Have just bought a pair of Sabelt 4 point harnesses ( Demon Tweeks - Caterham specific) to replace my 23 year old Caterham belts (road use only)
The belts seem to be incredibly difficult to adjust, requiring a huge amount of force to tighten them, and lots of difficulty in releasing the shoulder straps. The lap belts are virtually impossible to tighten once I am in the car, and I find that I have to tighten them, get in the car to test them and keep on hopping in and out until they fit.
I am hoping that they loosen with use; I wonder if anyone has met the same problem and if there is an easy fix to solve the problem?
