Well obviously a wheel with the exact same specs as the WK2SRT wheels will clear the Brembos. But nobody knows if the Overland wheels have the same specs. All we said was if you don't want the SRT wheels, and you want to retain your Overland wheels then you should consider finding out if the wheels will clear the Brembos before someone spends a lot of money on the BB upgrade. If you don't think there will be any problems, please, buy them and let us know how it goes. Hopefully it's not a waste of money.

Re: WK2 SRT Brembo brake kit on an Overland

Mako, you come across as arrogant and think you know everything. Telling people who you do not know that they do not know what they are talking about, makes you sound like a Knob. You are the one acting like a 5yo thinking you are right.
You have lost any credibility based on the fact you do not know how to discuss a topic, only lecture people and put them down.

Right, since they aren't out yet, how would anybody be able to answer tge question. Using knowledge we do have from the first generation SRT and wheel fitment issues we tried to answer as best we could.

For someone asking a question you seem to have argued as if you already have the answer.

You have a arrogant attitude if I was to judge you by your responses thus far.

As for "calling people out" there really is no need. If you don't agree with a statement then have some respect and say it without a cocky attitude.

There is more than one Jeep forum online. Acting like you have been to the site owner will have you asking questions on JU rather than here, trust me... You don't want that! Lol

All I can say is this, we've tried to give you an answer to a question that has limited information. That's the best anyone can do.

Re: WK2 SRT Brembo brake kit on an Overland

Hi guys, I am a new member here. Hi to all btw!

I just arrived to this great forum searching for ways to improve my breaking. Specially, after a comparison between the WK2 and others SUVs at Consumer Reports.org

I have a WK2 V6 70th. There is no way to improve my braking distance?

Different kind of pads? rotors?

I will leave factory calipers there, but I asume those 20" wheels added some weight and I am just looking to improve my breaking distances since the Consumer Reports.org #s were not so good for the Jeep, specially under wet conditions...ummm, tires?

Braking from 60 mph dry, ft....

142 - Buick Enclave (CXL V6)
139 - WK2
126 - Cadillac SRX (Luxury V6) -
126 - Acura MDX (V6)

Braking from 60 mph wet, ft.....

153 - Buick Enclave (CXL V6)
157 - WK2
134 - Cadillac SRX (Luxury V6)
131 - Acura MDX (V6)

Re: WK2 SRT Brembo brake kit on an Overland

Tyres will improve the stopping distance, performance brakes will improve the braking performance.

Re: WK2 SRT Brembo brake kit on an Overland

Ok, forget about stopping distances.....I just want the Brembos for looks. Can they fit my Overland and would it be that difficult to install or just bolt on parts....of course there is the cost too.

Re: WK2 SRT Brembo brake kit on an Overland

Well considering the SRT8 is not released, I would say NO. Until we can see the stub axels and mounging brackets, it will be difficult to see if they will just bolt on.

Re: WK2 SRT Brembo brake kit on an Overland

straight from dealer repair manual

"The front knuckle (8) for the SRT8 is different from the standard knuckle. Although similar in appearance, the knuckle has been modified to accept the larger tire and wheel assembly. Also, the mounting bosses for the disc brake caliper have been moved to allow for mounting of the Brembo six-piston disc brake caliper (2)."


"The rear knuckle for the SRT8 is different from the standard knuckle. Although similar in appearance and in service, the mounting bosses for the disc brake caliper have been moved downward to allow mounting of the Brembo four-piston brake caliper."


We have confirmation that the knuckles and caliper mounting points are different again from wk2 to SRT.

Re: WK2 SRT Brembo brake kit on an Overland

I, for one, believe 100% that Scottina06 experienced dramatically shorter stopping distances with the SRT8 Brembo setup.

What Frydryce did not take into account is that the SRT8 rotors are 360mm in diameter vs. 328mm for the standard WK. The greater diameter of the rotor pushes the pads farther out towards the leading edge of the wheel. As rotor diameter increases, it becomes easier and easier to slow a spinning wheel due to a simple rule of physics called leverage. The increase in swept area means the pad need less friction for a given deceleration and is able to generate a higher peak deceleration.

Chrysler put huge 380mm rotors on the WK2 SRT8 because it has gotten obese and needed stronger brakes.

