C43 Front Drilled or Slotted Rotors Please Help
Hi I have a 1998 c43 Amg I wanted to get better rotors for the front. People say that drilled rotors are bad becuase they trap heat. Slotted ones are better. Theres a website I wanted to order them from the brand is Sp preformance has anyone ever heard of that company. Heres the link http://www.performance-parts-accesso...1/default.aspx

Assuming that the build quality is up to spec (oem or equivalent), drilled rotors are fine. They're not so much as "bad," but they certainly have no benefit either; in other words, purely for looks.
There is a claim that drilled rotors weakens the structural integrity of the rotor itself and may eventually cause cracking issues, but there is only a chance that will happen, and only if they have been repeatedly driven hard, such as at track events or road racing with constant hard braking.
Slotted rotors are technically better than drilled performance wise, but none of this really matters if you're just doing daily driving.

Also:
In my opinion, I prefer slotted, as I track my car. However, I realized my OEM front rotors were wearing down quicker than I anticipated, so I was forced to buy drilled OEMs from the 2006 C230K Sport model since I couldn't afford slotted at the time.
If you want slotted and try to buy from R1 Concepts, Brake Performance, or Brake Labs, the front pair runs about $500 for the pair (if you choose the C43 as your car). HOWEVER, I discovered (after buying the drilled) that I could buy a pair of slotted for the 2006 C230K Sport for half the price!
In case you didn't know, the 2006 C230K Sport is the closest-matching non-AMG car in terms of rotor specs (330mm diameter compared to ours 334mm). So regardless of what path you go (drilled or slotted), buy the rotors for the 2006 C230K Sport.

Just google it yourself and you'll find a plethora of information regarding to how drilled rotors no longer have any benefit in today's age.

I wonder why some top level manufacturers offer them as standard equipment. Must also have a reason.

hmmm funny how top brake builders still sell drilled, like brembo etc, i am not saying they are the cure all, but i would rather have a set of done right drilled rotors then poorly done slotted,,,,,,

Drilled is ample sufficient for street and occasional track (looks nice also). Slotted are recommended over drilled for extensive track use.

Ladies, ladies. We could bicker back and forth all day in regards to what is best. Here it is straight from the horse's mouth; of course we know this already...we just love to debate.

+1 for the video. OEM rotors for the C43 are real and totally directional. You must not mix up left and right, and as such has sufficient stopping and cooling power for most situations
