Re: lowering rear tl system

There is no adjustment that only works the rear other than the short compensator bars--and they were there to compensate for luggage and passengers toward the rear. The principal of the suspension is the car is essentially "balanced" like a teeter totter on the long bars with the center of the car being the neutral point. How high it rides overall is determined by the amount of twist and strength in the bars.

Early on it was determined that there was enough manufacturing tolerance between bars and differences in accessory weight that cars could be either tilted to one side or heavily accessorized cars could be low. The different length links were made available to adjust side to side and make sure one car didn't ride higher or lower than another. A change in weight distribution at either end will upset that balance. The addition of the compensator bars to bias the back was mostly to ensure the tail didn't scrape the pavement when loaded.
