Guessing this is what I would need

I thought Ariel asked him to not make any more Atom parts.

Anyway, think of jumping to slicks after a season or two of driving the Atom.

Ariel really doesn't have much to stand on here to make that kind of statement. They were/are his own design and are not copies. At least that is how I see the upright issue.

Tom's were the best looking uprights plain and simple. They almost looked to good to install

I ran the brammo factory uprights with hardened spacers on my 2007 "Doc" Atom2 on wide (13") sticky Hoosiers with no bearing or upright issues for two years(about 20,two day track events) I had a spare set of Palatov uprights and swapped to them just because stronger is always better..and the stock uprights removed looked new. I think the factory uprights would be fine if the spacers were hardened,and axle nuts were checked for any play regularly..as in a couple of times a day when at the track. Mine never came loose.

A couple months back I visited the TMI factory, and we got to talkin' about long-term ownership. It was their opinion that prior problems with rear hub/bearing durability (on USA Atoms) would be remedied by the hardened spacers alone, and that upgraded uprights weren't required to solve that problem.

Depending on what bearings were used on the Brammo cars, there can be bearing issues. Some of them were not internally sealed and had external seals which could leak - the normal sign of this was red/purple grease visible in the area. Both the Palatov and Unique replacement uprights include bigger bearings, and I know Tom/Unique was very specific about the exact brand/model used. I assume Palatov was the same way.
