I'm looking for opinions on SFI 7.1 engine diapers for a Pro Mod If I run a ballistic nylon version then I have to have a belly pan on the chassis. Ive seen some carbon buckets that would be about the same cost, maybe a tad cheaper. What's everyone using these days? Pros/cons? I don't think I'll be pulling the pan after every one but I want something easy to take on and off when I do. Thanks!
