I believe the diameter of the rear rotors on my '97 LS400 are 12.07"
I found a very good price on some replacements that say they are 12.09" in diameter.
Is a difference in size as small as .02" going to have any significant affect on the car?

 

Are they listed for that model and year of LS400?

 

Yeah they are

 

Don't worry about it then, '93-99 should all be the same, so its probably a small manufacturing difference.

 

Great, thanks a bunch!
