I've had my Z now for about a month, and I've already gotten 2 noticeable dings on my bumper from rocks and such.

From what I've heard, the 3M clear bras are nice, but expensive. eBay has some guys selling the clear bra's for less than $50. I can install myself, but has anyone had experience with these off-brand vinyl bras?

(search eBay for clear bra 350z for examples)

 

if it's not 3m... you're probably going to be wasting your time and money... 3M kinda "as good as it gets" remember...

you get what you pay for

 

Go to the site below for 3M clear bra installers in your area:

I had mine installed a couple of weeks ago. Don't buy the cheap ones on eBay and by all means, have professionals install them for you.

 

The install on these is much more difficult than you think. A major portion of the $350-450 cost of these is the install labor...
