Stock Mini overview
"Stock Production, Mini Utility - Vehicles built from a 2 or 4 wheel drive mini or mid-sized pickup or sport utility vehicle having a maximum stock wheelbase of 125". Vehicle must have been series produced in quantities of at least 5,000 units within a 12 month period and be readily available to the general public in the U.S.A. Vehicle must be marketed as mini or mid-sized pickup or sport utility vehicles."
Stock Mini is basically a carbon copy of Stock Full, but on a smaller scale. With millions of mini trucks on the road today, Stock Mini draws a lot of fans to the desert who are eager to see just how well "their" truck will do when pushed beyond it's limits.
One of the biggest misconceptions about a Stock Mini are that they're slow & inexpensive. Wrong, wrong, wrong! Building a competitive Stock Mini can cost well over $40.000, but the results are well worth it. In races that average 60 mph for an "Unlimited" class vehicle, a Stock Mini will come in at about 35 mph. Very impressive when you consider that the other 25mph cost anothable modifications that increase their performance far beyond anything your dealer has on the lot. The 97 Parker 400 was proof positive of that assertion, with the Andataco Stock Full F-150 finishing the race with an average speed within 12mph of the winning Trophy Truck!
Engine and suspension modifications are severely limited, and factory components must be used in most areas. The rules allow for mods like multiple bypass shocks, which contribute dramatically to the vehicles' performance.
The bodies of a Stock Full truck retain all the factory sheet metal, making them among the heaviest trucks in the desert. Contributing further are parts like the factory dash, which add to the weight, but maintain the "stock" nature of the trucks.
My guess is that you will see the FJ Cruiser going from stock to class 3 soon. Both classes run at about the same speed but you get a lot more option for mods. in class 3. It will be interesting because class 3 is mostly straight axle.
