Opinions are like armpits -- everyone has a couple and they normally stink -- but I think a full-across, SRT style chin spoiler would sell more than anything else. You could even design it a bit deeper, but the OEM lines would serve to compliment you better. Not that these look terrible, but I know of DOZENS of forum members that want an SRT front bumper, but don't want to wait six months and shell out $450 (plus paint) simply to gain a chin spoiler.
If you could fabricate something that could
- add on to the existing N/A bumper
- wrap around the edges to look OEM
- extend deep enough to make it worthwhile, but shallow enough not to necessitate side skirts
You'd have a winner.
Mock-up should be easy... find someone that's willing to let their SRT wear a mold for a few hours, and isolate the chin spoiler area for the mold production. VOILA!
