My friend and I are planning on building a car to use in rallycross and clubrally events in the future. we have been looking around for a suitable 2WD car to use, and so far we have narrowed our search down to a late 80's-early 90's GTI, a 1990-2000 Toyota Celica, or a mid-90's Civic or Integra. We have also considered a Subaru Impreza or Celica All-Trac, but most of the articles on the subject say to start out in a 2WD car. we would like to know which of these cars is the best starting platform (i.e. easiest to modify and tune), and what the most cost-effective mods for rallying would be. We are on a fairly tight budget, and may not actually start building until next year. any response would be appreciated.
