16" rims?

BMW does this with the I cars not so much the XI cars

I can see that happening since the stock setup isn't staggered.

Seems like you're pretty familiar with brakes.

The JDM low-spec comes with ventilated fronts and non-ventilated rears, and the high-spec has ventilated discs for both.

I think the FR-S comes with ventilated fronts and rears. Are ventilated much better? Do they cost a lot more?

I think their reasoning is because the JDM low-spec comes with 16'' wheels instead of 17''. This means you don't need as much stopping power compared to the heavier 17'' wheels. It will also decrease cost.

Vented Vs. Non-Vented Brake Rotors

By Jeremy Cato, eHow Contributor


Vented car brake rotor Your vehicle's braking system involves a fairly complex arrangement of parts. One of the most important of those parts is the brake rotor. This can be either vented or non-vented.

1. Brake Rotor
   
   
   • The rotor is the main stopping mechanism of the disc brake, which is the type of brake used in most modern cars. When the brake pedal is pushed down, the brake pads press against the rotors to stop the vehicle. The amount of stopping force applied to the rotors is proportional to the amount of pressure applied to the brake pedal.
     
     
   Vented Brake Rotors
   
   
   • Vented brake rotors have holes and grooves drilled through them all around the perimeter of the brake. This allows for faster dissipation of heat that builds up when the brake pads act on the rotor. Vented brake rotors are most often used in large or high-speed vehicles. They are also often made out of ceramic or other strong synthetic materials.
     
     
   Non-Vented Brake Rotors
   
   
   • Non-vented brake rotors are most commonly made of solid iron. They are better suited for smaller, slower commuter vehicles (small cars, light trucks, small vans). Non-vented brake rotors also tend to last longer than vented ones.

Ventilated are required for the front. The rotor has multiple jobs, one is to provide a friction surface with the pad, then to remove heat from the pad and caliper and third to remove heat from the brake system. Ventilating rotors help with taking heat out of the pads and calipers and with removing the heat due to their 1) larger mass and 2) ventilation.

Solids are just fine in the rear, but I'm good with ventilated as well. The S2000 uses solid rear rotors and it's just fine on the track.

The rear rotors aren't much different on the low spec (although I haven't seen numbers, it seems logical that the WRX rear 11.3" solid units would be used, both seem to use the 11.6" WRX fronts). Both realistically should fit with 16" wheels, not every 16" probably but many of them.

The larger wheel size will make brakes work harder but either brake setup will have the power to lock up the tires, and if you can lock up the tires than you have more than enough brake force. Whether or not you have large enough heat sinks (rotors) for repeated high speed stops is the question, and the reason for the larger vented brakes all around.

Uhmm that sounds like he's really describing blanks vs cross drilled and/or slotted rotors, not really vented vs non-vented rotors, especially when you throw that pic in with it. And vented rotors are generally iron. Sounds like he's mixing carbon brakes in there too.

I would actually just remove and ignore that entire post, it's so unclear and potentially misinforming that it's not worth having. Oh, and tires stop the car, not the rotors :P (ok unless the wheels and tires have fallen off...)

Yeah I noticed, I think that E-how just tosses pics up as representation

Very good info. Is this an accurate picture showing vented vs. non-vented rotors?

I'm guessing vented is on the left and non-vented is on the right. You can see slots on the right rotor.

Good info guys.
I hope will be able to put BBK into a 16" aftermarket wheels.
Just need to check out the local available tire selection.

A bbk will definitely not fit under 16s. The stock brakes will.

Oops, I meant to say vented rotors on the left.
