M30 Brakes on 240sx

[WOLFANATOR13]

I Was Shopping Around And Found that The Infinity M30 Rotors Are The Same Size As J30 Brake Rotors, Would That also Imply that I Could Use The M30 Calipers As A Big Brake Upgrade for My 240SX? Found One In Local Junkyard, All The 5, J30's Had Their Rear Diffs And Brakes All gone..... I Read That the M30 Rear Should Work And Be LSD Or VLSD, Anybodys .02 Would Be Great!
