By increasing rigidity, steering response is greatly increased and body roll decreased. Handling performance is increased by helping to transfer load from one side to the other while minimizing understeer during hard cornering. BLOX Racing strut tower bars are made from extruded AL6061 and are 100% solid internally, unlike many other brands that offer hollow bars.
BLOX Racing has designed its bars with specially placed and specifically sized holes to help minimize weight without compromising the bars structural integrity and strength. Although other brands' hollow bars may provide some weight savings, they still cannot provide the rigidity of solid aluminum extrusions. BLOX Racing includes laser-cut and powder-coated flanges.
Simple and quick bolt-on installation. Available with and without holes.
