Jeep jk drilled and slotted rotors

Stock ones work fine it’s a Jeep not

Drilled and slotted rotors are EXCELLENT at reducing the weight of your wallet.... that's about it.

For your brake upgrade, the go to is black magic brake pads and centric premium rotors. If you have the coin, spring for the vanco big brake kit

It is a Jeep not a Corvette. Slotted rotors are ideal for high powered, corner handling sports cars that never see off road use. Yes, you may see some off road racing vehicles using them but you have to remember those vehicles are torn down after every race and things like rotors and pads are replaced.

Stick with the tried and true...

As previously mentioned, I would not use drilled or slotted rotors on a Jeep.

If you go offroad at all dont do it... the slots and holes just fill with mud clay etc...

I just upgraded to the extremely popular Black Magic Brakes/Centric Rotors combination 2 weeks ago. It was truly worth every penny. One of the most noticeable upgrades I have ever done to a Jeep.

I hope you mean they work fine with OEM sized tires.

stock definitely dont cut it when going to 33's or 35's.

black magic brake pads and centric rotors are the best braking performance upgrade you can get without going to a big brake kit.

Drilled and slotted rotors work well at speed if your current setup is overheating, its not a problem 99.99% of TJ owners experience so the downside of trapping mud or pebbles is not worth the minimal benefit

Stock is ok up to 32.5 to 33 not really adequate beyond that

The original rubi design was for 33 with stock brakes

Drilled/slotted cool better with heavy weight and reduce unsprung weight neither a typical concern on a TJ setup

Lots of components are marginal beyond 33 tires including bit not limited to brakes

agreed, just didnt want the OP to think OEM brakes are good no matter the tire size.

although, from my experience, my 03 rubi on 35's with bmb pads and centric rotors stopped better than the wife's 06 sport did when she was on 31's with OEM brakes

The original Rubicon design was supposed to have 33s, but do we know that the standard brakes were a part of that plan? Many more things would have been different with that version of the TJ Rubicon.

FWiW, stock brakes were barely adequate with 285/75r16's on mine. I doubt a fraction of an inch less tire would have made a big difference. Black Magic brake pads made for a very noticeable improvement.

Perhaps your brakes were not operating normally

Stock has been adequate for years on wife’s 04 rubi with 32.5 and my sport with 33 summer and 31 winter although discs are CJ on the 98

Won’t drive a vehicle with inadequate brakes

No indication anywhere that TJ rubi had different than what came out brakes in pipeline so I’ll skip that magical thinking

Course both mine are manual so never braking and accelerating at same time with one foot on brake while other applies gas like some slush box gals tend to

and i've always felt OEM brakes were inadequate no matter the tire size. its all relative.

The thinking is no less magical than assuming the brakes would have been the same. Jeep never released a factory ~33" tire on a TJ, so we do not know what they would have done differently or not.

Perhaps. Though we do know that there is a fairly wide range in the capability of the stock brakes to handle larger than stock tires. Some can take the added load, some can't. Blaine himself talks about this.

We should all follow this thinking regardless of what others say is adequate.

I've heard that drilled rotors have a tendency to crack under extreme conditions--hard breaking then a splash of water. I have drilled and slotted rotors on my SRT Charger and they work nicely and can bring the car down from 100mph+ to 65 in a hurry and from 60 to 0 so fast it will make you dizzy. I used powerstop rotors and pads for that car and haven't had any problems.

Slots are to help the gasses escape under heavy use. Holes are also to help the gasses escape but also serve to lighten the rotating mass.

If your rig is a trail rig with only a little road time, I wouldn't worry about the brake set-up too much--But, if you drive like I do (about 25K/yr) then you want safe, reliable and interstate travel worthy breaks.

For my jeep I will be using a slotted rotor (not drilled) just because it's more durable.

Funny the Speedo reads dead on with stock gears and 32.5 tires

I like my slotted rotors. My stopping power went from Oh' Shite! to Holy Shite! With that being said, Its a daily driver 99% of the time and offroad not so much. Its all about compromise over dirt v pavement and staying out of the rear end of the car in front of me during the evening commute.

Only fools tailgate as brakes don’t improve your reaction time
I am amazed how many dolts think more cars makes it ok to tailgate

Physics and biology neither make any accommodation for increased number of vehicles on the road even if you live in granola land and most others on road are too damn stupid to realize it

I'm aware that the speedo was incorrect for the factory 245/65r16 tires. This was true at least for 2003, but was corrected in later years. It's an interesting and charming vestige from what might have been. How does that tell us anything about what the brakes may or may not have been during the early development stages? Would the ride height, shocks, drivelines and control arms have also remained the same as stock despite the 33s? What does the speedo calibration suggest about that? Everything else strongly hints at why they didn't follow through with 33s. Too many changes to the production line make work well, which we already know from doing it ourselves. 31s were the compromise. And they were absolutely a compromise on the existing platform.
