I must admit, some of the terms used nowadays make me feel rather old though
I always understood tuning to mean adding 15hp to a 1.6 engine by using a number of methods.
Body kits are now classed as 'tuning' even though they probably produce more drag than anything else, and make the car slower.
The 'bad boys' these days also think a set of underrun neon lights somehow add hp to the car and increase top speed and acceleration
Anway, I'm going to continue with the original style, and model some rims that don't include the 'held-on-with-cable-ties' hubcaps. They'll be in the classic VW style though.
