Thank you for your interest! I'll stick to the same format to answer your questions
1. We do not have a Rubicon so unfortunately it's tailored more for the Sport model. You will have to live with the gaps, or just replace the fenders with ours when they come out

2. We will not be offering a stinger for the fullwidths unfortunately.
3. The Destroyer Sliders for the JL will be frame mounted like the Signature, so have no fears!
4. We do want to make a roof rack, but it's probably at least a half year away in the future realistically. So while we will get there eventually, right now we only have the JK rack.
