Add a 40" tire to the mix and a stopped tire 100 feet sooner is better!!

I drove the TeraFlex Jeep with these installed and trust me, the claim is not BS. The Jeep DOES stop quicker. The TF Jeep also had 38" tires on it at the time.

 

What's the word on the rear kits!!?? My rear pads are shot and thinking of upgrading while I'm doing the work.

 

the reason the jeep stops alot quicker is because of the different pads their using, not because of the bigger rotor and caliper. Ive studdied alot of braking dynamics, I come from the bimmer track world and mods like these were plentiful in that catigory..

The braking system on your JK more than suffices, even with your 40" tires and a 2.5 ton vehicle. When your doing laps around the track and ur brakes dont bite anymore due to heat buildup, yes then I can understand upgrading to bigger rottors and bigger piston calipers. Slotted rottors and designed to expand gasses and desipate them asap when theres heat buildup between the rotor and the bad from friction due to sustained intense braking, (this means canyon running or track racing), for jeeps this is complete bullshit unless your doing the canyons or something. In fact, they actaually will do the exact obosite if you do alot of offroading, slotted rottors will catch more debris, mud, sand, and rocks in only to get cought up in your pads, which will eventually start cracking and failing, then again thats IF you take ur jeep offraod.. I have alot of respect for Teraflex, but I do have to call BS on this product since I do know a few things about braking systems (which I do admit is one of the few things I know). Every company has to sell a few products here and there that is more towards the subject of form over function to make a bit more $$$, this ones a prime example... cross drilled rotors are all show, I dont even see them around on the track anymore, they are prone to cracking earlier in their life span. you will not see a peny in return for having drilled rotors on ur jeep besides people that dont know any better starring at it.

you will not take the stock rotors to its fade limit with normal driving. or even 1 "ohshit" panic braking. its just not possible. Now with that said, yes complete race setups might be in a different catagory than all out setups, but the concept is the same. Yes, I know the whole "bigger rotors = better heat dispation or heat transfer " if your replacing a rotor and going to buy better pads, is it worth spending the extra $200 for the "AWWW" factor or "bling"? thats one you, dont use the excuse of "I need better brakes" to get there though

If you dont beleive me try it on ur own. buy pads that bite a bit more, put them on with braided lines and do a test run on ur jeep. now do the same thing with ur bigger rotor caliper setup and see what happen. Ive done these on my E30 M3 and I saw a very slight difference in fade on teh track. on the street you wont see any difference. the calipers TF offeres arnt even monoblock, their the same design as the stock ones.

you want to stop quicker? get some good quality pads, grab some stainless braided lines and your GOLDEN... instead spend ur extra money on something more worthwhile, like a winch or something.

you can argue all u want. , call up brembo, stoptech, bear, willwood... They'll all laugh.

 

I think that the way that this brake performs better is by having more contact area between the pad and caliper. I am sure that brake pad composition has a role to play as well, but primarilly if they have more surface area to clamp against then the brakes can stop the Jeep faster.

 

I can lock my brakes with 37s very easily, I only have upgraded lines and pads. "stopping faster" is relative. if both stock and aftermarket brakes lock up a tire whats the point if ABS is going to negate and take control.

 

While you have the calipers off.....DEFINITELY swap in some steel braided brake lines....definitely! Makes a nice difference in pedal feel. I do this to all my racing bikes and it's a significant improvement. Much less expansion of the brake lines and that translates into more hydraulic force at the pistons to pad to rotor.

 

Pad compound has EVERYTHING to do with it. the lager rotor size just increases the heat sink and reduces fade after prolonged hard use like track driving. Even towing a large trailer wont tax the stock system with good pads. Having raced time attack WRXs and Evos for the past 7 years I quickly learned that upgraded pard and stock size rotors will out brake even a stock 911 turbo. Great stopping brake pads usually comes at the expense of squeeking and more dust on the rims when driven arround town in my race cars. However this upgrade would look great behind the SRT-8 20s that Im thinking about getting on my jeep.
