Looking for help with a clutch question(s)

[FMGT1999]

I need some advice for a good friend of mine. He is having clutch problems. Slipping and making noise. I run an AODE 4R70W, so I am coming here to get him some help and get his questions some answers.

He has the following clutch:

Summit Racing Part Number: CTF-DF161057
UPC: 788442016574

Input Spline Quantity: 26

Input Shaft Diameter: 1.125 in.

Disc Diameter (in): 10.400 in.

Disc Diameter (mm): 264mm

Disc Material: Organic/Carbon composite

Disc Style: Sprung hub

Pressure Plate Style

Diaphragm

Throwout Bearing Included: No

Alignment Tool Included: No

Pilot Bushing Included: No

Flywheel Included: No

Counterweight Assist: Yes

Mounting Hardware Included: No

He think it is ok, but his driving killed the clutch after 20 pass. He is unsure of a couple of things maybe you all might know the answers,

1) He currently has a 10.400 disc diameter, will a 10.500 work OK?

2) Is a "twin disc" better than dual friction?

3)The adjustable clutch quadrant.. does that adjust the actual clutch or just adjust the pedal feel?

4) Dose anyone recommend a certain clutch?

Thanks,
Kyle

PS: if you need any more information please post it here and I will follow up with him to get the answers.

Bump,

Come on guys someone should be able to help me on this one, it's not that hard of a question!

Maybe he should think about running a ceramic disc of some kind that's what my buddy runs in his turbo car they are hard on flywheels but they take alot of abuse or go with a center force dual friction clutch but they also chew up stock flywheels pretty quick

If he is running a centerforce df clutch they do tend to blow apart very easy .
