Well you have to look at the demographic of the people that will be purchasing the kit. You are doing a rear end swap on a 86, you may want that cf driveshaft too. Im sure they will have a transmission solution soon enough. Seems to be pretty hefty thus far.

The R154 does seem to be the most likely and cost-efficient transmission alternative if one is putting out massive HP and torque through a boosted application.

The standard kit will have the Aluminum shaft, This was a gift to them for building the kit.

The CF shaft is already available; it's the aluminum one that's not been available yet.

Forgive me if I'm mistaken, but if they are including an aluminum driveshaft with the kit, I would assume that it is necessary to change the stock driveshaft because the lengths are different. Therefore, wouldn't a separate CF driveshaft need to be made as well?

Ah I see what you're saying now, ignore what I said. Not enough coffee yet haha.

It would best to call LJ at Full blown to ask the questions. We are making parts for them. He told me the kit he wants to sell with the Aluminum shaft but of coarse a carbon can also be used. he will have to give you pricing.

FullBlown · 05-22-2013, 09:30 PM

Thanks for the sick driveshaft Frank.

I will have a total packaged price very soon.

EZWood · 05-23-2013, 12:08 AM

Is there room for brakes located on the diff to reduce unsprung weight?

FullBlown · 05-23-2013, 11:56 AM

There is not much room left under there.

FullBlown · 05-31-2013, 03:13 PM

In and ready to go...
