I have a couple hundred bucks to invest on the 500 and from everyone's experience i was wondering if you can help me out as far as should have some eibach pro kit springs installed or lower control arms? I'm leaning towards springs since it will visually improve looks and handling as well. Will the LCA's improve dramatically on wheel hop or do i need the uppers as well? Also, are LCA's something that can be installed in my own garage without any special tools? Can i just unbolt the factory's and slap on the new ones as simple as that or should i have them installed? Also, what LCA's do you recommend?
