When ordering brakes what mm rotor do I need?

[bassmacka]

I have an SR5 2007 v6 4x4 but when I look up the vin it says its a sport. I wan to order new brakes and rotors through powerstop. Its asking the size? Obviously the bigger the better but will Ihave an fitment issues?

best way to do it is take your wheel off and it should be stamped on the calipers, or you can half a$$ measure. if you get close to 13" order the larger rotors. unless your vehicle came with the factory 18's though I think you order the smaller size of the two options. you have to order same size you have now unless you change out calipers and all the other stuff inside there

There is a casting marking (WG and WH maybe? don't remember off the top of my head) on the caliper that will tell you if they are sport or non-sport brakes. Or if you ever ran 16" stock SR5 wheels over the rotors it's a sure sign that it's the smaller size, the larger rotors will only fit with 17"+ wheels.

I have 17s I gues I will have to remove wheel and check.

If it says Sport Edition on the front doors you should have a 338mm rotor. If it says SR5 on your doors you should have 319mm rotors.

Thanks!
