Hey gang,


looking to add some spark to the wheel area and I will be adding 19" to my ride
MVR magnums to be exact...before I do that I would like to add a kick to the roters...
visually...so??
A) do I get them painted??? is it possible and easy??? and cost affective??
or
B) get new color roaters??? and what kind or how much $$$


thanks ,

-idoizm... [:D]

lets see. painting the calipers would look sweet. and getting some slotted or drilled rotors would add some performance with look. tiny rotors in big wheels can look goofy, but you shouldn't have to worry.

There are several types of rotors , other than the traditional "solid" metal ones that are stock

There are slotted rotors, which from a performance standpoint, will "clean" the pads everytime they bite down... creaating a nice clean surface every time you press the pedal ( a really nice featire IMHO)

There are Cross Drilled rotors... check out Porche ... they look like someone took a drill to the rotor and popped a few dozen holes in the sides.... this is to allow "gasses" to escape while braking...

THen there is Cross drilled and slotted which is a mix of the two

THe Cross Drilled look cool

Drawbacks:
Since we have gone away from asbestos based pads, the gas build up is not as much of an issue, so getting the cross drilled is really more "fashion" than performance (generally speaking, unless running a specific race pad that creates gobs of gasses, etc)

Cannot re-surface these rotors when you replace your pads

The Cross Drilled ones actually do not store as much heat as the solid rotors (the biggest killer of rotors is excessive heat - warping) and can tend to warp faster than solid ones

If looking to add more bling, go with a Cross Drilled rotor... If looking for more STOP, get a good set of PADS

yeha, good pads and good tires are what you need. BUT the slots in slotted routers are also for venting gas. the drilled holes are for cooling. slotted and drilled, well, look at porsche, those are drilled, not both. no car comes with both stock. even the enzo, drilled. slotted and drilled seems to be cosmetic, but what do i know. in theory everything sounds great, but its what happens on the road that counts. don't leave chince pads on new rotors, don't get ass-quality tires either. my two cents

Actually, not quite true


TAKEN FROM A RETAILERS WEB SITE FOR THIS PRODUCT!!!!!


Slotted Rotors:
For true high-performance applications, a brake rotor should have as much mass as possible – since the mass of the rotor determines a rotor’s ability to store heat. Powerslot brake rotors maintain more mass than a drilled rotor and feature 6 slots machined into each rotor surface to “clean” the face of the brake pad and prevent glazing under extreme conditions. Powerslot rotors are also coated with a bright silver coating to resist corrosion and maintain an attractive finish over time.


Cross Drilled:
Stillen’s performance brake rotors are designed to improve pedal feel and stand up to the rigors of aggressive driving. Stillen rotors are made with top-grade materials (for less warpage), computer engineered drill patterns (for gas venting), chamfered holes (to prevent fractures), and a gold cadmium coating (to prevent rust on the rotor edges.) This results in better pad contact and improved pedal feel – especially in wet conditions where water reacts with the hot rotor, creating a layer of steam between the rotor and pad surface. Gases and steam escape through the cross-drilled holes to reduce the "mushy" pedal created by gas buildup.


BTW - neither of the above were for a BMW specific...

SO

Slotted = Prevent Glazing
Cross Drilled = Escaping Gases
