@Impala posted:I believe original VW pans are about 18 ga. It’s a good suggestion to go with at least that much.
18 ga steel is .05". VW pans are flimsy and rely on the assembly for strength. I haven't measured the pan thickness but would guess they would be 22 - 24 gauge. In Speedsters, seats and sliders will cause the floor pan to stress fracture over time. You will want to add some reinforcement where the mounting bolts will go.
18 Gauge would be a good choice for the floor. I doubt any of the aftermarket patch pans are that heavy.
