#31286 Ball stud washer - To achieve most setups and can be used for arm spacing.
#4617 Bulkhead shims - To replace plastic clip spacers.
#31558 6 deg caster block - To achieve some setups.
#1401 Turnbuckles - To use camber link in the shock tower setups.
#31262 Silver anti roll bar set - To achieve some setups.

To race non boosted stock classes you will probably also need a smaller spur gear.
