Autozone is less expensive, at least it was for me recently:

Calipers: $25.00 USD each. (remanufactured, lifetime warranty)
Rotors: $24.00 USD each, (very fine machining, Made in China, lifetime warranty),
Rack & Pinion unit: $63.00 USD (remanufactured, lifetime warranty).

I think the problem is the cost of shipping to Europe from USA, I have shipped Jaguar parts to friends in England, Germany, and Spain, and the cost is ridiculous by US Mail or UPS. Having said that, I sold and shipped a guitar to a collector in Norway via UPS and the shipping and insurance was $225.00, not bad for the size and weight of the package. Regardless of the costs of shipping, another big problem is that each country imposes Import Duties (taxes) on the merchandise when it arrives at its destination. Everybody wants a piece of the cake.
