I agree there needs to a little bit of change up in how the categories are defined. Retaining a 3 tier structure for the stock to lightly modded rigs, modded rigs and the heavily modded rigs and being sure to cross your t's and dot you i's with defining what constitutes each class.
Stock to Lightly Modded Class: Anything from bone stock to simple bolt on's like lights, cb's, wheels, rock rails, racks, etc. (There are plenty of people who have no interest or resources to move beyond this level so why eliminate the class.)
Modified Class: Any mod's that change the suspension, tires bigger than 32", bumpers, winches, etc.
Heavily Modified Class: Axle swaps, engine swaps, cages, stretches, tires bigger than XX" tall, etc.
Agree, I think this is the best solution. Keep the 3 classes with:
1. Stock to Lightly Modified: Simple bolt ons like lights, budget boost, possibly a winch (maybe even limit it to say 3 bigger mods like tires, a winch, and armor) anything more would bump up to the next class as being more than 'lightly modified'. Also tire size would predominantly be 33" or smaller.
2. Modified: Anything with 33-37 inch tires AND with multiple mods such as bumpers, a winch, sliders, a lift kit (thats more than a budget boost), wheels, lights, lockers, moderate axle upgrades, as well as other standard mods.
3. Heavily Modified: 37" tires and larger, a more involved lift kit to include stretches, coilover/bypass/resorvoir shocks, long arm kits, custom built lifts, frame cutting, triangulated 4 links, fuel cells, along with bumpers and all the usual mods. Axle, engine, trans, and transfer case upgrades would also fit into this category. (NOTE you might also consider breaking this category into two as its a pretty broad category but if theres only a few people who submit to this category each time it might be best to leave them combined...if you break them up I would put the jeeps with engine, axle replacement, custom suspension, and other 'extreme mods' into the higher up category)
