not really, same concept except for curb feelers are for your wheels. its not like iam actually gonna use this sometime. the reason why i want it because the last show i entered my car in and i couldnt take the jdm class cus there was a ek with these and he won by a few points cus of that. the reason why i want it so maybe i can have better luck next time and come home with a 5 foot trophy. i didnt think it was a big deal at first but now i know how much it matters for judges at car shows.
