SPT Short throw VS KartBoy

Hey guys, I've researched this for a while and can't seem to get any proof on the differences between the Factory STI short throw and the KartBoy Short throw


I've heard the KartBoy is 30% shorter in throw and about an inch shorter in height, but I think thats comparing to a regular stock STI shifter instead of the SPT short throw.

I was looking at a COBB short throw as well since its height adjustable.

Can anyone tell me how much different the KartBoy and COBB is from a stock short throw for a newer STI?

I just want to see what the differences are before I spend $200.

Also, I'm going to get KartBoy bushings either way.

I have a 13' STI hatch

Thanks!
