BBK time! Opine here!

Just bought the JKU, so obviously working on a bit of a budget. Would love to hear WF's thoughts on Big Brake Kits. Pros/Cons, real-world experience, etc...

Background: The wife (whose primary vehicle this is), is used to her previous car's braking ability/style. While I understand that a BBK is not going to make the huge JKU stop on a dime, I drove it around today and gotta say, not impressed with the brakes either.

Target: Better grab on the brakes, both initial and over distance. Stopping power! Would like to not have lots of noise/dust.

Budget: Let's try and keep this under a thousand. XstremeStop looks nice, but $1300 is too much at the moment.

Constraints: 17" wheels on right now, so looks like 13" discs are going to be the limiting factor. Thankfully, this also eliminates the over-the-top stuff like a custom Wilwood setup.

It looks like this means we're generally boiling down to the following 3 choices for BBK's:
SSBC - $940 - 3-piston Alu caliper, ))Stock pads and rotors???((
Mopar - $795 - 2-Piston Cast caliper, big brake booster and master cylinder included, if installed by dealership it carries warranty...
Teraflex - $740 - 2-piston Cast caliper, 13.3" vented rotors, pads are specific as well.

I'm leaning towards the SSBC kit, which is top of the budget range but still do-able. Mainly because 3-piston Alu is just a smarter design and better materials than any cast iron caliper could hope for.

Thoughts?

Major advantage to the Mopar, as you said if installed by dealer, carries warranty, plus all off the shelf Mopar parts. Other posts apparently traced the replacement discs to the Ram 1500.

Yep I saw those, and I'm betting the stealership will want list + percentage for parts and ridiculous labor hours for install. Big part of the reason I'm leaning towards the SSBC kit, not to mention 3-piston Alu calipers. I guess I'm trying to see if anyone has a comparison they can speak to...

Thanks
Erik

The Mopar BBK was found for approx $630 - $640. (Shop install costs if you're not taking it on yourself would be $200 - $350 varying on shop. It's a standard install).

Your SSBC kit (not that familiar, correct me if I'm wrong), is just a 3 piston caliper that uses the same stock rotor and doesn't have a new Master Cylinder, Brake Booster, or brake lines that's in the high $800 range? (And assumably less install cost as there isn't much to install).

There's some proven/tested information out on the forums inclusive of cost on various products. Some of these heavily outfitted rigs (40s, armor, etc) have the Mopar BBK, Dyatrac, Teraflex etc...

If you go the SSBC route, keep us posted on your results. I'm sure the group would love to know.

Good Luck!

I have the Teraflex big rotor kit, 2nd Jeep I've run it on. no issues.
Keep in mind the Jeep is bias towards the rear brakes so IMO a big rotor kit on the front and back plus some good pads is the best way to go for under 1k.

I also recommend the solid rotors, I went with the slotted and they can get dust/mud and squeak.

You can paint them before install if you're into that sort of thing

Thanks this is helpful.

When I think I've got a good handle on this, I'll present my findings to the wife so she can tell me how to proceed

For me if it uses either the stock rotors or the stock calipers it's not worth doing.

4 piston calipers + larger rotors is what I would do, depending on the offset of the wheels 12.88in rotors fit behind 17in wheels. I would contact willwood and see if they can throw something together.

My last car I put AP Racing rotors/calipers on the car, stopping power was awesome above 40mph.

When it's the daily-driven RS6 we're talking about, I agree wholeheartedly. Just for S&G, I checked Wilwood's pricing... ~$1700 per axle. Yikes.

I did TF from and back when I lifted and went 37s. Its a very noticeable difference over stock and I think its something everyone should do when going to 37s. Not only is the stopping distance shorter, put there is no fade and initial bite is a lot better. I think I was about $1050 for the parts from Krawl Off Road and i went with the slotted rotors which added some extra bucks. So there is my $.02.

ProGrip Brake System for Jeep Wrangler JK

Worth a look, and addresses all 4 calipers.

Good stuff isn't cheap.... Probably drops 5-10 lbs of unsparing weigh per side up front with those brakes!

Usually going with just better pads can improve stopping distance quite a bit. Willwoods plus different rear pads is what I would do

The pro grip kit looks like a descent kit... They state 30% improvement however don't provide stopping distance stockmvs their setup. I would bet just better pads on a stock system would gain 10-20%
