Fire Suppressant Systems:

A fixed system plumbed into the vehicle can give protection to the engine compartment, fuel tank and fuel delivery systems.

 

It is important that the system is serviced regularly.

Braking System:

With the increased weight the armour imposes on the chassis the original braking system quickly becomes overloaded, creating heat at the disc and calliper area to such an extent that it causes the brakes to fade at speed, just at the time you would rely on them the most.

Because of the added protection added to the vehicle, the original brake callipers, discs and pads are upgraded to allow them to dissipate the extra heat that is created from having to stop a vehicle that now weighs nearly twice as much.

 

Racing cars have long been plagued by overheating brakes and so engineers have designed brake systems that have the ability to dissipate heat a lot more efficiently than standard brakes.

Upgrading the braking system to race car brake technology allows us to slow down the heavier armoured vehicle without creating the type of heat that causes brake fade.

They’re made from a specifically developed compound formulated to deliver real heavy duty performance for all sorts of load carrying situations whether it’s the demands of city driving or the hard grind of off road travel.

Stainless Steel Braided Brake Lines to cope with higher operating temperatures and pressures of the brake fluid, it also helps for a better feel through the brake pedal.

Suspension System:

Shock Absorbers have to be upgraded with heavy duty types.

Heavy duty shocks have more oil and are setup to match the characteristics of the vehicle, if not changed the standard shocks would quickly overheat and become useless.

The Run-Flat Tyre System allows you to getaway from the danger zone with the wheels damaged by gunfire.

The primary benefit of using run-flat system is continued mobility in case of a loss of air pressure, either due to a 'normal' puncture or a hostile deliberate act or even a bullet shot while the vehicle is traveling at high speed.

 

Performance criteria are therefore in terms of distance and speed at which the vehicle can escape without becoming immobile and the steering control over the vehicle during this process.

Upgraded Shackles and fixing bolts are replaced. This is an area that can fail first in harsh conditions.

The Stabilizer or Anti-roll bar. This also has to be upgraded on an armoured vehicle again to take into account the extra loads imposed by the heavy armour.

Leaf Springs: Because of the extra weight of armour the rear suspension have to be increased in size by adding more leafs.
