Whats the clutch of choice these days for a bpu++?

[sublime_whatigo]

This is for a friends car with 16t's and supporting, most likely will never see a track and he is running an 18 spline so a little bit of slip is not a bad thing.

Last I heard people were avoiding the sprung hubs, so I was thinking a Spec stage 2+ unsprung? I will not buy another SB unless its a stage 5+ modified like I run so dont bother mentioning that.

Maybe an rps pp and stock disk, who sells just the pp these days?

Thanks, I just really hate shopping for clutches with my luck, and I will feel terrible if this clutch doesnt last for him.

When I got my first RPS pp I got just the pressure plate and used an OEM disc ... I forget who it was but that means someone, somewhere sells em separate. I think that'd be a solid choice, I've only ever ran RPS max pressure plates with oem discs and it's always held everything I've thrown at it.

I like my new SB stage 2 clutch with the IPS lightweight flywheel

Just don't keep up the clutch too much or you'll have a clutch swap in a parking lot on your hands :whistles:

Stock clutch will hold pretty good, if he doesnt plan to launch the car, and it will be very nice to drive that way. Otherwise a mild PP will hold a decent launch and hold a bit more power as well.

IMO, I'm running a BPU @ 15psi on 9b's and I use an Exedy OEM replacement clutch w/ an OEM flywheel. Well over 20 pulls and almost 2 years later it's still holdin strong.

ACT MB019 pressure plate and stock disc holding great for me:

Light pedal feel and excellent streetability. Ordinary people wouldn't realize it wasn't a stock clutch.

The RPS plate is great too, but about $100 more.

The stock clutch disc is holding up to 19t power for you? Wow, I guess I didn't realize how much a pressure plate does for holding power. I've got an ACT, Centerforce, and a Southbend pressure plate sitting at home, but I always figured I'd need a good performance clutch to be able to hold the extra power I'm running. A stock disc at probably $70 sounds A LOT better than $500 for a spec 2+

sure, the RPS plate rated at 580 torque uses the stock disc. The act is rated at 500. RPS or ACT may take a bit of the marcel out to make it engage a little quicker, but the material is stock.

The act and RPS plates are around 30% more clamp load (the mb019, there is another Act plate that is less), so they support 30% more torque. The stock clutch is actually pretty good, so add 30% to what it can hold and you have a decent clutch.

Certainly if you aren't going to routinely launch then a stock disc based clutch is best for streetability and longevity.

If you drive like a fiend then a 6 puck or spec stage 4+ type disc with no center springs is the way to go.

Hmm so I'd be alright to use a stock clutch with any of my pressure plates and hold 15g power all day long? Even with launches and spirited driving? I was under the impression that the stock disc was no good after about 400hp at the crank. The upgraded pressure plates must make an appreciable difference then.
