Congrats on the wheels monte. Glad you found a set. Did you get them from Germany?
The brakes are on the car (and have been for about 2 weeks)
but...
I'm currently running my old 19" wheels on the fronts due to spacer/lug issues.
I've been trying to track down some lugs that are 22mm in diameter to fit the smaller W12 bolt holes. Normally not that much of an issue, but finding 43mm long lugs that fit the spec has been a problem. I'll probably have to get some made up.
If anyone knows a place that sells them off the shelf (Cone seat M14 P1.5 43mm long and not wider than 22mm) let me know. Especially if they're a tuner/secure lug! I was running the Project Kics DPS lugs and they were great, but only come in 28mm or 35mm lengths.
So I've only got the W12s on the rear. It's the concave centres which have made the wheel require such a large spacer.
They still look really nice though. Big thanks again to Dave Brown for pulling it together and Pat for going to all that effort to get them down here to me!
As for performance, the RS4 calipers/RS6 rotors are pretty heavy in comparison to the Brembo GT 355x32 4 pots I had on there. It is a much more progressive kit than the GT and I am noticing the extra weight they're bringing to the front unsprung weight. I've not tracked the car with them on (nor do I really intend to being that they're white!
).
I do miss the immediacy of the GT 4 pot kit. For a performance setup, I do think it's the better balanced kit for car's power & weight. The geometry will also change quite a bit up front when the W12s go on. Especially considering that I've shifted a 42 offset wheel out an extra 15mm on top of whatever the rotor difference is (my guess is about an additional 3mm offset between the RS6/Brembo GT rotors alone). I did know they were a progressive kit, and expected the pedal feel to be much more OEM, but they just looked that good! If I'd upgraded from the factory setup, I'd be jumping hoops I'm sure.
My old 19" 45 offset huff reps didn't require spacers with the GT kit, and the RS4s required a 7mm spacer. There is a fair amount of play for flex in that spec though. Better safe than sorry and it's only a temporary measure till I get the right lug bolts.
The wider track should create more oversteer, but my car had already dialed out 'most' of what was there (and had a tendency to be a bit hair-trigger anyway, so it'll probably get even more tail happy. I've not properly given it the beans though as the wider fenders aren't on (still boxed in the garage), and I'm not keen on self flaring my OEM fenders.
All that said, I could seek out better pads which will improve the initial bite and I'll need to give myself time to adapt to them once the W12s and wider fenders are on give them the clearance they'll need under load. Should prove to be educational.
On a side note (well it is a photography thread really), I was sent one of these to shoot for the TID Styling site and was able to keep it for a small price.
