Ordered my mugen replica spoiler from typerkits on monday, getting it sprayed in NHB by them at the same time which saves a lot of hassle and moeny, bit annoyed as its going to take about a month to get here but apparently the best replica spoiler out there, cost me just under £550 for the whole spoiler with fixings and all other bits and pieces aswell as being painted and postage and packing, cracking deal so cant wait for it to be delivered now.
Cant give too much advice on the front lip unfortunately as never really looked in to them myself, worth having a look on the typerkits website just incase they have what you're looking for.
Have fun!
