You have not lived if you haven't tried to run a stock '57 Chevy with manual steering, a bench seat, and no seatbelts through a slalom course. Imagine being dragged through the ocean by a whale, holding on by just a dorsal fin and you have a pretty good idea. You're porpoising up and down, getting tossed side to side, and hanging on for dear life. It's not pretty (and we had the benefit of radial tires!).
More than once we thought we were losing control and we were not going more than 30 mph. The combination of body roll and no belts saw us steering with only half a cheek on the seat most of the time. I was ready to reach for my Dramamine, except I didn't have any.
This car's behavior was fairly typical for the era, which is frightening. Ron Godel owns this beautiful 210. It's got a 283 four-barrel/three-on-the-tree combo and is just as the factory built it, save for the 8-inch-wide Corvette Rally wheels and Dunlop G/T Qualifier P235/60R15 tires. He loves the car dearly and takes it to cruise nights in north Jersey, but he definitely wasn't satisfied with its road-holding ability (or its definite lack thereof).
Fortunately, there are plenty of ways to improve the capabilities of your Tri-Five, from low-buck upgrades to a completely new chassis with late-model Corvette suspension parts. We went the simple route here and addressed the most obvious shortcoming-its lack of anti-roll (or sway) bars. We got front and rear bars from Hotchkis Sport Suspensions and in an afternoon made a serious upgrade to the '57's handling (and safety).
How much of an improvement? Our best time through the 420-foot slalom before the addition of the bars was 10.10 seconds. With the bars, we knocked the time down to 8.88. The mph rose from 28.35 to 32.24.
