so the s13 is mine and the s14 is my buddy's. he had originally purchased a set of origin fenders to fix a damaged s14 front end. now they were painted and installed by a paint/body shop but, the shop had nothing but great things to say about the fitment of the fenders. very little modification... now i was so impressed wit the fitment on his car that i decided to purchased a set of s13 fenders for my silvia conversion. straight out the box the fitment was great. i'm not a body guy so bondo, filling, and sanding is something that is new to me "and i'm am going to say the little i had to do i didn't like". but all of the install/paint was done i my garage. i am very happy wit the lines and the end result. i will be buying more Origin products. if you have any question PM me. and i have alot more pic so if there is a certain angle you are lookin for let me know.
