First off, welcome to the forum and your new rig!
Second, what I've written below is not to be drag or bummer, but a reality check for you.
Any reason you haven't just bolted them on in your driveway and rolled around the neighborhood to see how they feel and look?
This will answer most your questions you've asked and not have to worry if the info you're hearing on here is accurate or not.
The short answer from me, note this is my opinion:
Do not use spacers of any kind, either to lift your rig nor to push out your wheels.
You and a nice rig, it's a Lexus for heavens sake! Spend the extra cabbage and do it right.
Reasons:
- Doing a body lift, you'll have to deal with your radiator, shifter and other components having to be adjusted. Plus you'll see the vehicle's frame. Just doesn't look good.
- Doing a wheel spacer,I consider just plane unsafe. You'll need to do regular torque setting on the spacers bolts to ensure they haven't come loose. You're much better with just getting the right wheels and tires.
- Most anyone on this forum will attest that aftermarket suspension gives a better ride than stock if properly researched for the correct suspension for the build (or lack of build) of your rig.
Do it once and be done with it. The old adage: "buy once, cry once" is very true in this sport/hobby.
I really hate to be the person to be that thunder cloud over your parade, but I'm assuming you want the truth from a person who's built three overlanders over 30 years, including my current one here:
R²M 2013 GX 460 Overland Build
So I know a little of what I'm talking about.
