hmm depends on what vr4 your talking about but since you said 4 pot I guess your talking about a 3kgt and not a Galant. No they won't be bolt on, you'll need to do some fabricating and you'll have to use 17 inch rims also.

now galant vr4 brakes will work so will base model 3kgt brakes too which is what I have on m car.
