Toyota MR2
if you take the standard clio bumper off. cut a square out of each side including the mounts. Cut the same square out the sport bumper, plastic weld them together put abit of fibreglass/flex on the back for extra strength then prep and paint it direct fit sport bumper that can come on and off time and time again.
No of any guides or pictures of this process? also what do you mean by plastic weld?? all new to this kinda stuff! lol. or if you have it done a picture of yours?? cheers
