Sorry for not posting this information in my original post, but I just wanted to make certain of a few details first.
The cost of the kit will be £810 +VAT. This represents a saving of approximately £400 on the full retail price of this particular kit. The more people that are interested in taking part, the stronger position we are in for getting a lower price.
Red Dot offer a fitting service for these calipers which comes to £117.50.
The kit would include 2 x 320x28mm discs, 2 x 4 pot Brembo calipers, 2 x brake hoses and mounts for the calipers.
In order for these to fit the Mini, 17" rims are required. Some third party rims will provide sufficient clearance for the larger calipers, however some (including the Mini S Spoke rims) will require the use of spacers to provide clearance. Red Dot offer a kit that will minimise the size of spacer required. They have forwarded me a copy of the fitting instructions and I will pass it on to anyone that is interested.
I understand that this is a reasonably expensive upgrade, however big brakes are defintely worth the expense. The advantage that they offer in improved stopping distance is easily worth around 40BHP as they allow you to brake later and harder.
Anyone interested post in here and once I have a list of numbers I will get back in touch and see if I can get a bit more money off the total cost.
Hope this is of help.
