16:1 vs. 24:1 steering

16:1 is quite heavy at parking speeds
20:1 was the standard fitmnet on all RHD cars i.e Baracuda for UK Japan south africa Australia

i.e the aussies used it in Dart bodies and their shorter A body front B body rear width charger style body. It was considerd perfectly fine on standard 6 1/2 or 7 inch wheels

I run 225 65 R14 radials with as much castor as i can get on a short Aussie Charger and to be honest 16:1 is a pig at parking speed However the benefits on the motorway/freeway and around the lanes and backroads greatly outweigh the fact that i get a bit of a sweat on when stopping for groceries
