can anyone tell what are the GT-R rotor specs front and rears?

maybe it sounds stupid but on other forums they are converting from ceramics to metal discs. why? because of maintenance price of the ceramics and limited use time on track.
so, been looking on the GT-R forums and found metal brake discs at a reasonable price.
keep in ind that there was a guy here(or on the other forum) that converted his fronts using RS6 calipers with 380mm discs. been talking with him but he couldnt tell from what car he orderded them.

so, the only one with 114.3x5 that could have 380x34mm were the 2009-2011(US) GT-R, but no metal ones.
probably they have a close fitment to the 370Z.


here is the link with them on metal for just 220$ a pair:
2009-2010 Nissan GT-R Std. Performance Brake Rotors (Front) :: 88Rotors
2009-2010 Nissan GT-R Std. Performance Brake Rotors (Rear) :: 88Rotors

I should have went with these from the start, but maybe in the future if I dont like the 355 ones I'll go with these

lets see the specs on them.

the conversion it seems its not that easy to be done, but my buddy is one of the best welder here
bad picture, but this is it.

we have concluded that the best thing to do in order to center these calipers on the rotors was to weld the caliper and add aluminium, then re-drill them to actual caliper to fit the same mounting points on the car. As you could see from the previous pictures the mounting points on the car are about 5-6 mm wider than the ones on the caliper.

If someone wants to fit these calipers, then go for bigger rotors, the 380 ones - it would be much easier to be fitted with just a bracket.
Also, I've seen that the Mercedes ones have a different mounting points, just like the BBK kits have and that makes it much more easier than using these.
now, I'll go further but it looks like it not a home garage project anymore, but I'll have it finished by next week the fronts.

now its time to machine and drill the calipers.
also, we have changed the bolts dimensions and we went with a bigger one 14x1.25 mm

So, the fronts are done!

Next week we will start on building the rears.

Good stuff! Glad you actually went through with it.

Awesome, your buddy does great work.

[stealthTT]

thanks a lot!!

yes, my buddy is great!!
he's got a huge car related experience mainly welding/metal related, and when I say huge, I mean it.
he's the only one I know that have worked/build WRC cars, like I said on metals.

100% you all see some of his TIG skills on my car this year.
