Not sure these are what he's using, but heres what i'm using and a screenshot of them - afaik these are the only discs where the holes are actually see-through (alpha channel ftw!)
yup like jakg said, pick brake discs that have the alpha channel transparency thing on it so there isnt a huge black square in there and the discs are proper round with even see thru cross drilled holes!
List of brembo calipers in different colours, you might find a caliper of a different colour to the rims more effective, I prefer it anyway up to you theres plenty to choose from http://www.lfs-database.com/in ... id=2&p13_sectionid=16
No offence, but the pictures showing the difference are really, really, REALLY bad - they're way to dark, which is the reason why i posted the pictures of the ones i'm using, even if you can't actually see the caliper in mine (which you can in yours)
Of course you've gotta remember that the brake discs in LFS don't move (unfortunately) so although mine look great in screenshots, the LFS ones are "blurred" to make this look more real while racing (although if you can see the brake discs while racing your doing it wrong).
