New wheels - How to Choose - 540/6

[mrgrant]

I have started researching new wheels for my 540/6. There is so much to choose from. I think I am leaning more toward performance than looks. It seems the performance wheels weigh in about 18 - 22 lbs and wheels with great looks 28 - 32 lbs.

I currently have factory 17' stagged wheels with Dunlop SP Sport E 235x45x17 all around. I have tried to find the 18' parallel spoke M5 factory wheels on eBay but they are rare and tend to have more curb rash than I care for. Besides the price for used is around 2k. I have looked into reproductions and have found a few that are priced around $700 that weigh in at 25 lbs and have the correct offset for front and rear. If I go for a compromise of both looks and performance the reproductions seem okay.

How much of a perfomance difference is there in wheels based on weight? I aslo have seen 2 and 3 part wheels that claim greater strength. These wheels also have 2 and 3 times the price and tend to weigh in 28 - 32 lbs. I am confused on how to select wheels for my needs.

Any suggestions weight, strength and price and how it relates to perfomance?

My second choice is a black wheel.

I have noticed a performance difference both times I've changed wheels. The first time I went from stock 528 wheels to reproduction M5 wheels, a fairly big weight swing up. The handling of the car as well as acceleration deteriorated. With my M3, I just last week put on wheels that are 20 lbs as opposed to stock 24 pounds, and handling has improved a good deal; haven't timed acceleration yet.

IMO, the effect on handling is usually minimal regardless of weight unless your talking about a HUGE weight difference.

Acceleration and braking change a great deal, however. Pay the extra money for the lighter rim. It's worth it.
