my fave 'bang for buck' mod has to be rust, costs nothing

best eve raftermarket part i'd probably say my exedy stage 2 clutch on the celica.
Then I'd say my white steering wheel in the Shuttle.

Best value. the custom shock top hats my dad made for me. totally free

ive got afew realy me pair of bride seats me golden eagle oil cap but my favorite of all is my parkin pole and how many folk ask what it is lol

i'd say my FM short shifter for my prelude

Hks Racing suction hard pipe induction
