Title - not requiredto race, but nice to have for resale and street use (since you want to develop as you drive).

Log Book - required to race. Fairly easy to get. Call you local tech inspector, set up a time to get the car checked, and if it meets all the GCR safety rules, he'll stamp the rollcage with a number and issue a logbook. BTW - if you are building a car from scratch, contact your tech guy early, they usually have good advice about the safety gear.
