slotted rotors opinon
Hey guys looking for some slotted rotors for my 01 is300 but dont know were to look and what brand is the best. What do you guys recommend... thnx for your help

Why slotted? Although they may have some performance benefits, they will go through brake pads quite a bit quicker, and the performance benefits will likely not be noticeable... one thing that will happen is that the rotors won't be able to handle as much heat and will overheat quicker than a good set of OEM style rotors...
if you want better performing brakes without replacing calipers, simply get a better set of pads and replace the brake fluid...

I have fig engineering BBK kit. It uses over-sized front supra rotors, modified bracket, and oem rears. I do some spirited driving thru some hilly areas and I feel that my initial grab when I apply my brakes is increased. I could attribute that to the increased size of the rotors and not that the rotors are slotted.

Buy slotted rotors that are vented in the center, they will cool better than OEM rotors and improve performance. A good brand is DBA or Endless.
Buy some good quality pads to go with those rotors, I'd recommend Endless

Unless you go to a larger braking system that is designed for slotted or drilled rotors, they actually hurt performance...

Have any of you had oem sized slotted rotors on your is300? I notice better gripping and I'm very happy with them. I bought some stoptechs. You're telling him how they get hot and etc yet you don't even know what he will be using them for or brand??? For daily driving moosepower you will be just fine with slotted, you'll get a better bite than oem, if going for looks they look good, go through pads a tad faster but you won't really notice unless you get a super soft brake pad. I recommend power slots by stoptech which give improved cooling. That's if you're doing daily driving and oem size...

I do know how hot they get - they cannot take as much heat as a stock rotor, period... daily driving, sure, they might not as bad of heat issues, but, they still do... so, no benefits, only negatives... unless, again, the system was designed for them... probably won't hurt anything, but, won't help so much either...
get better pads - that is the main difference...

there is no difference in braking power... the slots do not dig in to the pad, else you would be replacing brake pads every other day...

Directional Vane Design
Most Power Slot® rotors match the original factory cooling vane design. In the most popular sports car and light truck applications, Power Slot® has improved the design by using directional (left- and right-handed) vanes to improve cooling. This represents a distinct upgrade from the original equipment rotors, which usually feature a straight vane or pillar vane design. The directional vane is a more efficient air pump. The resulting increase in airflow translates into greater resistance to brake fade and faster recovery from temperature spikes generated by aggressive braking maneuvers.
Power Slots
Power Slot® rotors feature a signature "short slot" design. The slot improves brake system performance by wiping away the debris of used friction material that otherwise accumulates between the rotor and pad. This keeps fresh pad material exposed to the rotor surface and helps prevent pad glazing. The edges sweeping the pad slightly increase the effective coefficient of friction, or “bite,” amplifying brake system response to pedal input. By providing an escape path for water, slotted rotors can also improve initial brake response under wet conditions.

agree to disagree, on some of it. Pads do make a huge difference I will agree there. For the rest, no. This is off there site, so it's not just my opinion but there's a well. Or perhaps stoptech is just full of $*%^ and their word is not credible?....

As far as the slots doing what they say, sure, a little... but not enough to make any measurable difference - in fact, to get the best like this, the slots would have to completely cover the entire surface of the pad... all of those things they say could easily be argued, and they make it a point not to sell it too much, words like "slightly increase" and "can also" are their words that they use to make it a point that they are not using false advertising...

"The edges sweeping the pad slightly increase the effective coefficient of friction"
"By providing an escape path for water, slotted rotors can also improve initial brake response under wet conditions"
If given the choice, I would pick Stoptechs normal brake rotor (Centric) over their slotted rotor, though slotted is not nearly as much of a performance hit as the cross drilled rotors... I should also add that their "improved directional vane" system is only available in a few rotors, and all of the others directly copy the OEM vane setup:
"Most Power Slot® rotors match the original factory cooling vane design."

that's says can under wet conditions.... emphasizing on the rain, not the general use..
also says slightly increases friction, not saying it as a precaution but because that's exactly what it does. Slightly increases friction giving you a better bite. It doesn't say may increase friction or that it could or DRASTICALLY. What it means is, it's been tested and it improves friction and bite but not on a huge scale.
and i'm pretty sure is300 vane goes against and not with the rotor. I know the isf for example has it's vane go against... I don't have my stock rotors so I can't check.
This has probably gone way over moose's head btw. hahaha.
Anywho, we could argue this all day! I still agree with you on the pads b/c you're 100% right. After my discussion on this thread I think the best thing moose can do now is just sell his car. lol
