Performance gear boxes vs std boxes

[CP]

Also elsewhere on the site but i thought it might be useful to someone at some stage in here as well:

Standard cluster on the right c/w std.helical cut gears and Quaife 5SCCR(5 speed straight cut close ratio) on left (partially dismantled). The only difference between the 2 are the straight cut gears and the ratio selection in the SCCR

Quaife SC dog engagement cluster. Substantially different with bigger heavy duty SC gears, no synchro packs, stronger selector forks, dog engagement, modified end cover with bearings

Also got different selector shafts. These have the indents for the spring loaded nibs to locate into, closer together thus reducing the overall travel of the gear lever mechanism throughout. They also have more holes drilled in them for the selector securing roll pins

Does dog engagement just mean that you can be rougher with it, or is there more to it than that?
