Major issue with fitting the drag radials. After converting over to the FE4 suspension, the rear sway bar drop links stick down quite a bit. So much that they touch the inside of the wheel. Unfortunately I didn't think to look at them before I rolled it backwards some. It initially felt like I had the emergency brake on but after double checking all the brakes and stuff I figured something had to be wrong. I wasn't thinking about those threads but didn't take long to find the problem. Gotta love the metal that accumulated inside the wheel.
Bust out the butter cutter and took off about about 3/4". Even then it still doesn't clear by a whole bunch. It should work though.
The wheels are definately used now.
Indented grove and all.
