So how much did it drop and how does it look? Here are some not ideal photos I could take at the moment (from a photography point of view) but they do ok to provide the comparison:
For me it's almost perfect. The front is exactly as I wish it would be: 20-25mm drop measured.
The rear seems to have dropped more (in comparison) a 25-30mm in total. As stock, the rear was sitting 10mm higher than the front (clearly visible on the top part of the photos), now both ends sit at the same height.
This looks pretty sweet I have to admit as the car sits level now, but I wonder how it will be once fully loaded with 4 people and luggage. Need to check this. For sure, if i hadn't opted for the 6.5mm thicker Audi TT bushings I'd be in trouble and the rear would be lower than the front so my recommendation:
If you have a 272, you most probably need the Audi bushings too (they were 16 EUR in total)
A couple more:
I have to say I absolutely love the look of the car right now with the wider alloys and the new ride height, clearly purposeful and as aggressive as it should be (for what it is with near 400bhp) without getting too extreme.
But the best thing was the handling improvement. I really didn't expect that amount of change as I've experienced in my first test drive an I can only attribute it to the Sportline's DCC set up which, has to be different than the L&K's otherwise my findings simply don't match the ones from L&K owners at all.
As short as I can put it, the springs almost eliminated the effects of weight transfer during almost every change of balance. Gone is the squatting during acceleration, the brake diving and the bit of initial roll still left even after the arb upgrade. In Sport, it's a real performance machine now but the weird thing is that the comfort hasn't been compromised at all. The car turns in and corners almost flat, and what I noticed is that the point of the thicker arb's intervention became imperceptible now. No more "bit of roll - then lock yaw" behaviour, just an increased opposition to roll right from the start and much more tendency to follow whatever your input is. Driving it "blind" you would have to assume it's some focused GTI and I did live with one for 3 years so I have a good reference I think. The exploiting of the extra power now is so much nicer, you don't feel as if you're forcing the car to do something too hard but rather something it was designed to do from factory. Everything just works better and doesn't stand out. Obviously the Sportline's damping (on Sport) was set up right from the start but the stock springs were the weak link letting it down. I can't explain it any other way.
I'm usually picky with suspension and handling and as it stands, changing the dampers doesn't even cross my mind, it's that good now. On the other hand, if you don't have a Sportline DCC and decide to change springs on your own, do yourself a favour and put some new shocks in (Koni Actives got great reviews recently here) while you're at it. The thought of having to do that if my DCC-springs combo wasn't up to the job made me dizzy, thankfully it wasn't the case on my car.
The only other thing needed now is brakes I feel. On an open road, you are now getting so tempted to attack anything not in a straight line and once you do the limit has been raised that much that you find yourself needing to stop from higher speeds way more often than before. So it's something that needs looking at at some point.
Overall a great transformation into something so much more potent and enjoyable helped by all new bits in place, looking forward to just find time to drive it now...
