Boomba Racing Rotor Cutting.
Boomba Racing Rotor Cutting.
Eventually rotors do wear
down. Uneven fade can cause premature rotor wear.

understand the importance and we have just picked up a brand new grinder for rotors and flywheels. We have plenty of experience cooking
our rotors on the race course and even more experience in precision grinding and machining.
The rotor before being cut.

Same rotor after grinding.


Side by side, a noticeable difference.
Before I forget to mention, we also offer slotting.
Boomba Racing has decades of grinding/machining experience under its belt
, so you can rest assured that the rotors come out within spec.
*PLEASE NOTE* Boomba Racing will also not machine any rotors below the limit! Even a few thousandths of an inch can cause catastrophic failure. Don't take the chance.*PLEASE NOTE*
We have seen this grinder hold limits to withing 0.0001" which is well within the allowable tolerances of 0.0006". Since we are a well established machine shop
we have plenty of calibrated precision instruments at our disposal to ensure this.
Why spend hundreds on a new set?
All you have to do is hand over your rotor and $50(per rotor) , and we will take care of the rest.

Good stuff, I wished I lived closer. You should throw up so info about flywheels. I've seen way too many issues caused by using a BRAKE lathe to resurface a flywheel. Especially ones resurfaced by places like Autozone or O'Reilly's.
Another good thing.. (I deal with rotors everyday..) the way you are cutting the rotors isn't your normal cheap route that almost EVERY shop and "advance/oriellys" places people are mentioning. They just turn the rotor on the lathe in a circular motion, which can actually hurt brake performance. This is actually the first time I've ever seen rotors machined the way it comes from the "factory". No shop or garage I've ever been to (hundreds) has a way to machine a rotor like that. Looks very nice.
