Big Brakes on all 4 corners?

I am doing some very long term planning, and have been looking into big brake kits. I haven't found one yet that upgrades all four wheels. Only thing I have found so far was replacing factory sized rotors with drilled/slotted ones.

I know that every vehicle from the factory has a front bias in braking force since that is where most of the braking occurs. Adding more stopping power to just the fronts would only increase this bias. With all the electronic nannys these days, I just wonder what this will do to things like stability control and ABS.

In order to keep the braking bias close to the engineered levels, upgrading the front and rear brakes similarly seems that best way to go. (This is how I have always done it on my road cars).

So does anyone make a complete big brake kit or is the after-market only offering front brake kits?

Only offering fronts right now. The JK has some decent-sized brakes and the majority of the braking happens in the front anyway. It's not like you will be trail braking a Jeep on the onramp. The Teraflex system seems to be one of the nicest ones out there, especially with the master cylinder upgrade.

Almost all big brake kits are for the front only. I have a Roush Mustang and big brakes in the front is very common but the big brakes in the back is very very rare. I know 2 completely different vehicles but still dont see many in the back.

Even the Mustang with the factory Brembo upgrade is the same way.

Down under we get a 13in front disc, but the same size rears. Since I can lock up on dry tarmac and send the ABS into a fit, I dont think any bigger will make much difference.

Is it possible to swap them off a Grand Cherokee SRT8?

A lot of fab work and you would have to run 20" to clear the calipers.

What kind of fab work? Can the brackets and spindles be swapped? Are the rears that different between the two?

Big brake kits look cool but, I think they are better for vehicles that go fast/handle well. For better stopping power, changing out the stock pads for something with more bite might do the trick. Hawk HPS pads do very well but create a lot of dust. Front and rear pads should come in at around 150 bucks. I might do this as well.

I have done many big brake upgrades. All of which were done on vehicles that saw track duty. For street driven vehicles start with the basics first. Upgraded pads and slotted rotors. Do not use drilled rotors on your Jeep unless you like to replace them frequently. Add to that braided lines and a high quality high temp fluid. My bet is that unless you are towing heavy loads or rocking 40"+ tires that will satisfy your braking needs. If you still need more then you need to look at 4-6 piston calipers, large (355mm+) rotors, etc. To run a 355mm rotor requires a minimum of an 18" wheel to clear. So the cost goes up very quickly. A front 4-piston kit with 355mm rotors will run about $3k, new wheels and tires add another large pile of $$. Start small and work up.

The SRT is 4-wheel independent suspension. Safe bet that nothing will transfer. Anything can be made to fit if you throw enough $$ at it.
