949 racing clutch longevity?

949 racing clutch longevity?
Just received by 949 racing twin disc.
I was reading through the instructions and it said the clutch is good for 150-200 drag passes or 20,000 street miles. This came to me as a shock seeing how I street drive 10-15k a street and dont intent to replace my clutch every 2 years.
Given that I was wondering people that have had the clutch how many miles have you gotten out of it so far?

as someone who ran both cerametallic disks and organic disks in my custom (non 949) twin plate clutch at two different times, I'd say that estimate is fairly accurate.
Tilton told me their twin plate clutch has tighter tolerances for engagement than a standard OEM style clutch because of the additional wear surfaces. Not only do you wear more surfaces at once, but you don't get to wear the disks as thin either.
Keep in mind also that mileage really depends on how you drive it. If you're not slipping the clutch, you're not wearing out the clutch as fast. If you drive in stop and go traffic, it'll die sooner. If you're on the long haul, it'll last longer.

Those generic estimates are provided by the pressure plate manufacturer. They could not make discs that met my requirements so I have my own made. They're .290 thick and will likely last you forever. Unless you loan your car to someone that likes to slip the clutch across every intersection at full throttle, I wouldn't worry about it. We have twin organics with thousands of street and track miles that still look new. We find that out when folks blow their transmissions from too much powa, unfortunately for them.

the organic disks lasted me way longer than the cerametallic. 20k with a considerable amount of that in stop and go traffic.
if you're not in traffic, get the damn twins.

What happens on the 949 clutch if the rivets break off the clutch disk, or the springs pop-out of the disc, or if the fingers break? I've dealt with all of these problems on other cars. I always get weary when I buy expensive clutches becuase I have a miserable track record with everything other than the Spec S3 which is in my car, but so heavy I can't downshift fast enough.
Seriiously though, if this clutch will last as long as my S3 (still going) and I can swap friction materials, I may go for it.

I put a twin plate clutch in my daily driver 5 years ago and ran it for 4 years. replaced disks maybe 3 times and rebuilt it once. it's due for both and out of the car now because I don't have a garage or built motor.
the organic disks lasted me way longer than the cerametallic. 20k with a considerable amount of that in stop and go traffic.

I didnt run sprung hubs so that helps. Honestly they aren't necessary, especially on onrganic disks.
I actually broke a diaphragm spring during round one of the twin plate probably from overstroking it.
but since the thing is rebuildable and you can get new disks and plates... well it's still more expensive to service than the cost of an ebay clutch but it's also baller.

Pretty hard to kill one of our clutches even if you are trying to.

Other imports using the same cover design and clamp force from the pressure plate supplier. Many drag racers are running this clutch design, albeit with much heavier flywheels but a bunch more power than most Miatas will ever make. When I hear people concerned that our twin might not stand up to their 300whp in road race conditions, I have to chuckle a bit. Not even close to this thing's limits. As I had mentioned when we first launched this product two years ago, it's overbuilt. I could build a 300whp road race clutch and flywheel that weighs about 7 lbs but it would be impossible to street drive and not last very long.
