Carbon-Carbon 

Perhaps that could use a little more explanation, then. Carbon brakes  are carbon on carbon, in that the material is used as both brake pad and disc. However, the material used is a carbon-carbon composite: carbon fibres set in a carbon matrix (see Reinforced carbon-carbon for more technical stuff). It could actually be either reason I suppose, but they are normally referred to as 'carbon-carbon'. The topic is discussed in greater detail further down the article - I've put a '(see below)' at the first appearance of 'carbon-carbon' which links to the 'Technical innovation' section further down.

Thanks for all the further edits - I've only reverted one (sorry! -)). The direct quote from Michael Scarlett about the MRD/merde connection shouldn't be corrected (ellipsis is acceptable), even if wrong grammatically, since that's what he wrote. Unless I've misquoted of course, which I'll check when I can get my hands on the article.

One question - I don't understand why in "He also became the first man to win a Formula One race in a car bearing his own name..." 'race' is now in italics. 'Race' as opposed to what?

Also - are you sure about removing non-breaking spaces for units? My recollection is that they are recommended.

Thanks again for spending so much time going through the article  - it really helps to have someone else go through. I'm rather to close to spot some of the errors, or to act as a reader fresh to the topic. Cheers.
