I have one of the SS700 Transmissions from Keisler well the clutch is starting to slip, i should have replaced that clutch that came in the keisler box for a decent brand name as this clutch had no name except for made in mexico.
so i was wondering what you guys recommend as for a nice road race / autoX clutch

Center force dual friction has worked well for me

I recently got a RAM 11" Powergrip clutch that is rated for 550 TQ and the drivability is excellent.

when would one use the twin disc system? is that for tons of torque?

There are some different disc material options for twin disc clutches that you can use them on lower torque engines as well, but mainly the idea is that the higher the torque the more surface area you need for gripping power. The nice thing is that with a car that say has 600ft/lbs of torque but sees only street duty you can get a twin disc system with an organic disc kit that will give you very good engagement characteristics and still hold up to that level of torque that you wouldn't be able to do with a single disc clutch with an all organic disc.

Something to add to Craig's post..........rear tires also play an important part with a clutch selection. General rule; the stickier the rear tires, the more aggressive clutch disc you will need for longevity.

We offer McLeod Racing Products and the most common clutches we use for the LGT700 are the single disc 75XXX series or the twin disc 69XX-XX series.

The McLeod 75XXX series single disc pressure plate has a 2400lb static pressure plate, this is very close to a stock clutch pedal feel.

Street Extreme - 700HP at the crank - puck disc - street tires, drag radials, sticky tires
Super Street Pro - 550HP at the crank - organic/puck disc - street tires only
Street Pro - 400HP at the crank - organic disc - street tires only
Street Level - 300HP at the crank - organic disc - street tires only

The McLeod 69XX-XX series twin disc pressure plate has a 1900lb static pressure plate and will give your mechanical TOB setup a hydraulic TOB clutch pedal feel. Running a hydraulic TOB setup already, the twin disc will have less stress on your hydraulic TOB system.

RXT Twin 1000HP at the crank - puck disc - street tires, drag radials, sticky tires
RST Twin 800HP at the crank - organic disc - street tires only

I just upgraded from the Ram 550 Powergrip to a Mcleod Street Extreme and so far I'm very happy with the upgrade. The Ram lasted me about a year before it started to slip when hot. The Mcleod Street Extreme is just a bit more chattery on low RPM starts but other than that is very street drivable and has held up to 2 autocrosses and two full hard track days without a hiccup behind a 525 ft lb 383.
