Designing a front suspension system for a car like the Maruti 800 involves several steps and considerations. Here's a step-by-step guide:

1. **Understand the Requirements**: The first step is to understand the requirements. In this case, the car is a Maruti 800, the velocity is 100 km/hr, and the total load on the four wheels is 400 kg. The suspension system should be a double fork assembly, and it should account for kinetic and damping energy. The design should also consider pitch and roll conditions.

2. **Choose the Type of Suspension**: Since we're designing a front suspension system, we can choose between several types, such as MacPherson Strut, Double Wishbone, or Multi-link. Given the requirement for a double fork assembly, a Double Wishbone suspension might be the most suitable.

3. **Calculate the Spring Rate**: The spring rate (k) can be calculated using the formula k = W/Δx, where W is the weight on the spring and Δx is the desired compression. Assuming that the weight on each front wheel is half of the total front axle load (i.e., 100 kg), and assuming a desired compression of, say, 0.1 m, the spring rate would be (100*9.81)/0.1 = 9810 N/m.

4. **Design the Damper**: The damper is designed to absorb and dissipate energy. The damping coefficient (c) can be calculated using the formula c = 2*sqrt(m*k), where m is the sprung mass and k is the spring rate. Assuming that the sprung mass is equal to the weight on the front wheel (i.e., 100 kg), the damping coefficient would be 2*sqrt(100*9810) = 19820 Ns/m.

5. **Consider the Kinetic and Damping Energy**: The kinetic energy of the car can be calculated using the formula KE = 0.5*m*v^2, where m is the mass and v is the velocity. The damping energy can be calculated as the integral of the force times the velocity over time.

6. **Design for Pitch and Roll Conditions**: Pitch and roll conditions refer to the car's movements around its center of gravity. These movements should be minimized for a comfortable ride. This can be achieved by carefully positioning the suspension components and by using anti-roll bars.

7. **Finalize the Design and Test**: After all these considerations and calculations, the final design of the suspension system can be drawn up. It's important to then test the design under various conditions to ensure it meets all the requirements and provides a smooth and safe ride.

Remember, this is a simplified guide and actual suspension design involves more complex calculations and considerations. It's always best to consult with a professional engineer or a knowledgeable person when designing a car suspension system.
