I have not been on track for ~ 5 years. planned updates to the 1985 CRX si are:

new aluminum seat with seat back brace.
new belts dated 2005.
new SA2000 helmut to replace SA1990.
new nascar style door bars (may do some honda challenge).
updated ITB lettering and 14x6 or 14x5 wheels to replace the 14x7's.

planning to do the updates and go to an annual tech event.

any other obvious omissions that I need to address?
