A lazy man's way to determine brake rotor size?

[werD]

Time is here to do the brakes on my wife's '06 T4R.

I have the pads from Toyota and new pins, but I am wondering if there is a definitive way to tell if she has the 338mm rotors without pulling the wheel and confirming with a ruler on center.

She has a Sport Edition with the 17" rims so I am apt to think she's got the bigger rotors...

She has the bigger rotors with the sport edition

'Nuff said.

Any apprehensions about using NAPA rotors? Price is right @ $65 each.

Stealership wants $120 each. I'd grab Brembos or something similar before I'd do that I think...

It was easy enough for me to use a tape measure along side the wheel to tell my Limited has the smaller ones. As the_josh pointed out you're Sport comes with the bigger rotors as part of the package.

EDIT: I've got Napa Ultra Premiums on mine, I replaced them about 4-5 months ago. I like them, better than my worn out ones, but not sure how they compare to the OEM when new. Probably 90% go with the OEM's from what I've seen.

Good to know.

Since she's hammering out the freeway miles, I'm prone to thinking the NAPA units will suffice, but I am always cautious on house brands since the quality can vary immensely from the OEM or known manufacturers.

Thanks.
