The same regulations as for the regular category apply, except for the possibility to completely replace max 2 out of 5 vehicle components.
1. Body
- You may replace the body with another vehicle's body.
- You may shorten the vehicle between the axles.
2. Frame
- You may replace the frame with another vehicle's frame.
- You may bob tail it or extend the length between the axles.
3. Drivetrain
- You may replace the complete drivetrain or just a part of it.
- You may replace a diesel engine with a petrol one and vice versa.
- You may replace a drivetrain with another vehicle's one.
4. Suspension
- You may change the suspension in any way you want, including suspension brackets, "short arm" to "long arm" conversions, coilovers, etc...
5. Axles
- You may use any axles you desire on any vehicle.
- You can shorten them or extend them.
Additionally:
- All vehicles can use tires up to 35", however you are allowed to use 37" tires for example, but then it counts as 1 of the 5 allowed modifications. You are then allowed to make just one more additonal component change from the allowed 2 out of 5.
As stated before, you can replace just 2 out of 5 components, so for example:
- A Suzuki with Nissan axles and "long arm suspension" has to have a 1300cc engine :)
- A Wrangler with a Vette and Dana 60 must have "short arm suspension" , etc... :)
