This is when i had ARB problems, i lowered it further when i got my new ARB
sorry not that low compared to VAG-Slag's one...same height, different size rims.
What size are you rims then, thought you said they were 18's? . . .
just to add... the rolling radius of 18's with 225/40/18's (which i think most have and what i had, not 205/45/18 as i previously stated) is almost i identical to the rolling radius of the standard 16' sport rims with the standard tyres (what ever size they are!?) so the tyre will be sitting in pretty much exactly the same place in the arch on both 18's and 16's
