For one thing you need to listen and feel for the vehicle. Most suspension systems are only good up to about 110mph and most tires are only good at 130mph. Exceeding any of this causes excess vibration that you can feel, which becomes unsafe.

Tires are the most important thing because they are your contact with the ground and absorb most of the road noise. If a tire blows out at high speed bad things will happen. Fortunately I have never had a blow out.

Shock can also come from poorly balanced tires and a loose steering column. Everything needs to be tight and well balanced.

When you are driving fast you need to be hyper aware of what’s around you. The biggest risk are other drivers so always provide tremendous amounts of space. Driving fast does not mean driving aggressively. Do not change lanes often to dodge around slower cars. Be aware of upcoming interference to the road, such as construction.

If the experience does not feel safe and you do not feel in control of the vehicle you need to drive less fast. My first fast car was an experimental Mitsubishi Galant with a tight racing suspension. The engine was an unimpressive regular 4L engine, so it did not accelerate fast and maxed out at 135mph. But handled high speeds extremely well such that the suspension was most smooth at 110mph without excessive road noise until over 120mph.
