Default All those with an ST bar on an EF: what's your mounting choice (problem: 1990 Si with clunking in re

On any 89-91 Civic hatchback, CRX, there seems to be 2 mounting points for the Suspension Techniques Rear Sway bar:

1: The ST provided shock mounted brackets, that locate the endlinks at the point where the shock mounts to the LCA.

2: Using the stock sway bar's mounting points on the LCA to mount the new ST bar.

Which do you have/ use and which do you prefer, if you have tried the two different points?


I'm asking because I have a 1990 Si hatchback with the ES bushings kit, minus the shock bushings, falken azenis on stock steelies, and the stock (14 yr old) shocks and struts, as well as a Suspension Techniques' rear sway bar. During any hard or extended (long) RIGHT hand cornering, I get a nice "clunk" from the rear suspension.

Looking at the ST sway bar connection, using the recommended shock mounted brackets, my bar's endlinks are very close to the bracket on the driver's side, but have a good amount of space on the passenger side. (The threaded part of the endlinks is what would touch the brackets provided by ST).

Has anyone experienced such a problem? My ST bar sits slightly crooked, and clunks on only hard or prolonged right hand turns. I have the bar set on the middle setting, and the car is very neutral with only the slightest hint of oversteer, when I push it hard at the auto-x, which works better for me than taking it smoothly.

Check to see that your bar is not knocking on your exhaust.

It certainly might be. I had to cut the "stock exhaust" which had been replaced once in its lifetime by the 40-yr-old who owned the car. I had to move the stock exhaust about an inch towards the bumper so It wouldn't interfere with the sway bar.

I had a greddy sp2 on my crx which has some mega 2.5 inch piping and it would knock on one another all the time. My solution was to bend the exhaust hanger a bit and get a prothane poly exhaust mount. That solved the problem for daily driving. But on track days it would still hit. No biggy though....as long as you know the problem and it isnt doing and permanent damage

You wheel coming to full drop when it lifts off the ground can be causing this sound.

Thats why you hear in right hand turn cause with you in the car it tends to body rule more to the left.

Ok, problem solved. Just move the whole brackets and frame around in a hit and run!
