I have never run the RSG springs in the rear, so I can't help on the comparison. although for what I have into everything I should have just bought dave's lift from the beginning!

as far as tires, I am running 30 x 9.50 x 15 . they are retreaded tires. They used a triple sidewall bfgoodrich A/T carcass, and AT's usually run a little shorter than the specified height. so with the tire being retreaded its about 29.5 inches tall. I have no complaints on power or anything else as of now with these tires.

like I stated before, mine was a pain to get together due to the lower fork bolt not coming out, this would have helped a lot, but I got it together so thats the most important thing.

I am happy to be lifted again, and I like the RSG springs up front.

at full flex in the rear, the TJ springs I have are at about there max extension. with a jack under the frame, the TJ coil on the drivers side is loose, so I know there is still room for more lift.

I don't have any issues with the tj's though, they ride really well.
