What are the differences between the '75 and '78 308 GT4 Brake System? I've been reading some of the article's I've found, and something struck in the Road and Track article ('78 I believe): "We were not especially impressed with the Dino's brakes in our 1975 test and we're gratified to find that stopping distances from 60 and 80 mph in our simulated panic stops have been reduced significantly: 167 ft (previously 208) from 60 mph and 270 (versus 316 ft) from 80." I have both articles here... The '75 car test weight was 3500 lbs and ran Michelin XWX 205x70VR15. The '78 car test weight was 3585 lbs and ran the same tires. What did they change to improve the braking ability over those few years? I do not have a Ferrari part number reference. Brembo seems to sell the only two different rotors for all 308 series cars: 277mm x 20mm, and 272mm x 22mm, but their site does not specify which years or location the rotors match up to. Thanks for everyone's continued help - Chris
Hi Chris, I was not aware that there was a difference between the years. I'd be interested to know for sure. Perhaps this thread should be moved to the Tech section? Dom
Hay Dom, I just re-posted this to the Tech section (I thought that was for more general questions, but I'm still learning the forum). Thanks - Chris
