Finally doing my lift

[4wordSOUL]

Finally doing my lift, advice on my choice/options?

My Runner is my daily driver but I want some wheeling capability without sacrificing too much in the way of comfort and decent ride quality on the road. I understand there are compromises to both...

I'm looking at the Toytec Boss 3" lift with the Superflex HD coils and Total Chaos control arms.

Thinking about these wheels:

LEVEL 8 MK6 17 X8 6-139.70 -10
LEVEL 8 MK6 17 X9 6-139.70 -12


I have a few questions:

Has anyone done this lift and what was your experience, what would you have done differently if anything?

If the MK6's are the wrong size and offset, what would the optimal offset be for my use case? What wheel dimensions would you suggest?

I'm going to use up the rest of my summer tires (265 70x17 Duratracks), when I replace them what should I consider?

Thanks!

just replaced my xreas with the boss kit and the super flex rears, made such a difference, since i got the HD rears it has some rake but will be level once my tent is mounted, i also got SPC UCA and at highway speeds i no longer have any steering wheel shimmy

I think you should reconsider and aim for a lesser lift if you actually want to maintain better street performance and to save the cost on arms. Personally I think 2" all around is a great place to be.

The more you lift, the less droop you have too. Extended travel shocks offer a solution to that problem.

If you consider street performance, I rather have less lift and more droop to work with things like pot holes... allowing the suspension to dip in vs the entire truck due to a lack of downward travel.

I've got a buddy with a 3" Old Man Emu lift on his FJ and I'm fine with how it rides on the street.

2" seems to be the perfect mid height lift for the 4th gen. When you get into 3" you should really start replacing upper control arms and other stuff so it adds up a lot quicker. The OME 2" lift is a great every day driver but decent weekend wheeler too.

That's fine if you know what you are giving up. Considering you mentioned its a daily driver... 3" is a pretty compromising lift for on the road performance, which is why I said you might want to reconsider it.

I was only trying to get you to think of design considerations for the application. As a rule, you should only lift as high as you need to fit the tires you want to run. You should actually try to keep the center of gravity as low as possible as the overall benefit to handling and stability can often times trump pure ground clearance.

That clearance comes at a cost, and that's downward droop. To get it back, cost money, and often times cost becomes the limiting factor to do it right. You only have so much articulation without going to a long travel kit. The more you go up, the less you can do down as the total travel of the stoke is pretty fixed. The goal is to keep all 4 on the ground... Droop is just as important as compression... for both handling and saftey.

I have the toytec boss kit with the 650 lb springs and stock upper control arms. It rides firmer vs the 600 lb springs but that's what I preferred. Minimal brake dive and much much better on the highway vs my worn out xreas stock suspension.
I don't have the coilovers at the max height to keep my alignment pretty close to stock. I would go ahead and get new control arms to take full advantage of the coilovers, I just ran out of money.
For Tires I went with Cooper Discoverer ST Maxx, 33s, and I love them. American company, and made in america. Had yokohama ATs before and they were poor for any serious wheeling. The Maxxs are a 10 ply tire, which means stiff sidewalls and they're heavy (58 lbs a piece).
One thing to note when you get 33s is that they will rub on the plastic fender liners in the front. It's easy to push the liner forward and drill them into place. Plenty of threads about doing this.

Hey OP my suggestion would be to reach out to one of the vendors on the forum, they are usually more than happy to help you get setup with exactly what you are looking for.
For example I recently found Dobinson Suspension here on the forum, and Mike was absolutely wonderful. I told him how I drive it (daily vs offroad), the added weight I will have constantly (bumpers, winches ect), and how much lift. We went back and forth on their springs rates, load ratings, lift sizes, ect, long story short he hooked me up with exactly the springs and shocks I need for a very reasonable price. Its and Australian company, but they have a distributor (Mike), in Miami. I too was looking at that Toytec kit, but ultimately went with what Mike had customized for me.
Haven't got it installed yet, hoping to next week, so I have no review on the lift itself, but there is an open recent thread about Dobinson.
