driving in the rain should not be a factor if you use a device to block the filters from direct air and have ALL of the stock splash guards. And third, I opted for the Blitz SUS Power Stainless Steel Mesh Air Filters for my Doolz to address the same concerns about driving in the rain. If the filters do get wet, they dry quickly. I have GT2530s and I don't have any low or high speed driving issues.
