May i make a sugestion , before you make time and sometimes large financial committments to set up a competition car which (MUST comply with all the general rules and also class rules), the DLRA has a class for blokes like yourself ,who want to try out salt racing and their street car , its called , street class ,it allows you to enter and run with a minimum of compliance rules up to 130 mph (210 kph) it allows you to see if its the sort of racing you want to stick with and if you catch "salt fever " you can progress to a full blown comp type car ,basically what you need is
a current state drivers license
a registered and road legal car
a snell 2000 helmet ( full face type )
a 2 kg portable fire extinguisher ( securely mounted in drivers compartment )
long sleeve jacket and long pants sturdy shoes
this is the best way to start ,and you can check out all the race cars and talk with the drivers , who can point you in the right direction .
hope to see you there in 06
