help me build my first race car

thanks everybody for the responses, i was extremly excited to see so much feedback i have recieved already. after reading over everything i guess im going to focus on chassis work for now, then the rearend tranny and so on. how many point roll cage do i need if i plan to make a ten second car someday. i was planning on moving the leafs in and doing mini tubs. what all chassis things do i need to focus on. i would like to get this thing as built as possible for being a ten second car. again thank you for all the feedback and please keep it coming
