Last weekend I was in the paddock at Mid Ohio and saw the (ultimately winning) Acura prototype with brackets and strings on it. That's what I was talking about.I've raced out of the pro paddock, not just been there. Have you been in an indy or nascar shop? They have laser alignment and setup rigs. Races are won back in the shop. They prioritize what needs to go on the road. Strings work, no doubt. But just because you may have seen them in the pits does not mean that is the preferred method.
