I seriously can't believe no one is making custom wheels anymore, as a niche. I have an undiagnosed condition where I start with the wheels, and build a car around them, every time. I won't consider building an RC, unless the wheels are right/available.
Would love a 356, real, or RC.
I still have the stock Tamiya VW rims, they're closer to the 356 Speedster wheels, and later model VW's, with all the little holes for ventilation. The early pre-'68 VW's had ventilation slots, usually just five large ones slightly hidden, between the face and hoop.
Rear wheel shows them well.

It's for that reason I never used these Tamiya stock rims, they aren't right for scale, early VW.

Let me know if you're interested in them, I have no attachment to them.
