For those inquiring.. We have a duner/play cage we offer and hinged doors have not had chance to get up on website yet.. We always recommend safety first which would include cage, doors, and harness seat belts. If your looking for performance depending on the year of car carbureted/efi you will need to do some clutch upgrades a dyno jet kit for the efi and new exhaust. Also many of our customers prefer the paddles for the dunes. We offer all of the things mentioned if interested or needing pictures and prices please email us email@example.com as we are not listed as vendor on this forum. Thank you everyone for the interest and those of you who recommended us.
