I bought a set of used big reds which arrived today which I plan to install on my 993NB. Upon inspection, the fronts have the numbers 20.5249 and 20.5248 stamped on them. When I look up the product number for 993TT brakes I get a different number. I did a quick web search and I hear conflicting things ranging from there were also small reds to there was a difference between early year and late year big reds. Anyone know what the story is?

post a pic from the side or compare to this if you know what you are looking at
993RS/tt front


993RS rear, tt looks the same but isn't


or go by pads, from back to front in axle sets 993RS&TT front, 993RS&TT rear(which is the same as 993front), 993 rear


the difference between RS & tt rears can be seen here, tt top RS bottom

Thanks Bill, judging from the size and style of pad as well as the cross drill pattern in the rotors, I indeed do have the 993TT brakes.
