You shouldn't need to change the A-arms, just bolt the DC2 knuckles to your existing ones. As for the lower LCA's, the 6th gen CX/DX/LX front LCA's did not have mounting points for a swaybar. If you have GSR front LCA's, I would try to fit those, since you'd be able to add a swaybar later on. I'm not sure on the fitment between EK and DC front LCA's, so eyeball it, and see if it looks like it'll work. Your stock parking brake cables will not work with rear discs. You can use the DC parking brake cables. I've been running GSR parking brake cables for 3 years with no problems.
