hello-

Keep in mind too... rim WIDTH is a big factor.

The wider the rim, the heavier it is (duh).

For example, I have 16x9 Porsche 993 rims on my rear. Especially once a 245/45/16 tire is added onto it, it isn't all that light. Of course, it is pretty danged light for its size... but its size is huge. Just a thought...

I'm contemplating getting some autocross-specific rims. I'm leaning toward 13"-14" Diamond racing wheels, though. I want a smaller diameter to effectively "lower" my 2nd gear ratio :-). Diamond wheels are steel, not aluminum, but if you get their lightweight ones (which are so flimsy that real-world road use isn't recommended), their weight is hard to beat with aluminum!

Take care,
