Seems like each gear would have different gains on wheel weight reduction so it would depend on what your end goal is but generally less unspring weight seems to be “better” (and more expensive per size)
Rotational Inertia - Equivalent Mass https://www.youtube.com/watch?v=SR3nVx1aaTo -Larry From: [email protected] [mailto:[email protected]] On Behalf Of Holland Phillips Sent: Thursday, January 14, 2016 11:43 AM To: [email protected] Subject: Re: [mk2-16v] Impact of wheel weight on acceleration Back when I was building my '92 GTI 16V, I chose BBS RC 16x7.5 wheels because they were the lightest wheels available at the time. I understood the physics involved, as in the benefits of lower unsprung weight, less rotational weight, etc. All these aspects greatly benefit handling, braking, and acceleration. Not to mention I always loved the look of that style of wheel. They are reminiscent of the BBS 3 piece wheels that were used on the old Porsche RSR race cars from the early seventies, and continued to be used by Porsche and BMW for years on their race cars. ~Holland On Jan 13, 2016 19:53, "Chad Rebuck" <[email protected]<mailto:[email protected]>> wrote: I had never really seen a test like this done. The impact on acceleration is more than I would expect. -- You received this message because you are subscribed to the Google Groups "MK2-16v" group.
