Seems there are several different size rotors listed as fitting a '99 TA WS6 suspension, actually the WS6 isn't an option so I'm assuming all V8 cars and maybe even V6s had the same size front rotors??
Major difference in thickness, one is 1.024" and the other is 1.272". Diameters of 11.93" and 12.008" which isn't that much difference. Which is correct??

Thanks

 

Took wheel off and mic'd the rotors, they are 1.257 thick so the thicker ones are the ones to use.
