What MM should I replace my rotors?
Brake rotors are marked with a “minimum thickness” on the casting (usually 2 mm to 3 mm less than the new rotor thickness). Rotors should be replaced before they reach this minimum thickness and should not be “turned” (machine refinished) below this.
Are front rotors and rear rotors the same size?
The fitment front and rear are going to be extremely different. Not only is the diameter and braking surface completely different sizes, the rear disks have a separate machined area inside the hat (the part where it attaches to the hub) which is used for the parking brake. The front one has no such provision.
Can I put bigger rotors on my car?
Just installing larger rotors won’t do anything for performance and you may have clearance issues with the smaller caliper brackets, not to mention out of spec rotor wear that might cause braking issues. If you want to change rotor size, you should be installing calipers to match.
Does the size of the rotor matter?
The simplest brake upgrade, to gain sheer stopping power, is upsizing rotor size. You can exchange brake pads, experimenting with different material compounds for feel and durability, but rotor size has a much more significant influence on absolute brake performance.
Are thicker rotors better?
There’s simply more mass to absorb energy (heat), so thicker rotors tend to stay cooler.
Can I use any rotor with disc brakes?
You can use any rotor you like with any brake, within reason. Some rotors have narrower brake tracks than others, i.e. Shimano, but generally, it’s just a metal disk.
Do bigger rotors stop better?
Having bigger rotors means better heat transfer and better performance stopping.
Are drilled rotors worth it?
If you live in an area that experiences a lot of rain, drilled rotors are a very good choice. They perform well in rainy climates by offering a good “wet bite,” hold up well over the life of the rotors, and deliver more friction and more bite than their slotted counterparts.
Can I use larger rotors?
Upgrading to larger rotors can be detrimental. The extra weight, or mass, in the rotor allows it to absorb more heat. A larger rotor also takes longer to heat up. These factors can bring your vehicle’s braking system temperatures below their optimal range.
Are rotors universal?
Brake rotors and pads are not universal to all cars but can be interchangeable between certain vehicles. The sizing of the pads and rotors, hub bore/pattern, and wheel size are just a few factors that have to be checked before even attempting a swap.
