I've gone a bunch of different ways with my TJ over the years. At one point, I daily drove it with 4" lift and 33's. That got expensive! Now, it's pretty much a toy.
Currently, the TJ sits on 35's with maybe 6" of lift. I'm building my own long arms for it. The upper rear, I built a triangulated upper A-arm type set-up. The rear lowers use Currie johnny joints on one end and stock rubber bushings on the other. The rear suspension is fairly close to being finished. The only work left is to recess some new upper shock mounts into the frame and build some lower mounts behind the control arm brackets. I should have the new shocks this weekend, and plenty of time to work on the thing. So it may finally be back on all 4 wheels soon. It's been in the garage since November. The front end still needs to be designed and built. But I'm not sure if I want to go with a '4-link radius arm' or a '3-link+trackbar' set-up. So I may just keep the short arms on it for a little while longer.
I've built alot of stuff on the TJ... the winch mount/bumper, rocker guards, skid plates, etc. The engine is a 4.0L with an AW4 transmission (from an XJ). It's got Sirius radio, and a couple amps powering the soundbar and a sub recessed into the rear seat. The head unit is an Infinity Gold CD, taken from a ZJ (took way more work than just slapping it in). The axles are stock dana 30/dana 44 for now. There's way more...
The CJ7 is as bone-stock as they come except for a CB and a plow. It was my uncles Jeep. My kid will be driving this year, so we're rebuilding it together for him to use... The plan is to return it to 'almost showroom' condition. It may get an inch lift, so as to clear a set of 31's on a seperate set of stock rims (wheelin' tires). But otherwise, it's going to be an around-town cruiser on showroom tires.
The minivan is pretty new. It's my wifes. But my work is farther than hers, so I drop her off every morning. She won't let me mod it. But I have been hypermiling it when she's not around
I'm can get a pretty consistant 24mpg in the thing. The trip to and from work is about 50/50 city/hwy driving. So that's decent. She gets too nervous when I shut the engine off on the highway, so I limit that kind of stuff to when she's not around. Otherwise, I set the cruise at 55-60 and watch the gas guzzlers pass from my spot in the right lane.
The minivan is nice, but I'm on the lookout for a small car to just mod-out. Y'all have alot of great ideas! So I'm inspired (that could be dangerous).
