Installation of the 5mm riv nuts requires some drilling and fitting of the threaded ends, which can seem like a tedious job, but it allows for easy removal of the overfender.Installation of the 5mm riv nuts requires some drilling and fitting of the threaded ends, With the overfender in position, we marked the mounting holes and drilled them with an M-size drill to correspond with the 5mm riv-nuts. Next, we installed the riv-nuts with a Huck Riv-Nut setter and bolted the overfender in place with some 16mm M5*0.8 stainless button head bolts. These fasteners have a low profile and allow for easy removal/replacement of the rear overfender should things go wrong on track. Fortunately, the mold Spoon uses to make these fenders offers a great finish and no filler is required to get a flush fit to the quarter panel-impressive stuff. We finished off the install with some aluminum stand-offs that maintain a gap at the rear of the fender extension, allowing for the high pressure in the wheelwell to be extracted, which helps improve downforce. The final step was to modify the Downforce CF side sill to work with the Spoon overfender. With some careful marking and cutting, it's possible to get a tight fit of the side sill to the overfender. With everything in place, the final product fits like a charm. The Spoon overfenders give the added clearance necessary to run a 285/30R18 on a 10-inch +35 rim with no rubbing or interference (static camber set to -3). With full compression the 285/30/18 Kumho tires on 18x10 +35 Advan wheels fit flush with no rubbing anywhere.With full compression the 285/30/18 Kumho tires on 18x10 +35 Advan wheels fit flush with n An inside look at the completed quarter panel work and Spoon overfender.
