what everyone has said, if it snows where u live, u might want to have it on during the winter.

 

hi guys. i just got from my friend this one.what do you think?
should i keep it on ,or go better with the oem factory plastic one?
or modify this one from aluminium little bit
thanks

 

I would definitely keep this one, looks great

 

yes looks not bad,but today i weighted it ,and its 30lbs.i think its heavy.i need to get some ideas to replace it with something lighter

 

Carbon Fiber, that big metal plate itself could be used as a mold. Just put release agent on it and epoxy the carbon fiber on it, dry it, trim it, and peel it off and you have a CF identical piece that probably weighs a few pounds. Well that's what I would do.


I just keep my oem tray on. I'm gonna buy the cheap Chinese undertray clips off ebay for next time instead of buying $2 each from mitsu....

 

Try Alumalite. Its very strong, very lightweight, and isn't nearly as expensive as carbon fiber.

 

Aside from getting a lot of dirt under the car the only thing I have ever noticed is a little bit of lift in the front end when exceeding 100mph. (on a closed course of course)
