I always use the TCI axle and 4 bar pieces.
They sit low and handle well ...
Some years ago, Rod & Custom magazine had a article about a road test. It was Gray Baskerville's 32 roadster Versus Jerry Kugel's Jaguar IFS/IRS 32 roadster. Baskerville's roadster beat the Kugel roadster in a few areas. Overall the test was considered a draw. A well set up 4 bar dropped axle car handles very well.
BOTH ... the 32 roadsters are well known in the Hot Rod world ... and BOTH are in the Los Angeles area.
