New brake kit from "Precision Brakes"

Can you post a link to see them ?
Would like to see what they look like.

Frode,

As a rule of thumb, the biggest rotor diameter you can fit inside a 15" wheel is about 285 mm, inside a 16" wheel is 310 mm and inside a 17" wheel is 335 mm and inside a 18" wheel is 360 mm. There must be a reasonable clearance between the edge of the rotor and the wheel in order for air to flow through the vented rotor. Also, if the clearance between rotor & wheel is too small, the glue on weights used for balancing the tires will be scraped off by the calipers, I have seen this happen. "Doh!"

So the 325 mm rotors will not fit inside a 15" Campy wheel. They will require a 17" wheel.

When shopping for all new brakes, as opposed to upgrading the oem brakes, keep in mind the brakes are a substantial part of the unsprung weight of the vehicle, you want the rotors to be mounted on aluminum "hats", you also want the calipers to be cast from aluminum. Some may argue, but 4 or 6 piston calipers offer superior braking perfomance. Keeping the unsprung weight as low as possible allows the suspension to follow the surface of the road better, enhancing traction and improving the ride quality as well.

Cross drilled rotors look cool, but they offer no performance benefit. Cross drilling has lost favor in racing, rotors are most often slotted these days, as it weakens the rotor less. So the added expense of cross drilled rotors is not justifiable from a performance perspective, but it's worth about 0.2 seconds per lap in "bench racing".

Price wise, the Precision Brakes kit seems to be about as expensive as a Wilwood brake system. The Wilwood system is choice quality stuff.

Best regards

I looked at Precision's site and they sell Wilwood brakes, probably the same as Pantera East's

You did not say whether you are looking for street brakes or racing brakes.
I bought a street system from Pantera Performance Center. I have been very happy with it. The instructions were very good and it came with all the little parts you might not consider. You will have to make a couple of small brake lines but everything else is there. Brackets that fit, little caps that allow your existing rear brake calipers to function as a parking brake. Master cylinder. Bleed-back preventer valves at the master cylinder. Wilwood calipers. New larger front discs and hats. You use your existing rear discs which saves disassembling the rear suspension. The proper brake pads. Stainless steel lines and all the fittings. Even brake fluid!!
My brakes are VASTLY inproved. They are not too grabby when hot and they are not ineffective when cold. They are just right! Very progressive as you mash the pedal and with a lot more pedal travel than the stock ones.
You need to be careful in matching up your master cylinder. The one that comes with the kit did not match my brake booster. There seem to be several "stock" boosters and master cylinders. I ended up getting a new dual stage brake booster (which I would recommend) and a different master cylinder.
The whole kit, including master cylinder, was around $1700. Upgrading the booster was around $300.
They also have racing brake set-ups if you're going that direction.
I was looking at Precision Brakes at one time as well. I can tell you that I inquired by e-mail and by phone about Pantera brakes and NEVER got a reply.
If you go with the Pantera Performance set-up, Dennis is very helpful on the phone. I can walk you through a few things myself.
Later, Mooso.
