I am a past ITA RX-3 guy. Been out of racing for about 7 years. I am currently thinking about building a RX-7 for either Spec 7 or ITA. With the RX-3's, I had to have custom cages built. I managed to total one car. My question is are Autopower cages any good, does any one have any better recommendation, or is a custom cage better. Thanks for the help.
