As a general rule for 5 speeds yes. The 6 speed ones are considered to be much better (especially 06 onwards) and are suitable for rallying.
Back in the day of 5 speed group N Subarus, no one used the DCCD with any success. They used to open up after a few kays of hard driving.

Not to mention, 6 speeds generally have an 'auto mode' or can be hooked up to similar aftermarket setups which saves being set in 'lock' mode all day long.

PS- Yes Doug, wasn't really sure what comes out with what (hence the question mark in the poll).

Anyone have any super handling probs with the 20Kg on tarmac. Stace, someone mentioned you once ran one in one of your vehicles...??

So will running an aftermarket controller which has an auto mode help save it a little?

glad i read this! mine seemed to be coping well with 310 hp atw, better get mms to pull all the DCCD gear out when we swap the box and put a cusco 35/65 tarmac diff in there, i'd rather sell one in working condition than break it and have nothing to show for it

ive had 4kg/12kg and plenty of DCCD centres. (all my current gearboxes have dccd, and i pack spares!)

i dont do any circuit work (maybe once in a blue moon), only rarely do drags.

basically the heavier the diff, the better the handling, a DCCD at full lock is equivelent to a 20kg centre (run full lock at the drags).

although, if you work the DCCD centre hard, they loosen up and eventually suffer eternal rear bias only, which in my opinion- effectively the same as leaving the diff unpowered, and near the same torque split as one of those cusco centres.

possum bourne motorsport were at one stage offering rewinds on 5 speed centres.

to be honest, dccd for me is about having fun. i'm a hoon at heart, so i just like turning tires. if you want to be fast on the track, i'd be opting for a 20kg, and relinquishing the car from daily duties.

just leave the diff un powered.

5 speeds will break no matter what centre is in there.

i wont be keeping the RA 5 speed in there, im surprised that lasted as long as it did...was more thinking of selling the whole lot i.e front diff, centre diff all the DCCD gear and gearbox. A few people showed interest when i initially popped the motor and was going to part it out completely and start a fresh in a few years time.

I've never tried a Cusco 35/65 but I reckon it's too much rear. I drove a R32 GT-R once that had lots of power ~ 450 horse, it wasn't fast on the skid pan as there wasn't enough going to the fronts and too much to the rears. I felt unbalanced, nervous and less fun than a 200 horse Subaru after you get tired of smoking them as you spin it backwards. I'm thinking 300 horse and 65% rear drive in a GC8 you better have sticky tyres and 2+ cans of Red Bull before you get behind the wheel.
