![]() While Growing up he had been Inspired by friends who regularly attended time attack events or would take their cars out to the local mountain roads. Have we failed by not reaching our first goal at hand? Or, is it that we have stumbled upon a new way to be successful.ĭale Yasay out of Vallejo California started off his build with performance and grip in mind for his 2008 Honda Civic Si. We strive to reach a certain goal to only find ourselves on the opposite end of what we had initially projected. I actually felt my finger tips burn a bit when trying to stop the larger cymbal in as quick a fashion as the smaller one.If there is one thing that we have all encountered in life is the fact that things don’t always go as planned. The larger cymbal was far harder to spin and I never got it to rotate as fast as I could with the smaller one, even after spinning for a good minute or so. I immediately noticed the change in weight, and inertia. After messing with it for a minute, I went to a cymbal twice as large and spun it the same way. I first spun a rather small (maybe 10") cymbal with a single finger, close to the center, then had fun stopping it with my finger-tips placed on the rim. I learned a little bit about weight on a rotational axis when I messed with some cymbals years ago. I like to auto-cross too, which involves rapidly and repeatedly increasing and decreasing wheel speed. When the overall size (wheel and tire) is increased, the braking can suffer, although it may only be minor. As far as I can tell (with wheels I have gotten), larger wheels put a larger load on, not only the drivetrain, but also the brakes. I like light cars, thus my tedious passion for shaving weight here and there. I was a bit hasty in my initial response, but some people aren't looking for a high performance application. The main reason I would consider smaller wheels is for the ride quality improvement of a thicker sidewall (at the expense of handling) LOOK AT WHEEL WEIGHT when getting wheels. I'm not complaining.Īs for picking tire sizes for 17s here are my thoughts on another thread. It's even lighter than the 205/40/17, I guess because the load rating is a lot less. I like the bfgoodrich g-force sports - for some reason the 215/40/17 is really light. This is an important factor that most people overlook, especially considering the tire is mass toward the outside edge. On tire rack if you click on specs you can also see weights of each tire. ![]() Not to mention that a 15 inch wheel has a tire with a much thicker sidewall, and a tire weighs more than a lightweight wheel, so you don't lose much by replacing a couple inches of tire with a couple inches of lightweight forged aluminum. The opposite is true with many forged rims. So the argument that the mass is spread to the outside does not apply. Most forged rims have a forged outer shell, meaning that the concentration of mass is actually more centralized than factory/cast wheels. ![]() I wouldn't buy anything other than forged personally in any size. If you're not getting FORGED rims I say forget about getting 17s. That's huge on a light car with low torque! My car feels a lot faster now. (yes, there are significant weight differences among tires of the same size as well) For example EACH of my 17 inch rear rim/tire weighs a total of 5 lbs less than stock, for less rotating mass of 10 lbs on the drive wheels. It all depends WHICH 17 inch rims you're running. The general statement that 17s slow the car down is just plain wrong. ![]()
