Grand Precision was started because many diecasts in our personal collections were still missing aftermarket race-specific decals.
Rather than settling for inaccurate or low quality decals, we set out to provide conversion decals that would be praised by the most discerning collectors. Before production, every silk-screened decal sheet is painstakingly applied to the base car to verify sizing and to ensure accuracy as close as possible.
Since our inception, our dedication to accuracy has expanded beyond silk-screened fill-in decals to include 3D-printed resin parts and full-car decals for custom builds.
October 2023 Update: We've partnered with Print It Decals to offer the best printing options of our full Indycar decal sheets. Payment and fulfilment for these sets is handled from Print It Decals and would require separate payment from any items ordered from Grandprecision.net.
Disclaimer: The diecasts shown on this website are offered by various manufacturers. The decals are sold as artwork to allow the diecasts to reflect the original cars accurately. No ownership is claimed of any cars, designs, texts or markings.
