i just installed my slotted rotors and the carbon fiber brake pads, and i did the go 20mph slow down to 5mph 5-6 times and when i parked it the front right tire was smoking, the rubber was burning atleast thats what i smelt it soon stopped, i backed the car up and applied the brakes only going about 10mph at most and no smoke,
just wondering what anyone thinks about that

Bad sign, very bad sign <img src="http://www.aaca.org/ubbthreads/image...ins/frown.gif" alt="" /> I suspect that the caliper is not free but binding and only an outside or inside edge of the pad was making contach and heating locally. This procedure should put only a little heat in the rotor certainly not smoke them!
From a previous post of mine: Like all rotors break them in properly.
You can treat them first with Cryogenic Tempering. Pack in large box with dry ice, wrap with a large blanket. Put in deep freezer for 3 or 4 days. Remove and leave in cool basement for 2 more days and allow them still wrapped in blanket to come up to room temperature slowly and you have cryo treated your rotors.
After installation heat treat by accelerating to 20 mph and brake lightly to 3 or 4 mph. Repeat 4 or 5 times and park car for 2 hours to let them cool. They have now been heat cycled.
You rotors will now last a very long time and be very resistant to warping.
Season rotors After say 3 days of normal driving the rotors are seasoned, the brake pads can be bedded.
Time to bed the pads! now that we have your attention and the moderator's!
Bedding is necessary to get the maximum performance from any metallic compound brake pad. During bedding, the pad releases excess gasses from its hardeners and organic bonding agents. Bedding also tempers and cures the friction material so that it will withstand future aggressive use with minimum fade.
Find a location where you can accelerate up to 60 MPH, brake heavily to 5 MPH, and then repeat this cycle several times (usually 5 to 7) until the brakes fade significantly. If done properly, the brakes will smell and may smoke somewhat, that's why bedding is often referred to as "letting the smoke out". Now, drive for 10 minutes or so, at highway speed, utilizing as little braking as possible. Park the car overnight, allowing the brakes to cool to ambient, again, don't set the parking brake, especially if you've put new pads or rotors on the rear.
BTW, if you bought cheap rotors, with poor temper, they will probably warp during pad bedding, so sorry.
PS; You just might want to cryo treat the brake pads also. or get it done commercially at http://www.onecryo.com/onecryo/
