Does anyone know if it will be possible to put the SRT 8 brembo 4 wheel brake kit on the Overland?

If so how would I go about doing this and anyone know ball park costs? My dealer here was as helpful as a corpse answering this.

You will have to.switch spindles/knuckles in the front and adapter plates in the rear....plus all associated parts like brake lines etc. You should also consider will the front wheels from the 2011 go over those massive 6 pot brembos?

Apparently this isn't true, and the front Brembos will in fact bolt right up to all WK2 front spindles!

Now the question is will they clear the OEM Overland 20" wheels as well??

if youre going for a BBK, get a set of 6 piston stoptechs and be done. Will be about $3K+ for any system (until the stockers start showing up in junkyards and on eBay - still $2K or so for the used ones).

look at the pics of the 2012...its the same as with the wk's. Different front spindles and different mounting plates in the rear
 
#12 ·
heres the nonsrt wk2 suspensions...notice the spindles


The SRT wk2 is set up the same way except the spindles and rear plates are unique to the SRT(as confirmed by an SRt enegineer) to adapt to the brembo bolt spacing and larger rotors.

yeah....yr gonna have to be patient. let the aftermarket catch up or do something completely custom. Really all it takes is some custom machined brackets if you dont wanna wait on SRt parts.
 
#16 ·
yep....the SRt is built on the same platform as the wk2. Now Im not saying that the spindles is all you will need...but going by the photos that are out...thats aall it looks like.

Why would the brembos not bolt right up to WK2 spindles? Keep in mind the WK2 Limiteds and Overlands are both running 20" wheels, same as the WK2 SRT8's. I don't see a clearance issue like you had with your WK w/ it's smaller non SRT8 wheels.
Because the shape of the inside of the wheel, and offset will determine if they clear the brakes. Just because they're both 20's doesn't mean they will both work with the Brembos.

Are you saying the shape of the inside of a 20" SRT8 wheel is somehow different than the "shape" of an Overland 20" wheel?? I'm pretty damn sure they're both circular! I realize the offset of the wider SRT8 wheel would be different, but that shouldn't mean, (although it might?) OEM brembos would not work with OEM 20" wheels even w/different offsets!

Does anyone have actual Mopar 2012 WK2 SRT8 parts lists w/ specs to tell for sure?
Yes I am saying that it is possible. Of course both wheels are round....:confused:.... the clearance issue isn't that the brembos will contact the "hoops" of the wheels, it would/could contact the backside of the wheel spokes... So, ya the shape will matter.

OK............. I really shouldn't but............. Please do tell how the "shape" of the inside of one OEM 20" wheel is somehow different the the "shape" of another OEM 20" wheel??

This is going be good!!!!!!!!!!!!!!! :eek:

Do you run 4-sided blocks for wheels on your rig? :slapfight:
I'm Joel.

Here... I guess you need it drawn out for you. The two "OEM" wheels you are talking about are made for two different vehicles.

Here's a pictures showing the contact points that you should be worried about.

The shape of the inside of the spoke matters whether you think it's a joke or not. Just trying to help, so you don't waste your money. but w/e...

Yes thats true but I don't think wheel offset will be the issue, although until anyone has some hard facts on specs for OEM '12 parts it's all just speculation.

I still think that the '12 OEM Brembos should clear the Overland 20" wheels, (backspacing may be an issue), and I can't imagine why they wouldn't bolt right up to regular Overland spindles with both rigs running 20" OEM wheel packages.

its all guessing right now...but 6 pot brembos are pretty large. Joel is moneen. His point that the back of the wheels does have a bearing on fitting the brembos. I have seen wheels spoked with the bqack side hallowed out to save weight, I have seen them machined down etc. AND...the BREMBOS DEFINATELY do NOT bolt up to the non-SRT spindles.....that has already been confirmed by an SRT engineer. The spindles are different again because the wk2's and SRT's calipers have different bolt spacing just like last generations.

The bigger brakes won't net you shorter stopping distances, I've had plenty of discussions about this time and time again over a span of several different cars. Big brake kits are typically only for race applications when you need to stop your vehicle on a track from 100-40-80-25-60-15 and so on... the larger brakes give you a larger surface area of which to dissapate the heat energy and prolong your system until the effects of brake fade start to errode performance.

