well i like the YZ flares, and blue ovals... well you have to be very skilled, though for all these flares some skills or deep pockets for bodyshops are a must!
I since im a student, and broke welded on z31 Flares ( 86 and up) they dont add that much 'meat' like 3 " most, but as im running 10 J rims, i did not need more, however they visually add much more! as they start to widen smoother
look at my website..
Anyway it is possible to fit a whole lot of cars flares, as long as you are skilled upto a certian level, you can make anything fit everything
.BTW i like the r32 GTR lights
