when using a rally design quick shif, will this replace my linkage.

also will it replace the bushes as my gear change is shockingly bad, its got to the point were only first and fith are the only easily selectable gears.

i want to no if the r&d kit will make it fell tight again (obviosly not as good as a bm, but even a new standard linkage would be good)

does it replace the rubber parts with metal as in the b&m kit?

will fitting one sort my shonky change?

cheeRS in advance lads
