I have a dealership and received a gallardo that had replaced clutch recently (actually it was the original used clutch but remade with new materials), and it had a problem that in low speeds (0kmh-10kmh) it would behave improperly like giving it just a little acceleration would make a hard acceleration and sometimes it was so agressive the engine would die. If the car was fully stopped and I pressed the accelerator, it would just do a hard “bump” like trying to start a manual car with a gear engaged and not pressing the clutch pedal (my gallardo is egear by the way).
I had the clutch removed and remade in a local shop, when I was going to leave the workshop the clutch started slipping. They redid the job again, I left the workshop everything seemed fine, but when I arrived home the reverse wouldn’t engage. I went to the shop again, and this time when I went to get it the car was running smoothly like it should. After around 100km, the clutch started slipping again. I took it to the workshop again, now when I got the car, the clutch is “hard” again, making the aggressive bumps it did before although the engine now doesn't die (although I didn't test it enough), which makes it really hard to for example park as you give a little acceleration and the car just goes like a meter making it hard to drive in low speeds.
From my description what do you think the problem might be? Is it the clutch or another part of the clutch? Do you think buying a used clutched from ebay since it's a used car and it's for sale, and putting the used clutch it would solve the problem?
Based on your description, it looks like you have a rebuilt clutch that was not set up or calibrated correctly in the rebuilt process. One of the symptoms that you mentioned was that it wouldn't go in reverse. That's a direct result of not setting up the clearance correctly in the rebuilt process.
PIS is your engagement bite. You can try adjusting your PIS but if it was not set up correctly, PIS won't help. You can think of an engine that's been rebuild incorrectly. You can try to tune the engine but it won't work because the rebuilt was not done correctly.
We have a few different Kevlar clutch models that last 200-350% longer than a stock clutch. You can read about our happy customers at this 45 page thread.
