yeh those are parking sensors . Previous owner put them on NOT a fan. I did toy with the idea of a GT500 conversion but in the end decided that I didn't want to:
a - spend all the extra money needed for this!!!
b - have people thinking that I was trying to fake a GT500
next step will be lowering and then (possibly!) 20s and a Roush rear spoiler - obviously budget will dictate what/when etc
