Houser A-arms-300ex

LOL. I know I am probably getting annoying with these a-arm/shock questions but I gotta get some answers. Sorry Guys!
But I just bought some Houser +2+1 a-arms for my 300. I didnt think houser made a-arms for a 300ex but I guess they do. Or would the 400ex a-arms be the same. But anyway will I need longer brake lines? I hope not. Thanks

If you have +2+1, yes! if you have just +2 i think you can use the stockers. But the steel braided brake lines make the brakes feel SOOO much better!!!
