do not have power steering , I would have to add the pump just for the brakes alone
I guess what I am trying to figure otu is how to get the feel of Porsche or Merc brakes where the car wants to stop very easily
obviously bigger diameter will help along with cross dilling & grooving the rotor , but sinlge piston / 4 piston / 6 piston , or does it matter
I kinda want to do this once not spend the $$ 4-5 times trying stuff to get the feel I want
The problem is the "feel" is the entire package. How much the front dives and the rear jacks up effects the tire loading and availible grip each tires' contact patch has to give.
Good shocks, stiffer front springs, lower center of gravity (lowered) are non brake system related items that will increase overall braking performance.
Are you looking for great stopping performance with low pedal effort? Or superior pedal feedback or all the above.
I crew on a race team with the Willowood street and racecar technical sales reps. I asked them some interesting questions a couple of weeks ago.
What's the advantage of the bigger massive calipers used on the same rotor?
-Pad wear. The larger calipers support larger brake pads which will last longer in extreme and race situation. Also the thicker pad disperses the heat better. The thick bridge will not really stop better, but will help pedal feel. A weak bridge will flex at first, but really after it flexes it still stops.
-The reason for 4 and 6 pistons is to disperse the load over those bigger brake pads. 4 pistons can still get the job done as the caliper is just designed for that. There is some marketing involved with the 6 piston calipers too. Also the bigger pads will offer more surface area to grip, but still the biggest advantage is wear and resistance to fade.
Brake rotors?
-larger diameter give more stopping torque. But the thickness helps the cooling. Directional vanes help air flow. Mass is a big deal.
The
www.arengineering.com 13" setup uses big brembo calipers and thick rotors. But the "feel" I think you are looking for also is going to be tough. That takes some R&D with your particular car. Front to rear bias, leading and laging front to rear, the hydrualic ratios, and power assist amount are just
some of the things designed specifically into a high end Porsche or MB braking system.
Talk to Andy at AR Engineering. He is a Mopar guy through and through and he will help tailor something for you.
BTW cross drilling and grooving are for brake fade after repeated hard stops. Something you would only take advantage of if you were on a road coarse or you do really heavy and hard canyon driving. Gasses can built up under the pad and the holes/slots expell the gases.
