ULTRA RACING 2-point rear upper strut brace for Alfa 145/146

The rear upper strut brace ties the left and right rear strut mounts together in the boot or behind the rear seats, so they cannot move relative to each other under cornering load.

Fast cornering, hard braking and hard acceleration move the weight of the car around and twist the body – in a corner one side can carry up to three times the force of the other. A twisting body changes the suspension geometry, the tyres lose grip and the car starts to understeer or oversteer. ULTRA RACING braces stiffen the body exactly where it twists most.

• Vehicle: Alfa 145/146

Before series production the manufacturer tests every design on three jigs – compression, torsion and flex – and then on track. The braces are designed to hold the geometry in road and track use but to crumple in an impact.
