I recently put the Panzer from DG on my 03 Jetta. It's nice. But I had to take it off because my suspension is original (113k miles), and I guess it's too spongy now to hold it up enough. I did not measure how much clearance I lost because of the weight, but I was scraping on things I didn't scrape on before. I reverted to the original plastic. Also, the handling and "pickup" of the car were definitely affected. My GF said it felt like the parking brake was on. I figure 11 years and I haven't had an "incident" so... But I will for sure keep it and when the time comes for suspension beef-up, I'll slap it back on and give it another try.
