Reinforced clutch with copper disc, use and durability

Many of you order reinforced clutch kits from us, both single-disc and double-disc with the use of clutch discs with copper plates. Many of you know what they are buying but others of you, especially for non-experts, don't know and ask us how much the durability of a clutch reinforced with copper disc.

It is easy to understand that the duration can depend on many factors, including:

1. the driving style and the type of route where the car is used, speed track, mountain, road, etc.
2. the type of transmission whether 2-wheel drive or 4-wheel drive
3. the gear ratio, with close or original long ratios
4. the size of the clutch originally, such as the diameter and width of the pressure plate and disc sector
5. the state of wear of the flywheel and the correct "pull"
6. the size and type of rims and tires
7. the torque and consequently the power to sustain
8. the most important factor remains the type of clutch in place which is managed based on the load of the pressure plate used, original reinforced type or Racing type machined from solid billet.

Generally speaking, a copper clutch is considered a racing clutch , in our opinion not recommended for road use with long distances, but necessary in some cases as it has The copper disc has the advantage of being more resistant to high temperatures and have a greater torque transmission capacity and therefore a greater friction coefficient, but has the disadvantage of lasting much less, being noisier and more grumpy to drive, even if the latter can be improved based on the compound of the petals , on the number and size of the plates or also on the basis of the possible progressiveness of the clutch disc and on how the disc and the shock absorber battery were constructed.

We can state that the "average duration" can depend on many factors such as the driving style and the type of route where the car is used, but for racing cars the maximum duration is between 3 and 5 thousand kilometers maximum, while with an Using the car in competition as a track or track day can even last twice as long, around 10 thousand kilometres.

In any case, in our experience we have never seen a reinforced clutch kit with a single copper disc for "quiet" uses last over 15-18 thousand kilometers when well used, while for a reinforced clutch kit with a double disc the duration is certainly much higher .

At the end of the clutch, in addition to finding the defect of the clutch which will slip primarily especially on high gears with the engine at low revs, 4th and 5th gear and also changing gear at high revs at speed will be more difficult.

Premature slipping of the clutch could also depend on external elements that can affect friction, such as oil on the surfaces of the disc or flywheel, for example due to the failure of a flywheel or gearbox side oil seal or the failure of a hydraulic bearing , in this case it will be necessary to replace the entire disc and carefully degrease the entire inside of the gearbox together with the flywheel and pressure plate.
