Does anyone have them? How hard is the install? My friend needs to know because he said that they are a requirement for some sorts of racing?

 

they are more tedious than hard, have to cut part of brake sheild to get to back of hub, then pull them thru slowly, at least if you use morroso studs like I did, if you use skunk or "z speed which I heard suck" then it should be like replacing stockers.you only need extended studs for dragracing as far as I know, if I am wrong correct me,good luck Jason
