- Rear diffusor: MANY people want a cheaper alternative to the BMW Performance. If you could come in at the $400-600 price point you would get a lot of feedback.
- Interior trim: everyone loves this, lots of applications, reasonably simple R&D since you're just copying what's already there.
No offense to the vert people at all, but if you're worried about recouping the upfront money OP, stick to products that appeal to a lot of people (i.e. not vert spoilers).
BTW Thanks for doing this!
+1 there are simply little to no options for side skirts (bmw perf and thats about it) or interior trim (bmw cf and vinyl wrapping). These 2 will be instant hits..
