hi and Merry Christmas!

Anyone experience this kit?

the full rotor kit...

how much is it better than stock?
how close is it to GT500 size front/rear brake upgrades?

thanks all !

 

I liked that kit, and almost ordered it. They had it on sale at one time for $600, which is a great deal.

I ended up piecing my own system together:
Stoptech rotors $214 on ebay
Hawk HPS pads $135 on ebay
Earls Hyperfirm SS Brake Lines $110 from In Motion Performance
Valvoline DOT 4 Synthetic brake fluid, still better than the DOT 3 that comes stock, but a few degrees short of Motul 600s boiling point- 10 bucks
So ended up with around 500 in the whole kit with shipping.

Impressions, 20%-30% better than stock. Even with the extra weight of the bigger wheels and the KB up front, the car stops much better than stock. Quite, no squeal, a little firmer brake feel, and a little better "bite". I'd say the biggest improvement is from the Hawk HPS pads. The Stoptechs are crossdrilled and powder coated, and look a lot better than stock, but I don't think they help much, if any, and weigh exactly the same thing as stock. The lines give just a tad more of a firm brake peddle feel, but for street driving, most people probably won't find them useful unless they've got old brake lines, then might as well get these. But, for 500, I'm pretty pleased with the new performance. If you're looking for a "big brake kit" type of performance, this probably won't do it for you, though it is better than stock.

You could try just the Hawk HPS pads which I've heard some people found for only $85 and get the most bang for the buck.

 

put it this way you will feel a big diffirence in stopping time, enough that it is perfect for daily driving and some small autocross situations

 

Well if your Mustang is a daily driver and you are not doing competetive sports with it, your money could be spent more wisely ... unless you have money just burning a hole in your pocket and they will look cool. If you are into open track, or similar, these would be good value. For the once in a life time panic stop, not sure your stock brakes will let you down, and if you have your senses about you at that same instant your ALB will allow you to steer away or around what ever it is (with minimal risk to loss of control) that you are about to smack into.

The slotted rotor is a better enhancement than the cross drilled. Cross drilling can cause steess risers which can lead to fatigue cracking of the rotor. Rotors specially designed for cross drilling probably fair better.

I notice Hatchman commented on synthetic brake fluid. The major downside of that stuff is its a more compressable fluid than generic brake fluid and it will have a softer feel and pedal travel will be slightly more because of that.

 

thanks dragon! thats the info. i was looking for....that would probaly fit my needs perfectly...

 

thanks Rad! ill definitely keep this info. in mind...slotted for sure based on this info as well..

 

Any information on that? Not that I am doubting you, but more for my own education.

 

i am thinking the SSBH (stainless steel brakes hoses) make up the difference, from what i heard just replacing those gives a firmer feel to the brake pedal

 

Got any more infor to back that up? Not doubting you, I've just never heard that before. The Motul RBF 600 is also synthetic.

It would appear the higher boiling point of the synthetic DOT 4 would far out weigh the minute difference of the compressibility of a practically incompressible fluid. If it boils, the vapor formed will cause a spongy feel thousands times worse than the difference between one brake fluid and another. The silicone base brake fluids are more compressible, but they have an extremelly high boiling point.
