Hello,
Im just in the process of purchasing a 350 wiv the nismo aero pack nd extras. Where I am located there are blasted speedbumps everywhere and just need advice if they will cause any scraping to the underbody and bodywork. Cheers.

 

The most likely place to scrape is the underside of your front bumper, there is an air deflector thingie that hangs down. But you won't scrape that on a speed bump, probably only on a steep driveway. The Z doesn't sit that low, most people can afford to lower it a little bit, like 0.7"

 

I have a tendency to scrape the stock muffler when I'm going up an inclined driveway entrance, at the point where the incline ends and the leveled parking lot starts.

 

my pre mufflers are dented in a little bit on my nismo exhaust Y pipe

 

Cheers for the advice cant wait for it to come the dealer sed it wud take between 1 and 3 months to arrive which sucks just a bit but im sure its worth the wait.

 

You should be ok.

 

Watch out for those concrete stops used in parking lots. Their higher then 4.7 inches!

 

I think even 4.7inches would mess my front up...
I scrape sometimes cause my car is so low from the bodykit.

 

I barely scrape the middle of the underside of my Z driving into my underground apt parking structure (I'm dreading the day I have to look at it). but I'd def watch out for those parking stops, I misjudged how long the front of my Z was when I first got it and scraped the front bumper on one of those.
