can anyone inform me if i can fit 280mm rotors and calipers using the same adapter bracket as 250mm caliper? Or is there a differenceother than obvious size between the 250 and 280 caliper? Cheers

im currently putting together the 250mm conversion but ive been told its the same adapter bracket for both so you'll be fine.

makes sense really. on the s13 only the breaks are different not the struts so the mount will be the same

yes 100%

Depends who made your brackets, it they were designed for the 280mm setup you will probably have to grind away a bit of metal on the inside radius if you want to run the 250mm calipers.

Could i get some help?What are the 250/280mm rotors off? Need to up grade my brakes..

They are from japanese import s13 silvia & 180sx

Ive got a pair of the 280mm s13 calipers and discs that I will sell
if anyone needs them.

also got a pair of the 250mm discs which are slotted if anyone is interested in those
they have been run with qfm a1rm pads and will need machining to run any other pad

pm me

think 250mm s13 ca18
280mm s13 sr20det

The brackets if the kev rowley type work with both types of discs and callipers. I ran the same pair on both we went to the 250mm to have more options from our wheel selection.

Hey again,Running 13x7 wheels which would be better for me 250mm or 280mm?

250mm