The "mushy" feeling you have in your JGC are mostly attributed to rubber brake lines and OE brake pads. If you want to have better feeling brakes, the best cost effective way is to swap out for SS lines, upgraded pads, and some better fluid. oh also tires. Tires are in fact the only contact that your vehicle has with the road, crappy tires on a 16 pot 16" brake system won't do crap.

In short, until you feel the effects of brake fade, you don't need to upgrade your calipers/rotors. And even when you do, a simple pad upgrade will normally do the trick. If you're just doing it for aesthetic purposes then all my arguments are moot, and you can carry on.

^^^^so let me get this straight....put the same wheels/tires on two jeeps...but put brembos on one and keep the other stock and they will stop in the same distance? LOL....I had the exact scenario with my jeep. I switched to the 20" rims/performance tires...then I added the brembo conversion and now my jeep stops like 20' shorter than before......

frydryce is correct.
2 stock JGC's with everything the same except one has performance brakes, they will both stop the same distance, however over several stops the performance brakes will start to win out purely due to better heat dissipation.
Tyres will make all the difference, not the brakes. This is one pet peeve I have with people who will upgrade the performance and braking, but buy $100 tyres. Without the good rubber the power and performance brakes will never see their potential.
A stock JGC with slicks will out brake a JGC with performance brakes and stock rubber.
I have also had this argument many times it is all about the laws of physics.

Yes, I read you whole post.

2 stock JGC's with everything the same except one has performance brakes, they will both stop the same distance
This is incorrect. The difference between WK brakes and WKSRT8 brakes are CLEARLY noticeable the first time you touch the brake. To say otherwise makes me think you've never felt the difference. Its HUGE. Like Scott said, it took 20' off of his braking paired with performance tires.

however over several stops the performance brakes will start to win out purely due to better heat dissipation.
Well i'm pretty sure most people use the brakes more than once while driving... With that said, again.. they're better than stock just for their heat dissipation factor if nothing else, although unlikely.

A stock JGC with slicks will out brake a JGC with performance brakes and stock rubber.
Incorrect. If both tire sets stick the same, the performance brakes will bring you to a stop much sooner. But in that case you're comparing tires and brakes, not just brakes.

If you want an even field for testing tire grip, then put stock tires against performance tires with the same brake setup on the same vehicle

This is one pet peeve I have with people who will upgrade the performance and braking, but buy $100 tires.
Nobody was talking about $100 tires, and most of us have quality tires. If someone said, I want to upgrade my brakes but leave everything else stock, then I would agree with you. But lets just assume they're smart enough to know that suspension, tires, wheels all have a hand in braking improvements not just the brakes themselves.

May be you should learn basic physics and do some research.
Well physics tells me that a larger surface area with more pressure distributed across said surface area will perform better. But i'm not a physics professor. :rolleyes:

Enhanced modulation and bite, and decreased fade are exactly what I'm seeking from a potential Brembo upgrade, which I agree should include less elastic lines, semi metallic pads, good bleed, and stickier rubber.
With all of those factored in you will have a great upgrade. better than stock WK breaks with SS lines, good pads, and good tires.

Not to say that those wouldn't be better than a stock set with no upgrades.

Lol ya... Brembos won't increase your braking performance... Right... This thread is officially a joke...
 
#30 ·
Did you even bother reading what was said ?
May be you should learn basic physics and do some research.
If you do not agree then tell us why you think you are correct, rather than calling the comments here a joke.

its no joke....when i switched to the brembo brakes...I did some pretty exact testing to see exactly what i was getting. EVERYTHING on my Jeep was the same for all tests except for the rotors, calipers and the rear pads. I had wagner thermoquiet pads on the fronts of both brembos and stock wk brakes...the only different was I used ceramic pads on the rear of the stock wk and stillen pads on the rear of the brembos. Both events I used the same technique...emergency braking. The stopping distance from 60 mph for the stock wk brakes was 145 ft(best of three) to 152 ft. The best stopping distance on the same road, same spot, same weather etc for the brembo equipped brakes was a best of 125 ft and was never above 130 ft even after 10-12 hard braking events.

This above test was on 2007 and JeepGarage wasnt even around then. My ytest was revealed on another forum that has since lost the info due to a software switch. Most people here know what forum Im speaking of.
