Hi guys, would appreciate your thoughts on picking best front sway bar. Car:1970 GS455, stock driver, not raced. I understand too much sway bar can be a negative. so what would be better. a solid 1 1/8" or a hollow/tubular 1 1/4"? Hvramesq/hector
The bigger the better on the front. I have a 1 3/8” bar on the front of my GS. Out back is the HR Partsn stuff rear bar.
I’ve got a set of Spohn bars on my 66. 1 5/16 front and 1” rear. Really helps to compliment the handling with the 18” wheels and big tires. Steers like my 70 camaro when it was mildly built. Still have to change the steering box to the quick box I got from Hector. That along with extra caster should change it even more.
I put Trans Am 1.250 bars on all my cars, big block and small block. They were not designed to handle that great in the early 70s nor for radial tires or better alignment. Put a 1.250 bar on the front, the stock rear and get as much positive caster as possible in an alignment and you've improved the handling 100%. Urethane bushings would be an easy upgrade on the front bar. Tall upper ball joints will give even better front end geometry for not a huge investment.
All factory bars that fit early A body cars were all solid to my knowledge. You'll have to go aftermarket for hollow. Much more money.
