Ground FX Fenders differ in size?

Im putting some t/a gfx on my formula. Are the fenders different in size? It looks like the back part behind the wheel/infront of the door, is wider than the GFX that covers it.

Anyone else ?

No. They're exactly the same. I have a formula fender on the front of my GTA. You'll have to drill the holes though.

Hi Jim,

Weird.. Maybe I shoulda stopped drinking when I was visualizing last night.

Drilling the holes in the right place is gonna be a nightmare..

I imagine I could prolly guestimate where the brackets should go based on the hight of the front and rear bumper's inbedded ground effect, and then measure them out..

I wish there was a tech article on the exact locations of the holes. WOuld make life easier.

The part under the door is gonna be a pita.. I got the front and rear bumper on tho.. Should look nice with the red car and black effects.

if you have the old fender, or the fender on the other side of the car, you can just make a template as mentioned above and easily transfer the holes to the new fender.
