Thread: custom saw tooth rotor idea

Tweet

ok this may be a bit to much but i was thinking about doing some saw tooth rotors on my new build by taking a solid 13" rotor and cutting teeth around the edge about a half inch deep and somewhat curved like a saw blade . i would make separate right and left sides .

wondering about how i should go about cutting them ? plasma / cnc or band saw by hand .

i think it would look really wild and unique .

or is there a place that sells these ? i doubt it , not many people would want saw tooth rotors ! LOL i just have to be different .

for get about it you will kill yourself....

Why would you want to give up any of the braking area on the rotor for some silly cuts that do nothing other then look "different"?????? I like different too, but not in any way that would adversly effect the stopping power of the car!!!!! Lots of other ways to trick out a car, many of which will actually add performance and safety to it!!!!

I agree. Don't do it. You should never do anything that would compromise your braking system.

yup i get where your coming from but it really would be no different then a drilled and slotted rotor ? it would only be a small part of the outside ring .
look at some of the rotors on motorcycles , yes i know they weight far less then a car but my car is only going to be around 2000 lb .

just an idea and you guys are right , maybe just forget about it ?

but i did see a car at good guys this year that had them done and it was very cool !

Well it is hunting season, you could pop the wheels and do some meat cutting on the side

Wrong! It is different from holes or slots.

The valley between each tooth is a weak area and each tooth would act as a lever arm. When you hit the brakes, the rotor would try to tear itself apart.

cut them with a hack saw. that way they will be so far out of balance you wont be able to go fast enough to need much brake

Kinmonts had a sorta saw tooth to them, but that's a whole different elephant.

If you have access to a cnc, I would go that route, it'll turn out with the best finish, and it won't loose it balance. lightly round the tips, to cut down from them becoming hot spots.
I have seen a lot move cutting on them then that, and they have not had a problem with them, not to say you won't get a crack. Just watch them, if they do, take them off before they get worst.
I like the idea.

here is a pic of the car at good guys .
these are a bit large from what i was thinking .

cOOOOOOOOOLLLLLL lets take the back tires off and cut some ply wood .the way there done should be safe you have a big radius at the root of the tooth

hmmm. maybe it's time to separate show car stuff from what works on a driver???? Gonna spend all that money on good brakes, then give away how many square inches of surface just to be kewl???? (well, it that's kewl, anyway). Best have a good CNC mill and a lot of time if you want to get into that stuff....

Just about any cnc will do it with out any problem. It would take about 15-25 minutes to write the first set of grams, about 5-10 minutes to setup, and go get some coffee or a soda while it cuts it. (Cutting time will very depending on how many different cutters you use & design) switch rotors after it done, 5 minutes to resetup and have a dognut, & repeat for as many as you want.

Been there, Done that many, many, many times.

I don't think it's less surface than if you use sloted & drilled rotors & pucks instead of pads.

How about scalloped rotors . We have been using them on
pavement Late Models and Mods for years . These are on a
Studebaker street rod , ran them for over a year with no
problems .
