i'm currently doing the 067 e46 rack swap onto a manual rack e30, and it seems a bit of a mish mash as to how people manual the rack, i THINK my options are:
1) just drain all the fluid, and dust seal (but not sir seal) the pipe unions - supposedly can make the rack jerky and possibly stiffer.
2) pipe up the rack to itself and leave it full of fluid - not sure if this would be any less stiff than above as you'd still have the fluid to move?
3) pipe up the rack to a small fluid res - any better than 2?
4) gut the rack, remove the pas fluid seal from inside, then grease it up and put bolts in all the unions - technically now a proper manual rack, so no problems?
my mind seems to say 4) is the best option, but very few people seem to do it - why? any opinions on the above or how you have done yours greatly appreciated!
e46 rack swap - opinions on manual converting rack please
