FXRs are not easy to install. Do not run over 35 watt ballast with MH1 projectors. If your looking for even brighter go with 4300k or 5000k XB35 bulbs. The more color the less light output. 4300k being the brightest.
Im sure you will be very happy with the 5.0 MH1 setup. Im planning on FXRs soon to replace my MH1s but not because im not happy with my MH1s I just want to try something else.
Yes the MCR shrouds will fit.
