I am going to be doing a full 2006 wrx swap into my 98 RS soon and ill be swapping over a lot of other parts as well into the RS.
However, i have a guy interested in buying the rear knuckles off the WRX. Will i need them or should i keep them if ill be swapping the new rear diff and axel onto the RS?
i know that i can use kartboy brackets to use the 06 brakes on the rear, but would it be a good idea or would i need those rear knuckles?

 

I would use the newer knuckles, It's usually better to have the newest parts in your car, as opposed to selling them. It doesn't make alot of sense to sell the parts you have and can use, to buy more parts to replace the parts you sold.
