Thanks for the comments guys!
1. The wheels are WORK Varianza T1S 19x8 custom made due to the offset
2. They are about the same weight if not lighter
3. Same rolling diameter
4. That time was on stock wheels but its lost no performance but as I bought the car from the Docklands and having it dyno'd at 145kw @ the wheels people tell me its probably got a V-tune.
The car has been mistaken for an RS4 but the guy was a bit of an idiot.
Oh btw the Tanabe coil overs at that height are more comfortable than the Bilsteins and handle no differently
It was a 5 month project to select the suspension and get the wheels right and it wasn't cheap. They would be even more expensive now the Yen is so strong.
Only plans at the moment are to get tint to match the privacy glass
