I'm looking to convert my 17mm buggy to Genesis 19mm wheels/tires. I was told by Cen racing there is no conversion.
I looked onto Proline for the 23mm conversion, which looks great but the wheels/ tires don't look as big of a series as the genesis wheels.
Any suggestions?

Maybe you could epoxy some ~1mm thick strips of metal or plastic inside of the Genesis wheel hexes and a large washer on the outside if needed?

How do you plan to turn those tires? Buggies would need a bigger spur to get the right gearing...

If you want though...since the Genesis uses 19mm you can use the old Inferno 6 19mm hexes. They are just like the 17mm you have now only Kyosho tried 19mm for some short time.

Thanx for the options. I'll let ya know what works.
