Schumacher LD3 and CAT PB Shared Parts List
If you race both the Schumacher LD3 and Schumacher CAT PB, you've probably already noticed something:
Many parts are shared between the two platforms.
That's one of the biggest advantages of Schumacher's current 2WD and 4WD competition buggies. From bearings and hardware to suspension and transmission components, a large number of spares fit both cars.
Whether you race 2WD one week and 4WD the next, or own both cars, carrying shared spares means fewer duplicate parts, a lighter pit box and faster repairs at the track.
Why Shared Spares Matter
Keeping a stock of shared parts offers several benefits:
- Smaller, lighter pit box
- Fewer duplicate spare parts to buy
- Faster repairs between rounds
- Better value when ordering spares
- Ideal for racers running both 2WD and 4WD
If you regularly race club meetings or BRCA regionals, these are some of the first parts worth keeping in your spares box.
