Be carfull when you will set-up the bump stop. You need to set it at full flex, not when dropping the suspension on both side. You're tire when a full flex will get higher in the fender than when you're dropping the suspension on both side. When you flex the bump stop on the up traver side will act just like a pivot point, so even if suspension sit on the bump stop tire can still get higher in the fender because the other side is getting down. Here a picture that may help to understand (if you arent yet). for my jeep i can put my hand between tire and fender but no more. Also you don't need so much up travel, on my jeep i got 3 inch of up travel front and rear. You need way more down traver than up. For the coil spring, i would suggest to use the cherookee one. I run some front Tj's 4 inch coil spring on front axle and oem coil for the rear. The ride quality is awsome. Here's a picture of how i mount my coil spring on the front axle. Cherooke and tj on the upper part have the last loop with a smaller diameter than the rest of the coil, using poly bump stop i center the coil on the coil bucket. For the bottom i just fab a cylinder that goes inside the coil so it can move and always stay in the center. This way you won't need to attach the bottom of the coil. Also another avantages is the fact when you flex you don't have a too long bump stop that will get in touch with the coil spring. On jeep tj when folk's put 4 inch coil they just put a spacer on the bump stop and the problem occur.
