Building your own race car isn't quite as simple as welding together a tube frame, bolting in an engine and hitting the racetrack. There's a lot of work that goes into calculating spring rates and suspension travel, and that's before you get complicated steering and gearbox linkages worked out. Oh, and tyre pressures.
TINSI Race Cars is an Indian outfit that does some pretty interesting stuff; its TINSI-I race car is built using the same principles as the Formula Student and FSAE standards that university competitions around the world use regularly. Not everything goes to plan the first time, though, like this particular instance where the TINSI-I went out for testing and burst its two right tyres on the first low-speed lap. [YouTube]
