Actually, the stock RB6 axle can be adjusted using the axle spacers. I just moved the thicker inside spacer to the outside and the thinner one to the inside. This does increase the track width a tad.
+1 on serrated nuts. Locknuts will loosen over time. I have never ever had a serrated nut come loose. Ever.
