my friend did it himself in a couple hours first time also without any help and without the compressor, and I'm pretty sure u can remove the spring without it n let it shoot out into something relatively stable but a lil soft so it doesnt shoot back haha, i'm wondering if u need the compressor to put trd ones or if they're short enough that you don't
plus i had these kinds of questions with everything I did so far not many problems up till now

plus I get to work on my car myself heh
btw R07M i see ur in MA, know anyone who can do it cheap? best quote I got is 50 per corner or 60/hour, couple more people supposed to call me back with quotes but I dont thin kit'll go much bellow that, if I can find someone to do it for like 100 or a lil above I can otherwise I can buy al lthe tools and then some for that much and do it myself heh vacation is good for something
