Flairs are for those who think too much is just enough. Ok, so I am that kind of person.

As mentioned earlier, something too much is just right. Here is a comparison between a 7 inches wide wheel and a 9 inches wide wheel with relatively same size tires. you can see how much wider and bigger it became with just a change of wheel width. With that much extra wheels, it will stick out of the fender just a little bit. (a lot!)

Test fit the flair first to see what you will need to match it up to the fender. Since they are made with light weight fiberglass plastic, a few pieces of masking tape work just fine. The wheel in this picture measures 17x7 inches and +40mm offset. It has a 1.25"thick bolt-on wheel spacer. The wheel sit almost flush with the stock fender. The new front wheel is 2 inches wider with a +35mm offset. It will stick out of the stock fender by about one inch. The flair has just about enough coverage with a few millimeters to spare.

Well, here is the hardest part, cutting the factory fenders! In order for the new big wide wheels to compress without rubbing, the stock fenders need to be trimmed to allow the tires to compress into the flairs. 

Besides the fenders, some areas in the front wheel well have to be flatten or trimmed to allow steering room. Notice the cut marks on the fender. It is the exact coverage area of the flairs minus an inch of margin. Also, this is a good time to mark the rivet holes for drilling.

Marked areas  are cut into pieces and removed. Notice the 1.25" wheel spacers and vented disc rotor.

The rear fenders are two layers complete with inner wall. It will need to be trimmed twice and weld back together. You can use a mig flux welder or a tig even if you have access to one. Either way, you will have to rejoin the two or you might run into structural integrity issue.

Having a welder as a friend is invaluable in situation like this. Obviously, if you must do it yourself, be careful and don't get burned.

Riveting the flairs onto the car is a cake walk comparing to all the rest of the prep work that leads up to this. The flairs rivet holes are not pre-drilled, so drill them before applying paint.

Finished!! The entire process took 14 hours.
