400ex spindles and hubs..

[300ex_#387]

When you use the 400ex spindles and hubs on a 300, do you have to use 400ex rotors and calipers too?

All you need are the 400 spindles. The 300ex hubs,rotors and calipers mount right up.

Alright thanks, thats what I needed to know. Do you think it is worth getting the spindles? I know its not the greatest set up in the first place, but will the spindles make much of an improvement?

If you are using the 400ex a arms then yes it will help some. When I had the conversion on mine I noticed a larger turning radius with the 400 spindles but they did help with bumpsteer. It still doesn't fully correct the tie rod angle though. As for it being worth doing...I ended up changing to an aftermarket front end built for the 300 because I was never fully happy with the conversion. Not everyone has the same opinion on this setup though. Some like it and some don't.
