I searched the forum for info on leveling kits and got some info but every thread i went to was different... so my question is which on should i go for? i found them for like 79.99 up to 139.99? i also heard there can be some vibration and what not, dont really understand just saw someone said that in a thread on this forum. So any info would be great! also do u need a compressor for the strut? and how bad is the job?
