Pinewood Derby Speed Wheels – Derby Worx Pro Ultra-Lites


The Pro Ultra-Lite Wheels weigh in at an amazing 1 gram each, and with 100’s of hours of testing on our track – B.S.A. Racing and a League Championships under their belt, you can be assured these are not just any lightened and weakened 1 race wonders. This set of wheels usually yield an increase of speed by reducing on average 0.03-0.04 seconds in time with properly tuned car. Listening to a set of these wheels run, you can tell they are in a league of their own!

Derby Worx® start with select mold number matched sets and C.N.C. machine them both inside and out to remove the maximum amount of mass from the wheel in all areas for maximum speed, but retain strength and durability. While the exterior of the wheel remains completely stock, all interior markings are removed.   They work well with all lubricants (graphite or racing oils) and feature a Reamed and Burnished hub bore for easier alignment and greater speeds,  plus both hub faces have been coned for greater friction reduction.

Set of x4 Wheels

Don’t forget to polish the bores to make the wheels even faster.  Reduce friction and micro scratches!  DIY or Let us do it.
