Pinewood Derby BSA Blocks for Pinewood Derby Cars Pre-drilled Axle holes and original slots


All 100% BSA original PWD blocks with slots for standard wheelbase. In addition, there are holes for an extended wheel base and a slightly raised hole in the right front so that only three wheels touch the track for less rolling resistance. (I have found this to be a successful design) This allows you to utilize any version that your required to based on your local rules. All blocks have a hole drilled into the rear of the block that allows you to add my machined weight. (2 slots, 5 axle holes, and weight hole in rear)
