Bora .375” or .5” spacers

[MadLUX]

This is actually a pretty cool option. For a couple reasons. A .375" (~10mm) and .5" (13mm") put stock wheels at pretty optimal offsets for common upsized 33" tires that people run. Netting effectively 50mm off and 47mm offset respectively when used with stock 60mm offset wheels.

It's not by chance that the factory Rock Warrior wheel has a 50mm offset for the recommended 285/70R17 (32.7" diameter) wheels. This is optimal for suspension geometry scrub radius, and will allow larger tire fitments to work and feel most like stock. Without subtle untoward behaviors that compromise handling and traction.

Provided the studs are long enough and engage enough threads on the lug nuts, these may be more desirable than using adapters.

1" spacers are more appropriate for 34-35" tires.

I have a set of .25” Bora spacers on order. I spoke to the guys at motor sports and they said they would be ideal for stock lugs. The biggest thing will be whether or not .25” will give me enough space to clear my UCA’s. It’s going to be close. I’ll report back once I try them out.

when you say 3/4" bora spacers work with stock LC wheels, please state the year of the stock LC wheels. They do not fit without stud trimming on 2016+ Base LC rims. I have not tried them with the 08-15 rims.

I have a 2016 LC 200 with OEM wheels and 3/4" bora spacers and they fit perfect.
I am not the first person on here to do this, I learned from others.

There is no need to stud trim.
There are dimples in the OEM wheels and the studs fit in the dimples.

Jusy FYI

I believe that's the hiccup with using traditional spacers on stock length studs. I know someone had 10mm spacers made up for them and they found they did not get adequate tread engagement because our studs are fairly short. I believe our studs are M14x1.5 (correct me if I'm wrong), which would require 9.5 turns for proper thread engagement. So if someone wants to try, please report back with what you find, but I'd suggest starting small.

Everything I’ve read says 7.5 for the 14x1.5. You can get that with their .25” spacer. Rumor has it Monica runs .25” spacer at Baja with no issues.

Had to trim the studs with 3/4” spacers for steelies. No big deal. Takes about 5 minutes per side

Good deal. I got the 9.5 number from Driven Products, one of the larger international suppliers of all things lug nuts and spacers.

Are you absolutely sure that you had to trim them?

Sure the studs stick out a little but they don't touch the OEM wheels.

Don't the steelies also have a dimple just like the OEM wheels and fit on without trimming. They appear to have a dimple.

The steelies don’t have much, plus by design they deform a bit when torqued to 150 ft lbs. It looked to me that they were barely touching the stud. Better safe than sorry when dealing with spacers IMO.

It is not going to hurt trimming them down in your situation, but I don't think it's actually needed. Torque on OEM lug nuts and studs is 97-100 if I remember right. I'm not sure the gain or risk is in going to 150.

After I read about all the other 200's it seemed 3/4" was the idea spacer to go with for up to 34" tires.

Torque on steelies are 154. See the line above the highlight straight from Tundra manual.

@MadLUX did you ever get the .25" spacers mounted up? Still would love to know how much thread engagement you got!

I tried them…. Still didn’t fix my rub problem and I was 1 or 1.5 rotations shy of what was recommended. I don’t remember exactly what was recommended, 7 or 7 1/2 rotations and it was definitely shy of that. So the spacers are sitting on a shelf in the garage and I switched so a more narrow tire.

Thanks for the follow-up. Bummer on the rub! Do wish our stock studs were longer.

Remind me what tire size you're trying to run?

It was a Baja boss 285/65/18 on a tundra TDR wheel. There was another guy on here running the exact same set up on his 2018 I believe with no rub. Not sure what changed on my 21 but even adding a quarter inch spacer it was still rubbing the UCA. The LX is my wife’s and I just wanted a second set of wheels and tires to put on for when I“borrow” it for the weekend. Since then I’ve added a new tundra to the arsenal and the Baja bosses are currently getting set up to go on it.

Wow, for the same 285/65R18 tire, the Baja Boss runs big. Really big! When compared to a commonly fitted KO2 that classically runs small, but looks like the KO2 is pretty nominal in this size. I threw in another tire, Toyo AT3, for comparison. Now I'm understanding why you're seeing rub.

285/65R18 Spec sizing:

Tire - Diameter, Section Width
Baja Boss - 33.2", 10.9"
Toyo AT3 - 32.6, 11.5"
KO2 - 32.6", 11.5"

For a 33.2" tall tire, a .75" spacer/adapter might be a better fit.

Here is the Baja boss. I went to a 275/65 K02 and had all Kinds of room. If it was my primary vehicle I would have done the bigger spacers… but where it’s my my wife’s car pool vehicle didn’t seem necessary to go the spacer route.
