Re: HOW To: ADD 2012 jeep SRT8 Brembos to your 2011+ Grand Cherokee!

I've just been to the local showroom and measured up the clearance required for the Brembos on the SRT8. Need at least 70mm from face of rotor to clear front Brembos. Unfortunately the stock 20" rims on the Overland only give 50mm clearance so looks like would need the SRT8 rims etc to make it work (these give 80mm clearance).

I've also made that same measurement...... but are you aware the OEM SRT rotor hats are not as deep as the OEM HD brake rotor hats found on the Limiteds, Overlands, and Summits. This allows for extra clearance and the only true way to tell if the OEM 20" wheels will clear the SRT Brembo setup is to try and mount a 20" OEM wheel on a Brembo equipped WK2.

No one has as of yet, tried to check if they SRT rotor/caliper setup will clear the OEM 20" wheels. I'm tired of asking someone/anyone to try!!

Check out the pics in post # 13 and my comment in post #16 of this thread to better understand what I'm saying!

SUCCESS! 2012 Jeep SRT8 6 piston Brembos on a 2011+ Durango WD!!!!!!!

Re: HOW To: ADD 2012 jeep SRT8 Brembos to your 2011+ Grand Cherokee!

Mine is due for a service shortly and will ask if this test can be made as they have an SRT in the showroom and the guy I'm dealing is quite helpful.

Not hopeful though as looks like the SRT8 wheel has more offset than the 20" OEM wheel to clear the caliper.

The centre of the rotor would need to be thicker than the standard ones to give additional clearance to clear the SRT8 rotors - much like is achieved using a wheel spacer.

Re: HOW To: ADD 2012 jeep SRT8 Brembos to your 2011+ Grand Cherokee!

According to the info on Milous's websight all WK2 wheels have a +56.4mm offset.

Jeep Grand Cherokee WK2 - 2011 Grand Cherokee Wheels and tires

Not sure if thats true with the SRT8 wheels?? I've seen 20"X8" Replicas listed at +32mm offset and 20"X10" listed at +50mm offset.

Let us know what you find out! Thanks

Re: HOW To: ADD 2012 jeep SRT8 Brembos to your 2011+ Grand Cherokee!

As a sidenote - if you have the OEM SRT Wheels like I do and you do the Brembo Conversion - the recommended OEM rotors are JUNK! I live in MI and after having them on for about a month they started squealing. Figured it was rust/water, but it got so bad I just had all the pads replaced after only 5 months (figuring it was a bad set of pads - stoptech) and just replaced with some ThermoQuiets and sure as hell the pads were fine and it's still squealing.

The ONLY other thing it can be is those JUNK OEM rotors that were put on the SRTs. I'm doing some research now as I'm embarrassed having my setup that I dropped over 5K on (Brembos/Rotors/OEM SRT Wheels & tires) squeal at every stoplight, etc.

Don't get me wrong they really make the WK2 but still...

Anyways, if anyone knows of any compatible slotted/driller rotors that would eliminate this problem I'm all ears. (Or perhaps someone can confirm that they had the same problems - Scottina??? ) We were two of only a few guys on here who did this work...please let me know.

Thanks

Andrew

Nope....my wife has put 10000 miles on hers with not a peep.

I have the brembo sport rotors on my 13 Srt....but they are north of $800 for the set plus shipping. I also added the hawk hps sport pads on front and stoptechs on the rear.

It's not only offset that is critical to wheels clearing big brakes - its spoke shape/position. I know from recent experience on my race car. Can have 2 wheels with identical offsets and one will clear calipers by a mile whereas the other will require a 20mm spacer! Notice the SRT8 wheels have spokes that curve outwards whereas standard 20" ones are pretty flat with the outer face of the rim.

Yes, pad material can affect squeal as well as the fitting of backing plates/shims on the pads and attention to using lubrication on contact/moving surfaces. Run Brembos on my wife's 350Z and on another competition car with race pads and no squeal whatsoever. As mentioned above by Scottina86, brake bedding in can have a big impact as if this isn't done the pads will develop a hard glaze which will reduce performance, increase rotor wear and squeal like hell! Might need to go out and give the brakes a hard workout to clear the glazing off the pads.

Check out PAGID Racing which gives some info on bedding brakes by Pagid but same should apply to most brakes. The rotors wont be the source of the problem, that's for sure.

This mod would better utilized if you changed the mastercylinder to the mastercylinder that is supposed to be used for the brembos not the stock calipers. The stock MC does not have enough capacity to give all of the gains for the brembos as it doesnt have the resevore for it.

I'm pretty sure the M/C for all level/trims of 2011+ WK2's are the same part #, even for the SRT8 w/Brembos.
