What clutch are you guys using with your 207's?
I have Ver.8 207 tuned by Mikey to 19psi, full 3" catless exhaust incl. bell mouth dp, spearco 1000cfm top mount, HKS short ram, walbro upgraded pump etc. Not sure of the power level but it is slipping the brand new Exedy OEM replacement clutch I just put in after about 8k miles.... I still have to stock 5-speed so I have to weigh clamping force with protecting the transmission. Thanks for your input/ suggestions. |

exedy Stage 1 clutch and new flywheel would be more then enough. Confused as to why the OEM is slipping. Maybe it has oil leaking from the main seal? Someone resurfaced or reused the old flywheel? Or maybe driver error/damage from racing or abuse? Need to pull it apart and look.

I second Clark's input. Given those modifications an OEM unit should last a long time. As for an upgraded option, check out the reviews on Southbend clutches. Their Stage 1 or even Stage 2 full face organic would do nicely. The OFE would be a bit overkill in there.

Good advice. I like a standard full face clutch for a 5mt trans. Kind of a buffer. I would rather have the clutch slip a bit and cushion the stress to the trans.

Stephen...whats your take on the pedal pressure of a Southbend stage 1 clutch compared to a exedy stage1? comparable or would i be doing leg presses on the Southbend?
Been running this exedy stg 1 on the 6sp, feels perfect |

Pedal pressure comparisons from past installs:
5MT southbend stage 1 = same as stock southbend stage 2 = slightly heavier than stock, but no where as heavy as Exedy stg 1 pressure 6MT southbend stg 2 = = feels the same as stock, and probably close to the exedy stg 1 southbend stg 2 OFE = Same effort at above since they use the same pressure plates. |

Wrick - looks like we only have a low 256K 800*500 version. You are more than welcome to it. Simply email me at [email protected] and I'll get it sent over.

Thanks guys for the quick response. The flywheel is an act streetlite and was all new install with the motor. I'm not noticing any oil burn/loss or smelling oil burn so I don't think it could be oil leak but anything is possible. I got 130k on the OEM clutch with the "stg 4" ej205, obv. Diff motor/ torque etc but should point to driving style ie not tearing up clutches. Could it be a bad/ defective clutch in terms of wear surface? The symptom is when applying throttle, the Rpm's advance but the car does not. Oddly, not necessarily in synch with where I perceive the most torque to be generated but I could be wrong. Thanks for your input! Having this motor and not being able to enjoy it is unpleasant.

Hmm, new flywheel with the new clutch. Did it have a bit of shudder when engaging from a stand still? We've seen instances where the driver rides the clutch a bit longer to avoid the shudder. This driving style will shorten the life span. If the clutch engaged smooth, then I'd suggest jumping brands to see if that helps.
Clark mentioned a leak on the rear of the motor, which is exactly what happened to my own motor. 100% new short block from Subaru leaked out of the wrist pin access panel, which then got on the flywheel and eventually the disc. Stephen |

Same engine Same trans Same clutch Stock, original flywheel Works great for me. How much torque are you putting out? I'm at 287wtq on EFI's dyno. |

It could be the center or rear diff slipping. One of my axles popped out causing slip once.
I'm running a competition stage 3 clutch and I love it. My cars a daily too. It grabs hard and launches hard. It's a little less street able than my act hd organic clutch was but I'm not complaining. It will take abuse. |

Stephen, no shudder from standstill so don't think I burned it up that way. Also, if your getting oil on the flywheel, won't it shudder? My old LandCruiser has a leak at the rear main and it shutters because of the inconsistent friction surface.
I'm not sure what tq numbers I'm putting down as we road tuned it. I had the tech check to see if an axle had popped but he reported they looked fine..... Is there any difference in feel between an axle popped out and a slipping clutch? Thanks again. |

My car would slip when first pulling out. I thought it was my clutch so I was easy on it otherwise

My exedy oem spun twice on a wot run on a flat road in 4th and 5th gear. I'd been testing a kinugawa waste gate actuator, boost build was super fast, cause the clutch to spin. I let off the gas quickly in both instances. I'm back to running the stock waste gate actuator and taking it easy on the clutch. I'd been looking into the south bend clutches, I'll probably give them a try.

My OEM 5 speed clutch with resurfaced Sti 5 speed lightweight flywheel slips sometimes in the high gears, depending on load, at 340 Wftlb.
It is a needed protection for my 5 speed, I think. I think the OEM pressure plate clamping force for 5 speed is 10-15% less than the 6 speed. I'm thinking that since the actuation mechanism is the same, this must translate in the pedal effort feeling directly. So probably a clutch pedal that engages a 6 speed clutch feels 10% heavier than one that engages a 5 speed. In terms of Sti performance parts, the "stage1" Sti performance pressure plate for 5 speed is slightly over the OEM 6 speed pressure plate clamping force, less than 10% I think. From a 6 speed it would not be noticeable, but from a 5 speed switching to that, you would probably notice it. I think that the whole clutch assembly for a 5 speed with high clamping force, say like a Sti lightweight flywheel with disc and plate may be either lighter or have the weight distributed on a smaller diameter than the 6 speed OEM unit and therefore provide an advantage. So, when I go 6 speed I may stick with a 5 speed clutch, with uprated pressure plate and maybe a stage one full disc. |

Would the crawford solution be more acceptable ? ( not considering the price )

despite the price, the crawford one works. Its baffled and heated to prevent the oil sludge during cold weather. The key to picking a good can IMO, is the baffling to condense the oil vapor as much as possible. The heated feature of the crawford is an added bonus. The perrin unit is comparable in design to what i've seen, with coolant routed in to heat up the oil as well.
