Lift Kit Questions

[BlueMagicSS]

I know this is more of an opinion but I've been looking and need a little help.

I'm planning on doing a lift on my 89 K5 and I want to know which is the best kit. I'm looking for a more streetable kit as I won't be doing too much off-road, more of looks. I'll probably tow my car to the track or a boat a little later on, but looking for more of a comfortable ride. I know that it won't be stock because of the changes, but what would you suggest?

I want Leaf Springs in the rear not blocks or add-a-leafs. Dual steering stabilizer and a decent ride. I've looked at all the kits on rockymountainsusp.com and say that the 6" Kits clear 37's. I thought that 6" would only clear 35's? or does it depend on the kit? Also which upgrades would you suggest at the same time? Thanks
