Driver, say, in German car association (8)

I believe the answer is:

golfclub

I'm a little stuck... Click here to teach me more about this clue!

'driver say' is the definition.
(driver is a kind of golfclub)

'german car association' is the wordplay.
'german car' becomes 'golf' (I've seen this before. I am not sure about the 'german' bit.).
'association' becomes 'club' (club is a kind of association).
'golf'+'club'='GOLFCLUB'

'in' is the link.

Can you help me to learn more?

(Another definition for golfclub that I've seen is " iron?".)

I've seen this clue in The Irish Times.
