Sorry, I hate dark wheels. I'm old school.

 

I'm with you on this one. To me, dark or black wheels just make your car look like you've got filthy dirty wheels. OK if you want that "track" look, but for a "pleasure" vehicle and a "boulevard cruiser", not my thing, either.
Remember some years ago, "Mingster" started a thread about his BLACK wheels? His wife saw them for the first time and asked why his wheels were so dirty. This turned out to be a LOOOOOOOONG thread with comments ranging from, "Get a new wife" to "Wash them filthy things" to "Why would you spend that kind of money to make your car look ugly?" Quite a mixed opinion. To each their own, I guess.

Anyway Vlad, have fun choosing new tires and wheels. We'll compare notes when I'm out there next July.

 

yeah im different.... im "new school" i like black and dark rims

 

Great thread. My S2000 will probably never see serious track work, it would be fun if we could put together a "lapping day" where we could take our cars to the track and go at a pace that each of us is comfortable with and safely exploit our cars. I would like to take the performance driving school with Reijo as to improve my skills on the street.

 

Sign up for the school! It's going to be a blast.

 

that sounds like something i would like to do

 

just to do the math.....no need to wait.

i think it's called an inertial force vector or something.....

 

...please show us the math!

 

i would, but i don't remember it anymore!!!!!!

university was a LONGGGG time ago for me.

hell, i don't even know if i kept any of my notes or papers.

 

It seems to me that you have to consider two separate (but interrelated) phenomena here:

1. Whether the wheels are heavier or lighter (in toto) will change the mass that you're trying to accelerate forward, and that will change the acceleration proportionally (F = ma).

2. Both the total weight of the wheels and the radial distribution of that weight will change the amount of torque required to spin the wheels up to speed; the more torque needed to spin up the wheels, the less acceleration.

Everything else being equal, lighter wheels improve acceleration, and wheels with their mass concentrated in the center improve acceleration. Thus, smaller-diameter wheels with higher-profile tires (rubber being less dense than aluminum/magnesium/steel) will improve acceleration.

Without details on the masses involved I couldn't calculate what the changes in acceleration would be. My suspicion is that they would be negligible in any case.
