There was a thread where someone installed the Perf SSK on a 1M a few weeks ago. It worked. You might try searching for it.
N54 135i = 80 mm's shifter throws
N55 & 1M = 70 mm's shifter throws
N54 Perf SSK = 55 mm's shifter throws
Can't find the link of the Perf SSK on a 1M. Can someone post it?
Thanks in advance
