i was gonna buy some koni yellows from jegs and do my rear today i assume its not to hard
no its terribly hard persay, but depending on what springs you have you may or may not need a spring compressor
I didn't need one for the rear on my sportlines,
I just used the spring compressor on the fronts.
backs are pretty soft
I put Eibach Sportlines in mine last week no compressor need for the rear
i didnt use one for fronts nor rears. they arent needed.
hell.. they arent even needed to remove the stockers off the rears. just impack the nut off and they seperate just fine. i thought it was dangerous as hell until i saw someone actually do it recently. now the fronts.... i dont know about. wouldnt recommend it. though.

I'm tired of wasting my time... now I'm breakin' free.
