Chassis Braces

About Chassis Braces

Bracing won't change how your car sits, and on a stiff coupe you'll barely notice it. On a hatchback, a convertible or anything with a big trunk opening, it's a different answer. A tower bar and a front lower brace tie the two sides together, and the steering stops feeling half a step behind your hands. Geometry only works when the chassis holds still, and this is how you make it hold still.

Where you start depends on the body. Front strut bars go in quickest and they're the ones you see under the hood. Lower tie bars and subframe braces do more once a car's lowered and stiffened. The load paths down there are carrying more than they used to. Rear bracing helps a hatch most, since a sedan's already got a bulkhead doing part of that job.

Weight and clearance are the trade offs. Steel weighs more than aluminum for the same shape. A lower brace can cut ground clearance under the front subframe, which matters on the driveway you're already scraping. We carry aFe Power and AWE Tuning here, and each listing states the material, where it bolts and what it can foul, intake and coolant routing included.

Common questions

Does a strut bar actually do anything

On some cars it's obvious and on others it isn't. A convertible, a hatch or an older shell flexes enough between the towers that a bar tightens up turn in. A modern coupe with a stiff body gains close to nothing beyond a tidy engine bay. If your car already has a factory bar, the aftermarket one is a small step up.

Which brace goes on first

The front tower bar, because it's a handful of bolts and you'll feel it on a flexible car. A front lower tie bar comes next once the car is lowered, since the subframe carries more with stiffer springs above it. Rear bracing is a hatch and wagon thing. Buy in that order and stop when you stop noticing a difference.

Do braces cut ground clearance

Lower ones can. A front tie bar or a subframe brace hangs below the subframe, and on a car that already scrapes that becomes your new lowest point. Tower bars and rear upper braces live inside the body and change nothing underneath. Each listing shows where the piece mounts so you can work out which camp it's in.
