newbie here from the uk and just want to say that this and the substitute parts page have been a total life saver for me here, think there are only about 10 cefs at the most that i know of in the whole of the uk so u can imagine wat its liek to get parts anyway i just tried to put a 180sx front lip ( called a prefaceleft 200sx s13 here ) on the cef bumper today and . I dont know if its me, the cef or the uk version 180 lip that was wrong but im be hard pushed to say its a direct fit or even a close fit
normal way around the lip is a good 4" to wide and if u turn it around so its upside down its still at least 2" to wide and completely different shape, so when i bent the edges of the lip round the cef bumper it flared out like a uras kit and dipped in in the middle
i'll get some pics as its taken me a good 3-4 hours of cutting chopping and sanding to get it to a near half decent fit
