Coming from the Honda world and seeing what you guys can do to improve trans...I would have thought you'd already be in the EVO side of things years ago. Thankfully, you've taken the time to consider doing the EVOs....
The perfect example is the Honda S2000 the AP1 (first few years) used brass syncros and had a lot of shifting issues. This is a factory car that revs very high (9000rpm redline) and the way Honda solved that problem was not only replacing the brass syncros with carbon but also todeveloped the AP2 (later years) with carbon syncros since it worked so well. My buddy takes his AP2 in the canyons all the time NEVER changes his oil (I try to remind him) and takes it to 8000rpm (redline) and it still shifts like butter. Carbon works point blank. He has 90k on the clock now all original tranny (upgraded act cluctch)
We had a small engineering glitch on the 1-2 synchros. The inner synchro body is too thin to support the carbon composite but we resolved the problem by redesigning the inner synchro with a steel body rather than brass.
Currently we are still waiting for revised tooling quotes. (This phase is a long and slow process - sorry)
I will post another update as soon as I have more information.