The downside to larger diameter rotors is an increase in heat generated by the larger swept area. Hence, SRT went with six pistons to better withstand heat and lessen fade. They should have gone to eight pistons for what they charge for the new model. And yes, Frydryce, I would agree with you that if Chrysler went with eight pistons vs. six, the stopping distance would not have changed. It is rotor diameter that shortens stopping distance, not number of pistons.

Re: WK2 SRT Brembo brake kit on an Overland

^^ Well, for a learner like me, it makes a lot of sense as to why the 8cyl comes with larger brakes and mine, the 6cyl, doesn't even when I have 20" wheels from factory.

Maybe for me upgrading to a factory 8cyl brakes will help reduce stopping distances without too much investment... to the mods wish list!


Where do I get the WK2 repair / service manual? From a popup window?

Re: WK2 SRT Brembo brake kit on an Overland

Wow, interesting thread lol! Bravo!

BEFORE ANYTHING ELSE: READ THIS:
http://www.mgf.ultimatemg.com/group2...ake_myth_1.htm

My thoughts follow:

Scott dont let the trolls get to ya. Someone will always be in here with no post history talking up a storm about something they think they know a lot about haha, maybe it was, Rick G???? Who remembers him lol

Anyway quoting some of what RoseCity said above about large rotors I have a few points to make clear based on things Ive learned over some time with brakes and track days etc. Beyond simply larger surface area and heat dissipation, large calipers will equate to large surface pressure area. The more pistons or the more piston surface area will simply mean more pad surface pressure against the rotor which will equate to more force pulling on the wheel. So it is logical and follows traditional thinking in a sense. More surface area and more force will equal a faster slowing of the wheel but then it ALL COMES BACK TOT HE TIRE. Thats always the final factor and hopefully not the limiting one.

I have to say though there are many other factors beyond this that affect stopping forces and distances. Slotted/C/D rotors are another subject touched on a little in here. But in my mind, surface area is they key concept in all this. The more rotor the better as long as it can dissipate heat effectively so it can retain its chemical compound so that the pads can still bite on the rotors. Thusly why race cars use the Carbon Ceramics and also there are some fancy silicon/carbide pads and other types or fancy pads that deal well with head But thats another debate for another day

Anyway regarding Scotts info and tests: I know you posted all your old info about the stopping distances and ANYONE WITH A BRAIN can tell you going from a stock braking setup to the LARGER BREMBO SETUP WILL DECREASE STOPPING DISTANCES (if and only if) the tires you are running are NOT the limiting factor - Basically just means that the tires have more grip available for a higher input pressure form the calipers on the rotors.

SO BASED ON THIS: If the tires you had on your truck at the time you swapped brakes (had some headroom for stopping pressures - as far as the breaking wheel slip limit goes) THEN THE BIG BRAKE KIT WOULD DECREASE STOPPING DISTANCES. This is assuming IDENTICAL conditions of course as that is big factor as well. So, Id say pending you had decent tires with a solid rubber compound and good surface area and the days you did the test were identical in an identical location then the kit WOULD (AND CLEARLY DID) DECREASE STOPPING DISTANCES.

This goes on to prove that MOST of the time, a big break kit WILL HELP stopping as long as your tires have the ability to stop faster without slipping and activating ABS - thats how you know, slam the breaks does ABS come on? The the wheel was slipping, brand new set of tires mine never comes on, but thats basically how you know

As far as the original topic in here about upgrading I can tell you this: (as mentioned many times in here)
You NEED the SRT spindle so you can MOUNT THE CALIPERS. Without those well, you'll be in a river somewhere
You also NEED a wheel with SRT offset specs because of the huge caliper. I dont know what the argument was about??? Its been proven not to fit (engineer said so)


Beyond the parts needed for the swap, the reasons to do it are obvious. Beyond less stooping distances, Brembos WILL NOT FADE nearly as much as OEM brakes so anyone driving fast/hard on the street or tracking will really notice the differences. These are reasons to get the kit.

I knew Id benefit as my tires were brand new and that most tires out there (thatd Id buy) are well capable of taking advantage of the bigger brakes, I mean the tire manufactures know these kits exists and go figure, so many cars come with OEM big brake kits and have a brand name tire! How about that.
