I've had a noticeable vibration on my 2025 TJH250L-GNZAZA above roughly 65 mph ever since I installed my Method 703 / MT Baja Boss A/T setup. I chased it the way you'd expect — multiple rebalances and a couple of realignments — and never got rid of it. Eventually I chalked it up to the cost of doing business on E-load Mickey Thompson Baja Boss A/Ts, which are close enough to an M/T that a little highway NVH seemed like a fair trade for sidewalls that survive sharp rock. Then @cruiser_ss396 put me on to hub rings as a possible solution. At $22.49 shipped for the set of 5 rings, it was an easy decision to give them a try - and after installing them the wheel vibration is massively improved; it's almost gone!
The short version of why they work: Method bores the 703 to a 106.25 mm center bore so one casting covers several Toyota hub sizes, but the J250's hub pilot — the machined boss the wheel slides over — is only 95.1 mm. That leaves about 5.5 mm of air all the way around, so nothing locates the wheel except the six conical lug seats. You hang the wheel, gravity drops it onto the studs, and the lug cones have to drag it back to center as you tighten. When they don't quite manage it the wheel runs eccentric — off-center — by half a millimeter or more, and on a heavy assembly that is brutal: 84 lbs of 703 and E-load Baja Boss sitting just 0.5 mm off the axis of rotation is equivalent to about 85 g of balance weight, roughly ten times what a balancer calls good. The rings are 95.25 mm ID / 106.25 mm OD sleeves that fill the gap so the wheel references off the hub instead of the studs, which cuts worst-case eccentricity to about 0.075 mm. They carry no load, though — clamp force from the lug nuts still does that — so lug torque still matters.
Install was super simple (though crossed threads on one of the hub bolts added some time and labor).
My first course of action was just to replace the damaged bolts, but after realizing I needed to fully remove the brake assembly first, I decided a thread chaser die was good enough. Note the bolts are M14 with a 1.5 pitch.
I worked the die backwards and forward on the bolt until I could fully tighten and loosen it with two fingers and minimal resistance. Then I took all 30 lug nuts (including the 5 security nuts) to the vice and ran a male thread chaser die into each one until they each had a smooth action when tried on the test bolt.
I highly recommend this product to any owners of the following Method Race Wheels: 312, 314, 315, 316, 318, 321, 323, 701, 703, 704, 705, 707, 708, 709-HD, 710-HD, or 712 with a 106.25 mm bore.

- Remove each wheel
- Insert each hub ring into the inside of the wheel
- Re-mount each wheel, tightening in a star pattern to precisely 131 nm of torque. I use a Quinn 58706 Digital Torque Adapter to make it easy, and my approach is to tighten each nut to 80 NM in a 1-3-5-2-4-6 pattern, then around again in same order to 131 NM each. After 100 miles I re-checked torque on each bolt (none had loosened)

and thought to myself well crap. I figured they were going to be some $100 to $200 price tag, not $10
