5x100 or 5x130

[oasis57]

Hi,

I want to convert a 1975 Super Beetle (1303) with stock fenders (wings) to being able to use one of the current Passat wheels. The one set of Passat wheels which I like are 5x100's and the other set is 5x130's.

I will be adding disk brakes all around and I will be adding wider fenders (wings) first.

Is there something important to consider that a technoklutz like me hasn't in choosing.

Thanks,
René
