IMO This should be purchased immediately when dropping your car, esp if youre in the midwest!

So Blain, you think for dumped rides that scrape often these aren't a good idea? Not sure they would "give" like the OEM one would since they are more rigid. I know Johnnyone ripped his off recently.

^I know when the Honduh punted me into the median, I wish I had the aluminum one, it would have kept a bunch of dirt and crap from getting kicked up into my engine bay, and probably saved the front bumper... thou in hindsight, I got the HikkataDori out of the deal, so no complaints there

The way I see it, the more protection to the bottom of the engine, the better... what if that rock johnny hit wouldn't have had anything between it and the oilpan (or just the flimsy stock piece)

Very good points Ashley. I'll be getting the RareJDM one when its released soon.

According to Zspeed, on their website, the front of the shield uses a more-crushable metal to account for hard impacts. They say the shield is attached to the glass composite subframe, and without the flexibility, that frame could be damaged. So I think whether or not the shield will be a benefit or detriment to slammed cars depends on the likely point of impact. If the point of impact will result in the shield pushing into the glass composite subframe...then , but if the force of the impact is directed into a metal point of attachment, then less damage will likely occur

"The front part of the shield that bolts to the fascia is of a thinner aluminum so if you were to hit a curb/parking block too hard it willl buckle and prevent damage of the lower fiberglass core support it bolts to. "

better off the aluminum undertray, than the oil pan + oil pickup behind it

Heavy aluminium (thick so I've heard) mounted to fiberglass is never a good idea, then the fiberglass taking a beating daily will probably end with no belly and no front bumper.

^ that would suck i like my front bumper

id like to see pics of of one of these mounted to a slammed car, im curious as to how much clearance there actually is

There's actually more clearance than the plastic one in a sense. Since theres no compliance or flexing from the aluminum one, it stay tucked up and close to the subframe like its supposed to.

I'd like to say I'm pretty well slammed and its def saved me from some oil pan damage already.

And it would be kinda hard to take a picture of it on my car cause I cant even fit my foot under my bumper

Should be all good then, I dont see why anyone would be constantly hitting this thing hard, I think the risk of slamming your oil pan hard on something and having this protect it outweighs the possibility of slamming the pan hard enough, and enough times to crack the fiberglass composite subframe.. remember ppl it is a composite, its not like its aero kit fiberglass =P
