I've been trying to get a hold of South West Lotus Centre in the UK for some front brake rotor rings, since their prices were the best I've seen (WAS roughly $200/disc + shipping, for the fronts).
But, looks like AP racing no longer makes the rings:
The original drilled AP Racing discs are no longer available for the Noble Car and the Grooved Front Discs are also being discontinued. Noble are looking into producing a floating disc system which will replace all the previous brake discs supplied. As the intial disc will have a black bell fitted the cost is likely to be in the region of £422.50+VAT per disc. Future replacement discs will be in the region of £270.40+VAT as they will not require the bell. This will be a far superior braking system and more suited to the modern day car.
I know Willy sells brake kits.
Turbohoses lists the front rings for $375/ea.
Looks like Raiden sells both front rings and hardware for $685.
Anyone else who sells these?
