How much of a difference does offset make?

Question: Would a 0.4 lbs weight savings per wheel be more advantageous than losing 12mm of total track width?

What I am wondering is should I go with 41mm offset (Enkei RPF1s) because they weigh 9.5 lbs rather than the 35mm which weigh 9.9 lbs? Is saving 0.8 lbs per axle a benefit if I am losing whatever small degree of cornering stability with a narrower track?

Or am I just being too damned anal about this whole thing?

Weight difference is in the center and therfore has very little accel/decel mass moment arm. Go with the wider track.

I would compare cost as well. You could add a 6mm spacer and probably be close to the same weight... right?

@StephenB No, what I'm doing is going from Kosei K1s (at 13.3 lbs per wheel and 38 mm offset) to Enkei RPF1s. The decision I'm trying to make is whether to go with 35mm Enkeis at 9.9 lbs or 41mm Enkeis at 9.5 lbs.

Will the slightly wider stance be more beneficial or the narrower track with less weight? That's my dilemma.

Remember, you can always add spacers. If you want the best of both.

And gain the unsprung weight back with the spacer? Come on, really?

Pontiac that baby...wide track!!

Track is one of the components of lateral load transfer. Its far more important then 1.2 lbs of unsprung weight.
