I know this sounds like a stupid question...

I have an SC300... think my rear rotors are wasted.
I have a new pair of SC400 rear rotors.
A quick bit of research shows that the SC400 rear rotors are 12" vs. 11.4" on the SC300.

Anyone ever tried to mount rear SC400 rotors on an SC300?
Does the SC400 have different rear calipers (I know the fronts are different, but the rears too?) or is there a different mounting bracket or something to handle the (slightly) larger rotors?

I DID use the search, but didn't see any relevant threads.

Thanks

I asked a similar question and I have found mixed answers, some say yes there is no problem and others say they wont fit. The SC400 and NA supra use the bigger rotors, but the NA supra has the same calipers as the SC300 and the SC400 has a different caliper. So I'm still looking for this answer as well, I pretty much stole a set of Brand New supra NA rotors and they will be here on Thursday so if we cant find a definite answer by then I will give em a shot and post up the results

 

i once tried installing sc400 rear caliper on my sc300 b/c i thought it was the same BUT NOOOOO it wasn't...the sc400 rotor is bigger than the sc300 so no it won't work unless you install a sc400 rotor and caliper then it might work..

 

Just an update......there is no way in hell the SC4 rotors will fit on the SC300 with SC300 calipers, I just tried for ****s and giggles and the rotor wont clear the caliper.

you need the sc300tt rear 290mm rotor and sc300tt rear caliper.

there is a sc400 upgrade to sc300tt rear brakes thread on a forum cant seem to find it
