Thread: b15 knuckle swap discussion

on a nx theyd be hot....dont know on a sentra. hard to say. definatley make for an aggressive stance....the s13 wheels were flush with my fenders. cleared fine, but defiantley wider wheelbase.

I sourced B15 rear hubs at pull-a-part today. They have the exact same dimensions as the B13 rear hubs, but also don't use the washers I was concerned about using with the G20 rear hubs. I guess I'll decide what to do when it's time to roll.

I was planning on running those same wheels over Q45 calipers with G20 rear brakes. That should stop fine, particularly on gravel!

The G20 knuckle has a different trailing arm arrangement than the B13. I suppose if you grabbed the trailing arm and the whole knuckle, you could swap it, but I just built rear control arms so I'm not anxious to change that whole set-up again!

I'm confused. Why aren't any of the available big brake kits not an option?

I wanted to try and figure out an easier solution, plus most of the BBK's out there are over $600 and few of them fit under 15" wheels.

I think I have spent less than $200 so far to get B15 knuckles, Maxima calipers, G20 rear brakes and hubs, Maxima MC, Q45 front calipers and B15 rear hubs. I'll spend a little more on longer studs, new wheel bearings and caliper rebuilding, but I won't have anywhere near the cost of a BBK.
