I posted this in the old forum but all that is gone before I could get the anwers I am looking for. I want to either buil my WRX into a PGT car with ability to bump up to group N in the future. Now I am deciding on the cage and I know about Avsport, Cascade, and Vt car but I live in So Cal and wanted some recomendations on cage builders. Secondly should I have the cage built to FIA specs since from what I have read on these forums people say the SCCA rules are a bit tricky. I have ordered the rule book but it hasn't arrived yet. Last what material sould I choose Chromolly (I hope I spelled it Right) or I believe the other is DOM. Also I have tons of pics of cages so I can find a good race shop that could build off of those I imagine or should just order one from the UK like safety devices or Sparco? Thanks in advance for any advice you people can offer to me.
