well i have a quick question for ya all, i work at a CNC shop, a really good one, we have the best machines the best programers etc. so it wont be a shisty job but i was wondering if it was worth it or possible to dimple and slot my rotors, is there going to be any noticable difference from stock braking? thanks

 

slots would work better, the only reason they are there is to help the gasses that form in between the pad and rotor to escape. I wouldn't really recommend doing this to your stock rotors, they are pretty weak....just save some $$ for real slotted rotors.

 

i agree, your going to reduce the integrity of the rotor

if ur going to do it , id only slot them, i wouldnt bother dimplingb

 

modern pads dont have that gas build up therefore making the slots/holes useless. i ran both slotted/slotted drilled/drilled on street and tracked a few times on slotted/drilled, i cracked a drilled rotor once. currently i have plain brembo blank rotors. there was no difference between any of the rotors and brake fade on the street or track.

 

ok cool thanks

 

The answer is no. Your drilled rotors will crack.

 

The only difference you will see is that your rotors will crack if you drill them and your pads will wear out about 20% quicker.

 

We sell dimpled/slotted rotors. There is no reduction to the integrity of the rotor by dimpling. There is a reduction in material but it is so little that it does not create a weak spot. If it is drilled to deeply then you would have an issue.
I would not do anything to the stock rotors as they are soft. We sell all 4 slotted for less than the front 2 front the factory. I'm not putting the price here, this isn't an ad just and FYI.

 

concentrate more on finding a good pad that wont fade after a hard run

 

Just remember that the stock rotors are soft. A pad that fades less puts more heat into the rotor and will wear it out quicker.
Our cars brake better than a Lambo Murcielago, stock. Decide why you need to stop better and then make a decision.
