Firstly, I must apologise to Ted Rice. Just after I posted this message he got back to me with prices. However, I am pretty shocked, not so much by the brake prices, but by the prices of the lenses and wastegate diaphrams:
Front Rotors: $325.62 each
Front Brake Pads: $262.35 set
Driver's Lens: $295.00 each
Turn Signal Lens: $330.00 each
Diaphram: $85.05 each
Anyway, the discs on my 89 TT #40 are 13" diameter so they are probably as described previously. I will confirm with Ted as to whether these are Brembos or not.
Another interesting note for those who have asked in the past, we do have a Corvette Club here in South Africa
www.corvette.co.za (website is slightly out of date). We have about 100 members and many events throughout the year.
Additionally, South Africa has some pretty nice highways and our cops only have radar guns that they have to use from the side of the road, so a quick scout down one side of the highway for a few miles and then one has a straight run at whatever speed is reachable in the opposite direction.
