Thread: 430 Scuderia TRACK WHEELS - TTCompetizioni Spec by HRE Wheels

enojoye them they look like alot of fun! lets see some track pixs!

havent you had these for a while? They look so sick on the car since the brakes fill them up completely!

Saw the wheels at SCX and loved them. Car looked amazing

very nice!

You have a Mini? Iv'e got one to!

Looks great on the scud

awesome!

Is this the benefit of CF Wheels?

Read this on another forum, on a different topic and car but it made me think of this thread.

Less weight would definitely be a good thing, but when you consider that reducing rotational inertia is roughly equivalent to reducing the weight of a non-rotating part by a factor of 6 (rule of thumb - not exact calculation. People used to use a factor of ten but wheel manufacturers are finding that 6 is much closer).

Keep in mind that the work required to rotate (or stop) a spinning wheel is Force net θ = Δ( ½ MOI ω²).

My point (without killing people with math) is that significantly reducing the weight of the wheels (and tires if possible) along with lighter rotors and a carbon fiber drive shaft could result in significant performance gains.

Just using available carbon fiber drum Dymag wheels for our car could result in a 29.15 lb savings that, when multiplied by 6 (best guess), should result in the car feeling and performing like it just lost 175 lbs.

The drive shaft would have less effect because its' diameter is small relative to a wheel, but it would help - as would lighter rotors.

I have seen 6.2 lb all carbon fiber wheels advertised in shows. These could result in a perceived reduction of about 450 lbs. Of course, they never made it into production. Hopefully one day such wheels will.
