IMO for reasons i find not suitable the only Coils i wont get at this point is NGM. They work fine for most, but not for me
KSport is a very nice coil.. Just a bit hard to adjust the back when needed.. However if your a daily and want to go to the track here and there i would just set the rear at 10clicks(Actually i think im at 15 clicks in the rear as a daily) and forget about it.. Throw a torsion bar on there and the back will be pretty sweet..
For what its worth what ever coil you buy make sure the mounting point for the rear shock is the same as stock. Meaning the eye that the bottom bolt goes through is Under or inline with the shock. COils like NGM are mounted with the mounting point above the bottom of the shock.. I see issues in the long run with this type of mounting system.. Now i know there are a million different views on this, Do your homework and buy whats best FOR YOU and the budget you have to work with..
Happy modding!!!
