I have a 2zz only used for track days now and have removed (because they broke) all the under trays. I do notice the front lift at about 80mph and a general slightly sketchy feeling at high speed. I was think of trying to fabricate something from aluminium as others have done, also I have seen similar under trays for sale. Does anyone have any tips or rough guide of how to do this or would it be as good to source a stock replacement? Thanks
The undertray incorporates some small air dams in front of the wheels.
They do make a difference. In fact, I think the front undertray, as a whole, does assist the aero.

Have a good look at the beatrush one I guess..
I don't suppose anyone has a spare front under tray I could buy or a broken one I could try and mend? I have the rear one. I bought a plastic repair gun to try and fix it with.
You'll get one from J-Spec
Thanks will give them a ring
a bit late; my appologies.
The rubber lip from the FL help too.
Also adding air vents in the bonnet at the windshield side. This provides an outlet on the upper side of the car and thus having a double effect: Less under, more above.
