How to modernize this car

The biggest problem with this car is not its styling, or the interiors. The biggest issue contrary to popular belief is it's safety. The biggest misconception is that safety is in size. One argument can be that the safety at city speeds is adequate. However today when modern cars and suvs capable of driving at high speeds, and with a young rich kid behind the wheel, doing crazy speeds are getting common, this car is just not capable of handling the impact against these highly engineered vehicles with superior high strength steels and collapsible crush zones.

So Instead of focusing on the interiors and styling; which incidently is the main appeal of this vehicle, I suggest the following upgrades.

Modify rear suspension to one with coil springs and shocks. maybe a twist beam or a simplified multilink rear. This will improve cornering and stability.leaf springs are for trucks.

Upgrade brakes to disk on all wheels and maybe add ABS

Upgrade tires to get better traction and performance.

Beef up the green house structure by adding a smart roll cage.

Down the road more power can be added by making engine and exhaust modifications, for added torque to help pass other vehicles in deadly indian one lane highways.

These modifications can be achieved by a smart mechanic. I believe  this  vehicle will be a great seller. Safe, historic, comfortable and the ultimate identification with indian heritage; and will be cool to own.

This kind of kits are very common is US where similar cars from the 60's and 70's are hugely popular for their emotional appeal.

Let me know if there are mechanics who can do this.
