We are faced with the need to install a new clutch (after 122k mls, we installed a new OEM clutch, flywheel, rear main seal; now clutch is slipping).

The car has some mild modifications:
- Carbonio Cold Air Intake system
- APR inlet tubes for intake and turbo
- TAP 50HP chip
- Cat Back, Milteck exhaust

New modification: installation of test pipe (installed yesterday)

Engine horsepower could be (Manufacturer claim): 218 HP (12.5 lbs boost), 210 ft*lbs (+50hp/+52 ft lbs increase).

We have looked into the following (see below). What are the forums recommendations for our purpose? Goal: smooth engagement, longevity, strong enough to handle the mods above.



Southbend:

Street Series
The Street Series kits are intended for cars that are mainly driven on the street and occasionally at the track. All Street Series clutch kits are designed with full face clutch linings bonded to a Marcel type disc to give you a smoother engagement than any puck style clutch. Full face clutches are available with the same friction materials as the puck style clutches and will not sacrifice torque.

Rally Series: HD Stage 1: Torque Capacity 220 lb*ft: Rally kits contain a modified high performance pressure plate and heavy duty organic disc. The linings on this disc are premium woven medium metal content lining. This facing has a 9000 RPM burst and dissipates heat quicker than any other organic lining on the market. This kit generates 1/3 more torque then stock. Also included in the kit are a throw-out bearing, pilot bearing, and alignment tool.
TX Series: HD Stage 2: Torque Capacity 290 lb*ft: TZ kits contain a modified high performance pressure plate with a heavy duty KevlarŽ lined disc. The metal backed KevlarŽ linings provide a smooth engagement and have the torque capacity to handle high horse power, high revving engines; the disk is rated to 12,000rpm. These clutch kits maintain a stock feel at the pedal and have unmatched durability. Also included in the kit are a throw out bearing, pilot bearing, and alignment tool.
OFE HD Stage 3: Torque Capacity 300 lb*ft: A Feramic full face lining on the flywheel side and a "Medium Metal" content Organic lining on the pressure plate side. This combination runs cooler and significantly extends clutch life. The OFE series clutch not only engages very smooth, it has the torque capacity of other Stage 4 clutch kits.

Spec Clutch:

Stage 1: 275 lb*ft
Types of Driving:
Street, Drag, Drift, Road Race, Rallye, Pulling, Autocross
Features an integrally molded carbon kevlar-based, high performance organic lining that offers smooth engagement and excellent life. This lining has an integrally bonded steel backing for strength under high clamp loads and temperatures. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Best for street and many track/off-road applications.

High clamp pressure plate
Steel-backed and multi-compound woven organic material
High torque sprung hub and disc assembly (application dependent)
Bearing and tool kit (application dependent)


Stage 2: 330 lb*Ft
Types of Driving:
Street, Drag, Pulling, Autocross
Features segmented or full faced pure Kevlar disc with steel backing. This lining features excellent drivability like the stage 1, but offers slightly longer life and higher torque capacity. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Best for street, drag, pulling and autocross.

High clamp pressure plate
Pure Kevlar friction material
High torque sprung hub and disc assembly (application dependent)
Bearing and tool kit (application dependent)

Clutch Masters Stage 1 Clutch:

This assembly is designed to provide extended life and superior holding power for cars with moderate power upgrades and/or more enthusiastic driving in abusive conditions. The pressure plate offers 40-65% more clamping force than a stock cover. Most organic discs provided in our assemblies include steel-backed lining to enhance the structural integrity of the material which is complemented by the highest quality hub assemblies available to ensure durability and driveability.

Stage 1 Clutch Masters Clutch Features:
-High performance street system
-Holding capacity 70% over stock
-Heavy-Duty reinforced pressure plate
-Hi-Leverage pressure ring design
-Sprung hub/cushioned disc
-Steel backed organic friction material

All Clutch Masters systems come complete with:
-Pressure Plate
-Clutch Disc
-Throw-out Bearing (when applicable)
-Pilot Bearing or Bushing (when applicable)
