I think (I know that's unusual) that one these guys in the front followed by two CV's is just about the complete answer for these driveshafts other than carbon fibre and/or torque tubes.
When I have some spare time, I just might look into doing this conversion to my road car. Watch this space...
Hello,I m new to your forum.My car is the Alfa 75 turbo 1,8 with gt35,I just finished my project and the car is going to produse more than 500ps.
My clutch assably is not a stock one!The only problem I have is with the rubber propshaft (mount) it brakes all the time!Please let me know about any advice or solutions you may give me.
PS...Does anyone knows were can I get a really strong rubber propshaft doughnut like the photo from MD??
Interesting power level, how will you keep the gearbox from breaking?
I actually just finished my first design proposal för the front CVJ-adapter, A bit on the heavy side but easy to manufacture.

Very nice,but where I can find something like this?(site or dealer)

Even if you build a rock-solid prop.shaft your gears will turn into a metallic soup. What gearbox are you planning to use?
By the look of your adapter plus the CV joints I bet it would take just a little weight shaved from the flywheel to maintain the stock rotational inertia. If you wanted to reduce the rotational inertia you would end up needing to go with the aluminum flywheel and clutch flywheel(if anyone makes one)
Maybe a wash for performance(on a street car), but a boon for reliability(on a race car). Also a solution to the waning supply of rubber biscuts(on any car).
My flywheel is lightened 3Kg (or ~38%). Looking at inertia; the weight taken off is at the very edge of the flywheel so the radius is large, the weight added (calculated the adapter to 1374g) is in the very center of the flywheel and therefore does not add any significant amount of inertia.
But yes, the CV joint solution is a quite heavy solution in terms of total mass, at least this disc type.

No, that is not in line with my "I love my feet" strategy.
If they were possible to make out of alu they would be on all cars, the weight saving trends of today are quite insane (in a good way) but the flanges are still steel.

I had the rubber blow apart with 150 kmh in a giulia, i can tell that is not something you like to happen, the hole tunnel area was one big hole, the drive shaft came within one cm off my leg and if metal is torn up that easy think what it will do with flesh, broke the gear box and of course the drive shaft.
and the little weight you save will not weight up for your own safety.
even the IMSA gearbox will have a problem handling that...
