Chassis

Chassis parts stiffen the body shell and change how the car leans in corners. This section covers:

• strut braces between the suspension towers;
• lower, mid and member braces under the car, and side and floor bars;
• anti-roll bars;
• control arms, tie rods and geometry correction parts;
• engine and gearbox mounts, and roll cage padding.

Braces are described by where they fit and by their number of mounting points. A two-point brace links two points directly, while three-, four- and eight-point designs tie in more of the surrounding structure. Anti-roll bars are listed by axle and diameter, some with two or three settings, and approval details are given for many of the anti-roll bar kits.

Plan the chassis work as a set rather than one part at a time. Start with the areas that flex most on your car, usually the strut towers and the front subframe or lower arm mounts, then add braces further back. Bolt-on braces rely on the mounting points around them, so check those for corrosion or damage first.

Underbody braces reduce ground clearance and sit close to the exhaust, sump and jacking points, so check the clearance before ordering and after fitting. Lift the car only on the points the brace leaves free. Engine and gearbox mounts control how much the drivetrain moves. Firmer mounts pass more vibration into the cabin, so choose them with the car’s everyday use in mind.
