Sprung vs un sprung.

[darrenjlobb]

My experience,

Firstly, using all of us as comparisons is flawed, as CG have changed the design of these units many times in the last few years, so its not really a fair comparison like for like.

Sprung / unsprung, in theory sprung, but in reality, I would choose the un sprung unit every time. These are CHEAP clutchs, there are made of CHEAP material and to a fairly low quality, therefore the simpler the design, the less likely you are to have issues, and on the unsprung unit, there is very little to go wrong.

The problem I seem to have encountered on recent units, is they have narrowed up on the spline in the center, which has left IMO an un satisfactory amount of engagement, This, over time, is causing the "rattle" people are experiencing on idle in neutral, as the friction disk vibrates / moves around on the input shaft, this if left to wear enough, will eventually strip the splines out the disk and loose drive, although I have given them fair abuse / I think they will fail for other reasons before this, but either way, needs sorting really, and I am actually in contact with CG regarding it at the moment.

Overall for what they cost, they do a good job, and I would just buy the un-sprung 4 paddle unit, either there kit, or just the disk and use with a brand new valeo pressure plate.
