Dont have any experience of B/D clutches but a friend on mine fitted black diamond discs/pads to his subaru.They only lasted 16 months 7000 miles.(a load of ****e).I spent a lot less money upgrading my brakes to Brembo 166 callipers (50) brembo 305mm GTA discs (85) Brembo 166 pads (42).Two years on 24000 miles I removed the pads roughened them up checked the discs just nicely bedded in will easily be good for another 30000 miles.
My advice don't waist your money on black diamond.buy Valio

Brembo clutches ?. Black diamond do very good clutches I was looking at a stage 2 Kevlar for my Gta but went for a similar clutch from cg motorsport who I would look at too as there alot and cheaper, and they sell alot more to the diesel owners.

Quick question - did he get better mileage from other components?

I also had a friend who would go through clutches and brakes on his Subaru on a yearly basis. I raced him once and noticed in day time his discs were glowing - I get 260C on my discs by the time I get off the track after 1 cool down lap

dont bother with B/D if you want a uprated clutch go for a CG Motorsport stage 2 clutch. They are much cheaper and mine handles everything i can give it. Nice and smooth and good in traffic.

+1 , also stock valeo or sachs are supposed to be good although I think there the same.

I swapped like for like, clutch and DMF.

No one could answer the question. Even with all the mods and a huge hike in torque its more than fine.

They are terrible, stay well away!!!!

I got the Kevlar uprated one for my car and it held no more than a standard clutch before slipping! They came back to me and said it was only rated for 30% over standard engine output, not 30% uprated as per the adverts. So that would offer me 299lbft when a standard clutch can hold near 400lbft.

Don't waste your time and money, get a Sach one. The Sach clutchs have specific NM ratings and the factory tests them to 10% over that rating, so the 500NM one I am waiting to fit now WILL hold 550NM+ and people have run near 600NM on them.

just my fifty cents to kevlar clutches. They need proper bed in. Also they cannot recover from overheating a much, the surface become glassy then.

Imo kevlar is not suitable for daily use. Also Kevlar does not deliver more friction force than normal organic material.
The only advantage of Kevlar is better heat resistance, so it can have more abuse.

Thanks for all the input guys! b/d no-go do not want to go through effort of getting one and fitting it,and then it does not work.

Glad I asked!

Dont go for a stage 3 it will be almost impossible to drive in slow moving traffic jams. You will end up stalling it all the time. You need to use loads of revs and gentle use of the clutch just to set off.

Then the dual friction is a much better choice. More bity than standard or stage 1 but still applicable for daily use (and slow traffic).

Ive got a CG Motorsport stage 2 Kelvar and it drives great. Smooth light feel when and havent had any slipping from it either even when running nitrous at full chat.

Do you give it extra fuel when the nitrous is on?

Ive got a rich map on the top end so the nitrous only injects when on full throttle. Its spays in about 8" before the trottle body. It makes quite abit of diffence when its on but not really any good in 1st and 2nd gears because it wants to wheel spin all the time. Im just thinking about mounting a FMIC next month then getting it remaped again. Hoping for 220bhp when its done.

There's just something great about big red switches you need to flip to turn stuff on, it reminds me of ANY sort of missle arming .
