Hi Ralph not disputing yoursource but mine say differently
Currency conversion is at today15-05-2020
My source is actual quoted prices publishedopen source I do not make this stuff up but quote if from actual informationI have sourced from a reputable third party supplier .
Recommended FRONT WHEELS price for a pista is 9375.34( each) pound sterling discount price is 7141.17(each) pound sterling x 2 is 14248.34 pound sterling they will only sell them in sets of Front driver Front passenger so converting them to USD totals 17438.40 USD for the front wheels (2)
Going through the same exercise forthe REAR WHEELS recommended price is 9628.80 ( each ) pound sterling discount price is 7333.88 x 2 Rear driver Rear passenger is 14667.76 poundsterling they will only sell them in sets of 2 soconverting them to USD is 17908.99 for the rear wheels (2)
So the total best price you could getthem for is 35347.38 USD Discount price non Ferrari but still newcarbon fibre wheels and that excludes any freight fitting etc .
Using the recommended retail price Iassume this is what Ferrari would charge clients is
FRONT WHEEL RRP 9375.84 each x 2 is18751 .68 pound sterling and converting this to USD is 22888.26 (2)Front Driver front passenger
REAR WHEEL RRP 9628.80 each x 2 is19257.60 pound sterling and converting them to USD is 23496.87 (2)Rear driver rear passenger
So the total price based on recommendedretail price is 46385.13 USD that makes them approx 71870 .37 AUD based on a currency conversion rate of 0.65 AUD cf USD
