What clutch should I get for my [DSM]?


This varies wildly. Ask on the forums for assitance in choosing the right clutch for your setup.

Southbend is very popular with ACT Streetlite flywheel. Southbend use Exedy OE Hub and replace the material with their own. RTM Racing has provided some upgrade info for the clutch kits.

Stage 1: 
A beefed up version of the stock clutch with more clamping force and a sprung full-face friction disc. This clutch is recommended for a daily driver with stock or near stock power. Pedal pressure similar to stock. Torque rating 300 ft/lbs. 

Stage 2 Daily: 
Comes with a heavy-duty pressure plate with increased clamping force over stock. Friction disc is an organic disc with a high metal content that increases the co-efficient of friction to twice that of the stock disc. Pedal pressure similar to stock. Recommended for a daily driver that sees occasional track use. Torque rating 320 ft/lbs. (For comparison, this clutch would have similar performance to an ACT 2100 w/street disc.) 

Stage 2 Endurance: 
Comes with a heavy-duty pressure plate with increased clamping force over stock and with the fulcrum slightly altered for positive disengagement and quick shifts. The friction disc is of a hybrid design: full-face feramic (sintered iron) lining on the flywheel side and high metal content organic lining on the pressure plate side. Engagement is positive yet buffered due to the high graphite content unique to feramic facings. Pedal pressure similar to stock. Recommended for a daily driver that sees occasional drag use but with emphasis on rally or endurance racing. Torque rating 415 ft/lbs. (For comparison, this clutch would have performance characteristics somewhere between an ACT 2100 & 2600 with a lighter pedal.) 

Stage 2 Drag: 
Comes with a heavy-duty pressure plate with increased clamping force over stock and modified for a puck-style disc. The friction disc is of a 6-puck design which reduces rotational mass while increasing pressure on the surface of the friction material. Additionally, there is no cushion material between friction linings which helps keep clutch pedal travel short and quick. The friction material is graphite-impregnated ceramic. This compound exceeded all other friction materials when tested for durability, reduced chatter, heat transfer and torque capability. Pedal pressure slightly more than stock. While this clutch CAN be used on a street machine, it is designed and is generally recommended for drag racing. Torque rating 465 ft/lbs. (For comparison, this clutch would have similar performance to an ACT 2600 w/6-puck disc with a lighter pedal.) 

Stage 3 Daily: 
Comes with a heavy-duty pressure plate with significantly increased clamping force over stock. Friction disc is an organic disc with a high metal content that increases the co-efficient of friction to twice that of the stock disc. Pedal pressure about 25% stiffer than stock. Recommended for a daily driver that sees occasional track use. Torque rating 400 ft/lbs. (For comparison, this clutch would have similar performance to an ACT 2600 w/street disc with a lighter pedal.) 

Stage 3 Endurance: 
Comes with a heavy-duty pressure plate with significantly increased clamping force over stock and with the fulcrum slightly altered for positive disengagement and quick shifts. Friction disc is designed for the special needs of a vehicle with circuit racing in mind. Kevlar friction material is used for its unique static-to-dynamic co-efficient ratio at high energy levels which translates to a perfect transition from one gear to the next. Pedal pressure about 25% stiffer than stock. While this clutch CAN be used for spirited daily driving and occasional drag use, it is designed and is generally recommended for rally, endurance racing, clubsport and autocross. Torque rating 450 ft/lbs. (For comparison, this clutch would have similar performance to an ACT 2600 with a lighter pedal.) 

Stage 3 Drag: 
Comes with a heavy-duty pressure plate with significantly increased clamping force over stock and modified for a puck-style disc. The friction disc is of a 6-puck design which reduces rotational mass while increasing pressure on the surface of the friction material. Additionally, there is no cushion material between friction linings which helps keep clutch pedal travel short and quick. The friction material is graphite-impregnated ceramic. This compound exceeded all other friction materials when tested for durability, reduced chatter, heat transfer and torque capability. Pedal pressure about 25% stiffer than stock. While this clutch CAN be used on a street machine, it is designed and is generally recommended for drag racing. Torque rating 525 ft/lbs. (For comparison, this clutch would have similar performance to an ACT 2900 w/6-puck disc with a lighter pedal.)
