Lets talk about lightweight rotors

Thanks for the input!

Would a person notice any acceleration change due to lowering the unsprung weight although its not on the driven axle?

No.

Removing unsprung weight improves your wheel rate, making it easier to maintain mechanical grip.

When it's on the driven wheels, it lowers rotational mass and reduces driveline losses.

As far as the heat issue... Personally, additional thermal mass doesn't really help much past the first few stops. Having the hub as part of the total thermal system doesn't dramatically increase the (usable) surface area of the system. It's just metal clamped between the wheel and the hub, so yeah, it might put heat into the wheel as well, which can eventually make it out into the air, but i see it as just making it hard to keep your tire pressures stable.

If you have heating issues, install ducting.

But before you worry about all that, like DR said, good fluid good pads and you'll be good to go.

Technically rotors / wheels are the BEST type of weight to lose... unsprung, rotating mass. ...even on a RWD car. (front wheels always turning ya know)

However, you'd have to have quite the butt dyno to be able to tell the difference. I say the DBA rotors are just a good investment in longevity. My OEM rotors warped in 2 days. *sigh
