My G50.01 gearbox rebuild is starting and I need to get new synchros. Planning to put steel synchros from 2nd to 5th. I have tried to seach correct part numbers and came to this conclusion:
950.304.311.30 (1st and 2nd as on 964rs)
928.304.211.30 (3rd, 4th and 5th as on 964/993rs+gt3)

Are these correct numbers? Are there motorsports equivalent for these, as many threads people meantioning they used motorsport syncros? Sory but my local Porsche service center is not very familiar with these hence I need your support.

Yep you have the correct numbers. Give me a call if you need these, I have them in stock. Be a bit careful on the 3rd thru 5th synchros, we have seen some that are not quite right in the past, they can cause more trouble then they are worth if they were not made correctly.

Happy to help,
