Why a matched set?
BSA manufactures wheels from 18 different molds, numbered 1 to 18. The wheels in your kit can be from any of these molds. You can see the mold number embossed on the inside of each wheel.
Problem is, each mold is slightly different. Wheels can have slightly outside diameters, different bore sizes, hubs and tread characteristics.
When every milisecond counts, you want each wheel to be exactly the same because small differences will make the car slightly off balance affecting speed. Just like the car you drive, your wheels should be "balanced" to get optimal performance.
Pinewood Pro Matched wheel sets contain four wheels, each from the same mold to give you optimal performance, balance and speed.

Tips & Hints
The axle slots that are cut into standard blocks are too tight for BSA axles that are .089" diameter. Small axle slots make it difficult to get your axles in straight. A #44 drill bit is .086", which I find too tight. Consider a #43 Drill Bit, which is a perfect match at .089" for a snug fit.
When adding Nyoil to your axles, "less is more"! Only use one or two drops per axle and wipe off any excess oil. The oil should not be run down your axle.
Don't attach feathers or big decorative parts that can cause drag. This will decrease your car speed
Using the tips on your website, Daniel's car won every race for his den, and won the district races. It seemed that his car got faster with every run. We have memories that will last.
I can't even put into words how excited, proud and happy my daughter was each time her car won. Worth every penny, plus more. Thank you SO MUCH Pinwood Pro!
