Suppose a car has a base model and a performance model with bigger disk
brake rotors and more pistons in callipers. So one can stop better from
high-speed driving. So when one does a panic stop, there is a lot of
braking torque on the front wheels. If the front end is McPherson Strut,
it would seems to me that braking is going to bend the struts unless
they are built like Soviet tractors.

Brake torque force isn't borne by the strut:

You are correct that enhanced brakes, such as larger disk brake rotors and more pistons in the calipers, can put more strain on the suspension during high-speed braking. The increased braking torque can put additional stress on the front suspension components, particularly the McPherson struts.

During a panic stop, the weight of the vehicle shifts forward, increasing the load on the front suspension. If the front struts are not designed to handle the additional load, they may become bent or damaged. Additionally, the suspension bushings and ball joints that connect the steering and suspension components can also be affected by the increased stress.

It's important to note that most modern vehicles are designed to handle the additional stress of enhanced braking systems, and the suspension components are typically built to handle the increased loads. However, if a vehicle is modified with larger brake rotors and more pistons in the calipers, it's important to ensure that the suspension components are also upgraded to handle the additional stress. Also, regular maintenance of suspension components can help to prolong their lifespan.

It's always important to consult with a professional mechanic before upgrading your vehicle's braking system to ensure that the suspension components are compatible and can handle the increased loads
