So I got the Anvil inner fenders installed and I must say, I quite happy with them. It's not a simple drop in but the overall fit is quite good. When I did the driver's side, I jumped the gun on thinking I had to re-drill some holes to get the alignment right but after moving to the passenger side, things went quite smooth. After completing that side, I went back to the driver's side with some newfound knowledge and readjusted everything and all the holes lined up quite nicely.
If I had to give someone advice on these I'd say to take your time and don't get in a rush to re-drill any holes. I did have to trim the inner opening at the back of the upper control arms on both side for clearance but nothing major. The additional clearance these things have at the outer wheel opening is crazy, they basically turn straight up from the mounting flange
I finished prepping it for the Drive Autox event tomorrow and took it for a spin. No craziness but with some hard 90° turns and softer shock settings, there's no rubbing so far. I'll know for sure after tomorrow! Here's a pic of the finished product.
