If you want the best bang for your buck buy the pfo reflectors. You would need two 2 footers and they come all pre drilled for vho and your halides. I just did it a little while ago and can`t believe the difference these reflectors make.
Sorry I missed the part where you want 4 vho`s. I think you`d only be able to go with 2 4 foot vho`s.
