Go to
www.hondavision.com and READ their del Sol board. They are affiliated with Team Del Sol, so the guys know what they're talking about. Read through a lot of posts. Read all you can. Do a search on all the stuff you want to know. That will answer almost every question you can have. If AFTER you read and you still have questions, then ask them.
