I don't really understand the ASS issue people have... I think mine is perfectly acceptable and if I'm not stopping for more than a few to five seconds the clutch remains dipped so no ASS activation - I appreciate the mechanics of it are different in an auto I presume tho? - surely you can just switch it off... A simple press after start, you've gotta hit start anyway! Lol ;-)
As for the lip spoiler someone found a seller on eBay...
Pics etc;
