The reinforcement of the mounting of the rear rocker arms of the BMW E46 was designed by RS-Ultimate, so that they are precisely matched to the original fastenings and grooves of the floor.

The stiffeners can be welded in without any additional alterations to the floor or the rockers themselves. The reinforcements have many additional folds which are bent in different planes on the left and right sides of the fixing reinforcement to achieve the maximum possible reinforcement of the floor.

The stiffeners have 3 additional sheets of metal on the inside of the reinforcement to be “sealed” on the semicircular side of the original groove in the floor. After dabbing, the leaves fit perfectly into the semicircular plane of the embossing. Their unique shape creates gaps between the leaves that allow the stiffeners to be welded accurately to the floor.

The sheets have a large number of cutouts, most of which fall in the factory welds, where the floor strength is the highest. The product is intended both for cars that, due to the passage of time, require repair or reconstruction of the original mounting, as well as for tuning purposes, to prevent their damage during intensive use during Drift, KJS, 1/4 mile competitions, etc.
