right now i have the eibach pro kit springs on my 99 GT. ive been thinking about switching over to an eibach coil over kit. mainly cuz im looking for a bit better handling performance and id like to be able to adjust my ride height. am i going to notice a difference in handling or do you pay the extra money just to have the tunability of coil overs? i found this kit http://livermoreperformance.com/mustang_coil_over.html#eibach for $1219. doesnt seem too bad. do you know if these shocks have compression or rebound adjust as well as the ride height. im somewhat familiar with adjusting shocks from my ATV racing days so it would be nice to have a shock i can soften up a bit for drag racing and then stiffen a bit more for handling. do you think these will do it? is there a better brand out there? is there anything else i will need to buy along with the kit to get it to work right? or do you think i should just stay with the springs i already have?
