2) Is it possible to change the spool pulley in order to use it with the E4FS internal ratio?
My question might have been asked before but it is difficult to read through 209 pages.
Thanks a lot for your time.
1) YES....I think the FS ran the 18T little pulleys (inside front and rear) instead of the 17T for RS and your rear diff, front spool pulley is 1T less then the RS (34T?)...so total 2 little and 2 large pulleys.
2) That I am not sure the SPOOL pulley are able to be DETACHED from the rim.....your best choice is use a DIFF and made a limited slip spool, cheaper and better.
