363-Piece Premium Multi-Lane Marble Racing Track Set
The IMR Grand Prix is the largest set in the Impact Marble Racing lineup. With 363 pieces (283 track parts + 80 marbles), this is the ultimate marble racing experience for serious builders, families, and hobbyists who want maximum track complexity and the most intense head-to-head competition.
The Grand Prix includes every track piece type in the IMR system: straightaways, turns, funnels, bumpers, spiral turns, curved dividers, mergers, splitters, impact zones, pathway dividers, and swappable mod inserts. More pieces means more height, more lanes, and more ways for marbles to interact on the track. With hundreds of possible configurations, you can build massive multi-level racetracks that look and play completely different every time.
Step-by-step instructions and score cards are included, with five different ways to play right out of the box. Every piece press-fits together for quick, easy assembly with no tools required. It's built for solo builders, head-to-head matchups, family game nights, and group competitions, and suitable for racers of nearly all ages.
The Grand Prix is fully compatible with all IMR add-on packs for even more expansion. If you already own a Circuit or Speedway, combine them with the Grand Prix for truly massive builds.
Available in two themes: Overdrive and Redline.

FAQs
Commonly asked questions or concerns
Where can I see the shipping costs?
Shipping costs vary wildly depending on where you live. The best way to see shipping costs would be to fill out an order, go through the checkout, and before you have to commit to a purchase you will see the cost of shipping.
Do you ship overseas?
If you see your country appear as a shipping option at checkout, yes. Otherwise, no.
If you do appear, the costs still are only stateside. Once the order gets to your country, you will still owe any customs/border fees/or taxes when the product moves into your country.
