i got my illuminas and tokico springs in pretty easily... the only problem was getting the bolts off. I think you need 9/16", 17mm, and 14mm. its the 17mm ones that are a real b*tch. just use a breaker bar and savce yourself several hours... and plenty of WD40. i didnt use a spring compressor. i just followed the advice on vfaq.com. it wasnt too bad, and i did mine alone. jack stands help a lot. -Irfan
