Your clutch is fucked and so are your engine mounts.

Besides, 60kmh in 4th isn't lower end, 40kmh would be. And the engine still shouldn't rumble there.

>>13960559
Your engine lacks torque because the rpm is so low in a high gear at a low speed. Instead of doing 40 in fourth, do it in third or second.

Do they need to be replaced or repaired?

>>13960583
depends on the gearing bro, my car is sitting at about 2krpm at 40 kmh in 4th

>>13960731
How do you expect to repair cracked/hardened rubber bits?

>>13960968
I meant the clutch, I dunno why I said do they instead of does it

>>13960583
Not OP but I shift to 4th doing 60kmh and keep driving at around 2k RPM and in general I drive at low RPM with shifts at 2.5k RPM at most, am I risking to fuck the car up this way? Car is Audi 80 1991

No, a clutch is a wear item. You can't fix it. you need to buy a new one. What you suggested is exactly like adding material to a brake pad instead of just buying a new set.

>am I risking to fuck the car up this way?
No. Higher gear + lower RPM is the preferred combination (where applicable) for normal driving.

>>13961187
Is there any threshold like below this RPM something might go wrong?

>>13961366
>something might go wrong
With low enough RPM you'll stall. If you know how to drive, you'll feel it's time to shift into a lower gear well before that happens. To answer your question... No.

Yeah I know how to drive stick, I actually know less about driving auto than stick (Yurop), I was just wondering if there's any consequences of low RPM driving like clutch wear or something. Thanks.

Sorry. My bad.
>consequences of low RPM driving
There are consequences. Lower fuel consumption and lower engine and transmission wear and tear.
