I would not expect a shock that was designed to work acceptably on a stock suspension to be anywhere near matched in rate to a very heavy t-bar rate like a 1.14" diameter. The 1.14" bar has a rate that is 50% higher than a 1.03" T-Bar, and around 170% higher than a stock diameter T-Bar. So installing a shock designed with a lower rate, is going to give an underdamped suspension response to bumps, and an underdamped response will be 'jiggly'. So just mentioning that some cars ride well with 1.12" t-bars is not a complete answer without also knowing the shocks used.
