Understatement, Pig.

Adding this to my list,...

 

Rotors are, believe it or not, a NASCAR Rotor off the shelf that have been heat stress relieved. NASCSAR uses many rotors depending on the trackl, some bigger and some smaller depending on how much brake they need for the track they are at. The aluminum hats are custom to fit my Porsche 993. The Calipers are stock 993 and have been machined to fit over the bigger rotors and spaced out 1/2 inch to accomidate the larger rotor.
the orange duct is a high temp duct that pumps air through the center of the rotor. What you can't see is the custom aluminum block off plates that force all the air through the center of the rotor at 450 CFM using a High dollar air pump. Works very well. nice to steal some technology from other racing venues.
The coilovers are Motons with custom springs and tenders. They are double adjustable and work quite well. Suspension is all mono ball bearing. This car is a go cart... 2400 pound car.

So if Power Slot's Rotor's are $135.00 ea and good ceramic pads are $76.00, you would spend about $350.00 on a complete front brake set.

The question is:

Will larger rotors/ dual piston calipers for $200 more be worth 200 bucks in performance?

I'm sure the answer to this will depend mainly on tire size, but I'd like to find some stopping distance numbers when compared to stock; upgraded pads/ slotted rotors; and larger slotted rotors with dual piston calipers

(I'm leaning toward TF's set up but don't know if I can make it till March)

 

Do you run 17 inch wheels? If you do, then the TF kit would make sense. I am running 15's so it would cost me a lot more to do the TF kit. I will probably go with better rotors and pads. I think summit brand ceramic pads are in the 30-40 range and are made by hawk if I remember right.

 

I stand corrected with the larger rotors stopping you quicker and that it is more limited to the tire and not losing traction.


That being said I've done more reading on the subject and one point was with a heavy vehicle (the 4-door JK is pretty heavy) you can end up with brake fade during just one stop! Not so much the panic stop, but going down a long steep grade. Sure, you should be using your gearing to help you out in this situation, but there are many "what ifs."

What if going down a long steep hill, a car pulls out in front of you? You will experience brake fade per some articles I've read and stopping distance will be increased.

towing? brake fade is increased even in a single stop due to the extra weight and heat that is generated by trying to stop a heavier load.

Same with larger tires, more heat is generated by stopping the greater mass.


A big brake kit would benefit probably about 90% or more of us.


I'm still reading, but the above is a snap-shot of what I've read.

$500 for a good performance upgrade that will help off-road, towing, and other situations versus rotors and pads that are about $350? I'd pony up the extra $150.


I sure like reading everyone's posts, Corrects my incorrect thoughts and makes me go read more.

 

Exactly!! This is the proper apple to apple comparisson rather than comparing these to racing brakes. Its all about Heat management. If you are doing a lot of driving and towing then some added air movement to the brakes would make a large differance as well. At slow speeds there is very little if any air going to the brakes. More mass is what you need there, not that it will stop fade it is just a bigger safety margin.
I even felt the stock brakes withthe stock tires were questionable. I really feel I need something now with all the weight I added from bumpers, winch and all the large rubber.

 

No corrections needed, you are doing pretty good right now. Read a bit about piston area regarding and disc diameter and you will have a good working knowledge base on brakes.

The disc is like a bank, you get so many stops before the bank is at it's thermal limit at which point the pads friction with the disc will degrade. The bigger or thicker the disc, ussually the more mass it will have so therefor the bigger the bank. Also, the better the disc vents, the bigegr the bank. These things influence how many stops you will get before your brakes fade.


The piston area and disc diameter will influence your actual stopping power, not the amount of stops you have. Piston area and disc diameter will dictate how fast you can bring your vehicle from 100-0mph. The disc diameter dictates the amount of mechanical advantage your pads will have and piston area dictates the clamping force your calipers will be able to provide. Hopefully teraflex can tell us what the piston area is of this new caliper and we will be able to calculate EXACTLY how much increase in stopping power we will get. We can get an idea for it's thermal capacity too but since the pads changed thats a variable that can't really be calculated. We can gander up a good idea though....

 

I would agree that the brakes feel at their "max capacity."

I would venture a guess that the tow rating is limited not just by the cooling system of the JK but also the brakes.

Anyways, I'm now hijacking.


If nothing else, it sure will look cool to have large brakes!

 

[QUOTE=boots;1457093]2) Will the Front and Rear kit fit under the 17" AEV Pinter wheels ?QUOTE]

If they don't, I know that AEV has a kit coming out for the JK soon. The TJ kits are starting to ship this week, and many of the parts from that are the same as the JK kits. They are using Dodge Ram / J8 rotors and calipers.

 

QUESTION do slotted / drilled rotors have a chance to get debri"stones-sand-ect" that would damage the pads or rotors
