Best torsion bars for Daily Driver/Road Racer

The 1" JS bars are really too soft for "performance handling" on a road course.

Don't get me wrong, they're a good upgrade from anything stock, but if autoX or road courses are in the plans I wouldn't bother. I think the 1.03's are about the minimum for that application, and I even balked on the 1.03's when it came to my GT and went with FFI 1.06's, and it likely will be a street only car.

Take a look at what the guys running road and autoX events are running. Autoxcuda is running 1.14" bars (320 lb/in wheel rate). GmachineDartGT is running 1.04's last time I checked (250 lb/in wheel rate). Tomswheels's runs 1.06's on his Valiant, 72BBSwinger has 1.06's on his Swinger. Tim Werner's 68 Valiant had 1.22" bars (350+ lb/in)!!!

While a rate on the 1" JS bars isn't published, I'd bet it's no more than 200 lb/in based on the experience I had running them, probably between 190 and 200 lb/in. The 1.12" FFI bars I have now are 300 lb/in.
