Ride quality even worse than expected. Advice welcome.

Ah man, now I feel all inferior and wimpy with my .99 TB's. And I thought going from .87 TB's was a jump. I gotta get the biggest I can!!! :rofl:

I will say, with the .99's and RCD's it sure rode nice on the one drive I've had. Had'em for years, came in a parts car, and glad to finally have them in the car.

I don’t think there’s anything wrong with running 1” bars. But it depends on the whole build. Ride height plays a big part of that. The tires being used are a big part of that. For a car relatively close to the stock ride height and using 15” rims and the street legal tires that are available for those, 1” torsion bars with aftermarket sway bars will work well and you’ll have a car that handles far better than they ever did stock. I think the 1.03” PST bars are a great choice for a street car with some mild updates to tires, braking, etc.

But it does depend on the build. Lower the car significantly to take advantage of better suspension geometry and you need larger bars to increase the wheel rate to deal with the loss of suspension travel. Improve the tires by running wide, high performance compound modern tires and you need more wheel rate to deal with the added suspension loads that come with those tires. Run shocks with modern technology and vast improvements from what was available even 10 years ago and the larger bars have much less of an impact on how stiff the ride quality is. There isn’t a new car on the market that rides like one of these cars did back in the 70’s, and that’s a GOOD thing.

Suspension has to be matched and tuned to work properly. That can mean large changes to the suspension components with relatively minor changes in application. I’m not saying everyone should run 1.12” bars on their street car, they shouldn’t! I usually recommend not going bigger than 1.03” for guys that are keeping 15” rims. You just can’t get street tires with enough performance in those sizes to need bars much larger than that. But that also doesn’t mean a car that’s been set up for more aggressive handling can’t use them successfully.
