I was flinging screw drivers trying to get those off last time. Going to give this a try or use a beatrush underpanel.

 

i cant wait to get a beatrush, my stock one came off when i did the clutch and i said *&%^$ that thing! hasnt been back on since!

 

good work, i hate them damn things

 

ya, its redicioulous that I can get the front bumper off faster than the oem undertray with stock clips. It looks like there are about 4 clips that I might still end up using, the one on the lower subfame, and the three on the raised portion parts of the underpanel, unless I figure out something relatviely inexpensive. I also want to see if I can stiffen the undertray a bit, it just seems rather flimsy to me.
One reason I am doing this is to be able to easily remove the underbody panel at the track, and also to secure it a bit better for track duty. Once I get this panel secured how I want it, I will be taking measurements to make underbody panels to create a flat bottom, with maybe some diffusers.
