I borrowed the picture of a 1953 from Jalopy Journal. It's not mine but it's a good example of things that can go wrong after steering modification. The priority is good steering and good brakes. If your insurance company finds out that you personally modified your steering, they will be reluctant to pay for any damage (property or personal).
Excellent advice! In 40+ years of seeing and paying losses like this, I can reiterate if your insurance company discovers after a loss that you took it upon yourself to re-engineer your vehicle's steering or braking and didn't tell them and let them (or usually a qualified outside party of their choosing...like Jerry for example) inspect it, the likelihood they'll cooperate with a claim is not good. Usually they'll reserve their rights...meaning they'll send you a letter saying they'll defend you initially but may later deny coverage (depending on their investigation). Best situation is that you bought a kit (from somebody with a corporate insurance program) and had it installed (by an experienced professional who also has insurance).
