Hi mate
I have.

I started out with the CA18DET (250mm rotor) brakes several years ago and changed to the SR20DET (280mm rotor) brakes around 18 months ago.

I had to clearance the calipers very slightly to run the same brackets.

Both sets of brakes were from S13 Silvias.

has anyone done this 280mm conversion ?

Good question!
I have some calipers off a cefiro, and I've seen some s15 calipers too. Both of them had the bigger pistons. They also have bigger pads too. With an A series, the 250mm brakes are more than sufficent.

hey guys..

are the calipers the same size for the 250mm rotors to to 280mm rotors..

thanks blair..

do i have to drill new holes?

dont spose any of you guys could post some pics up at all? or better yet email them to me?

be careful that the calipers for the 280mm rotors still only have the 37mm pistons. Mnay of the larger single pot nissan brakes use a 47mm piston'd caliper. I've found that the 47mm piston'd calipers foul on the caliper adapter brackets severely. As it was I had to shave a whisker off my s13 calipers to clear the stub axle mounting eye.

yeah they use the same bracket, same with using skyline (r32, r33) brakes

its all the same to fit 280mm rotors then it is to fit the 250mm's

hey just after a bit of help i have just started doing the s13 conversion onto disk strut on my ute... now i have 280mm rotors which i have only now realized.... has any1 else done this conversion using the 280mm rotors?

any help would be awesome coz i have no idea

cheers Jay
