They may have poorly adjusted the height of the cams of the plate since the steering wheel is flat and if they were left too high it is not enough to give the entire adjustment rod, the original height is 39 mm, from the tip of the cam To the club's hub. The other possibility is that you have put the disc upside down, check this with the clutch pedal depressed, putting a change and start, if the car comes out jerking without releasing the pedal, you have the disc inverted, otherwise you will have to lower the box and give the height with a caliber to the cams.
