CRZ rotors

[GeoffM]

Do the back rotors look bigger then the front?

[Tippey764]

On the new 2009+ TL i know for fact they are

the fronts are like 12.6 and the reats are like 12.8 or 13

the sweep area is smaller though so they won't preform as well, as well as the fact they aren't vented rotors.

[GeoffM]

Well for RWD cars it makes more sense. But I'm almost positive this isn't RWD.

Nope, they aren't bigger, in fact they are smaller (10.2 vs. 10.3).

Why would it make more sense for RWD?

No.

TL is FWD or AWD, the brakes are the same between both versions though

Surface area > Diameter.

Ok first of all, surface area of a rotor is a function of its diameter so that doesn't make any sense.

Second, larger brakes in the rear makes no sense at all, even for a RWD vehicle. When you brake, weight transfers forward, no matter what. It doesn't matter what drivetrain layout you have or where the engine is located. Weight moves forward under braking.

That said, it does depend on the weight distribution of the vehicle...

But if the center of the rotor is larger diameter then the sweep area will be smaller if the overall diameter stays the same

[SSMAccord]

Yes, typically the rear rotor hat area is larger in set ups that have larger rear rotors. This larger hat area allows a drum brake to be inside of that rotor and function as the parking brake example:1999-2003 Acura TL.

Yes but there isn't much variation of the hat diameter with Hondas.

They are not larger. they may appear larger to you but they are not.

I've done absolutely no research into it. When we were doing my friends 325i the front pads were about the size of our back pads. That made me think the rears must've been bigger. That was my logic.
