I'm going to assume you're not thinking about a front spoiler or splitter. But if you are I would look into the front hinges That John and Mark did in the #48 build.

The other area I'd be a tiny bit concerned about is the rear track width I'm thinking more than one of these builds has needed spacers on the rear wheels. I'm not convinced FF has the right length on the control arms and half shafts

But I'm more than confident you will work through any issues with an elegant solution again can't wait to watch
