no
the 25GT's do lack the GT-T interior, alloys, brakes, suspension, front strut brace, HICAS and rear stabilizer.
from my print out the 25GT has no LSD
it also states an auto GT-T/GT-V has a 'rear screw refuse LSD' and the manuals have a 'rear helical LSD' but I'm sure most of you would know that.
