Should the Race Tech Rotors be turned(cut) before installation? I read that a couple of other guys that have them say the cad coating on the rotor surface wore off.

umm..... never heard about it. don't you just install it and use the pads to eats up the rotor area that the pads are in contact with?

SandRock

Could you re-phrase that

BananaGS

that is called bedding process. you don't need to resurface new rotor. The cad plating will wear off, that is normal.
you will have to go through bedding process for new rotor or new brake, some called "break-in period"

here is how:

look under Powerslot rotor break-in

I have RT(Racing Technology) rotors on my GS. The cad coating do get worn off after 50 miles of driving. Do you expect the coating stay on the surface as new? You can do it by NOT applying brakes when stop

Yeah bro. I had Power Stop & Power Slot & both end up that way. It's perfectly normal dude.

Hey man when the weather gets warmer we should hook up wit
Philly-Cat, nudderGS400, & me for a mini local meet just to check out the rides bro.

Some people say that all rotors should be cut (new or other wise)before you put them on. I think in the cutting process the cad surface would end up on the floor. What I was trying to get across was, is it ok to put these on without cutting.:eek:

I put up a post a while ago about the same thing. Me and Lextacy400 meet at the Franklin Mills Mall sometimes. Its another car meet place up in the northeast that we should all go to and rep Lexus(in the summer). He says he is the only guy wit a Lex up there.

JacobT

No. You don't need to cut them before install. Just remember to genetly break in those new rotors for the first 20 miles.

yeah i never heard about the cutting part too. but i do believe the very first time you instaleld new pads or rotors, it's to drive hard (10 to 20 times hard 60-0 stops) and then let the whole thing cools down

I heard of someone that purchased new rotors that were warped so they cut them before they put them on. I put them on this morning. Everything went ok except a fitting piece missing out of the kit. They broke in fine. Thanks

ah ic. well i believe if a rotor is made good it should be good surfaced to begin with

SandRock

Good point. The rotors look good on my car but I cant say the stopping power has changed. Im going to give it a little more time.

New rotors the same size with the same calipers won't make any difference. You might slightly decrease brake fade after repeated hard braking with drilled and/or slotted rotors. Steel brake lines will improve brake pedal feel but not stopping power.

Stopping power comes from bigger rotors, more powerful calipers, and most of all, stickier/bigger tires.

and by theory, with the same size slotted / drilled it might hurt stopping distance coz' you get less surface area
