Looking for lip that that goes under front air dam
 

Does anyone makes a lip that goes under the front air dam?

Are you talking about a splitter because most of the lips wrap underneath and bolt to the bottom of the air dam,,, if you could be a little bit more descriptive with what you are looking for Im sure plenty of people would be wiling to help you with your inquiry

^ok ok I was on my htc Diamond walking when I posted that.
Yes something like a splitter but thicker? Only if the air dam was 1-2 longer that would be fine but its not. So im looking for something that would get me there. Ill try to draw what I mean in a few.

well... read this page https://www.rx8club.com/series-i-exterior-appearance-body-kits-27/front-lip-152447/

then you have to pick what style you like... (ie: R-Magic, Burnout,Veilside)

search japanparts.com

thats much clearer, at first I thought you were asking about something that extended backwards into the undertray....
yup the popular ones are AutoExe, RMagic, Burnout, Veilside, some others more rare are RE Amemyia, Varis, replicas are Seibon, Shine Auto
Alucard has the RMagic, I have the Burnout type II....

Edit--- nukes right I forgot the Leg Motorsports, I would put that into the rare group...

don't forget about the ballin JDM Leg Motorsport lip.
