needs some advice 325 bits onto 320i

[dazleeds]

as above

firstly can i put the 325 rack straight onto my 320i???
also will i need to change over to all the 325 ps bits or just the rack and use existing 320i bits??

secondly the rear shocks on my 325 are bright orange, whats that mean??
as i keep seeing that diff colours mean theyre different are these ok to go on with the mtec springs??

is theyre any real benefit from doubleing up the anti roll bars ???

im sure theres more so i,ll edit when i think of more cheers lads Daz leeds
