The TB bumper is worth a good deal more than most other bumpers, so if you do find someone to trade I would ask for trade + a little money on their end. A brand new painted TB front bumper goes for around $1500. A used one will go for whatever someone will pay for it. The thunderbunny kit looks good with all bumpers and many people mix and match. I have a votex lip on my rabbit with thunderbunny side skirts and votex rear. Personally I would keep the thunderbunny bumper because it is fairly rare, especially to see them on Jettas. I don't know the difference in ground clearance between the TB and r32 fronts, so I can't really help you with that question.
