What does the device consist of?
The purpose of thresholds, popularly boxes, as a composite load-bearing element of the body is to prevent torsional deformation in the middle part. Severe destruction of the boxes is fraught with irreversible loss of geometry - the body begins to “walk”. The nine has a lightweight and simplified body. Therefore, even a spar that miraculously did not have time to rot will not save the situation. The car's steering becomes unpredictable. The structure of the structure is quite simple. The main load during movement is taken by amplifiers (two on each side - large and small), welded to the outer part of the box structure. The amplifiers are welded to the A-pillar, B-pillar and floor. Additional structural rigidity is provided by connectors that are welded to the bottom.
Dimensions
Factory thresholds on the VAZ 2109 are supplied with a 1 mm thick reinforcement. Only 0.8 mm samples are available for sale. Despite its flimsy appearance compared to the factory model, such an amplifier is quite acceptable for providing the required rigidity. Especially taking into account the remaining service life of the VAZ 2109.
Also, on all new VAZ body parts, the size may differ from the factory one, so in most cases the part needs to be adjusted at the installation site.
Are there any differences between the thresholds of VAZ 2109, 21099 and 2108
Thresholds, amplifiers and connectors from VAZ 2109/2109/21099 to 2115 are completely identical. Since the 2108 body is a two-door version of the nine, the dimensions of the component boxes are slightly different. In turn, all elements of the VAZ 2108 threshold are compatible with the coupe of later years of production - 2113. In terms of workmanship, front-wheel drive Samaras of later years of production are more susceptible to corrosion. According to reviews from owners, a systematic deterioration in the quality of bodies began in the 1990s.
