Bouncy Suspension

[unqstnd_answers]

Really need some help/suggestions.

I recently installed Tokico Illuminas and replaced the rear suspension bushings with the Prothane bushings. I also replaced the rear differential bushings with the aluminum/poly ones.

The problem is that when I set the Tokico Illuminas to a soft setting the ride can get really bouncy almost like I'm on a boat. I have no idea what springs were previously installed but I can fit about two fingers between the tires and the body. I'm guessing the problem is with the springs. I don't have much money because of the recent installations, but I'm a little concerned that the shocks might get ruined due to the constant oscillation.

If I set the shocks to a firmer setting it does alleviate the problem, but I feel like I should be able to adjust them to any settings without any problems. The car is a little too low for my tastes so if I could I would change out the springs.

What do you guys think, IS it the springs?

Bouncy = underdamped.

Soft setting = less damping.

I'm not seeing a problem here.

The problem is that it also occurred at the 4 setting. I just need some clarification If the problem is with the springs or is it something else. It was really bad.

I have the shocks set on 5 now so I'll see if it happens again tomorrow. Like I said I don't feel like I should be confined to just one setting. If the problem is with the springs what kind would you suggest? This is my daily driver and I drive the car at least 80 miles everyday.

Sounds like bad shocks to me. We're the illuminas used?

Blown shocks, then. Not surprising if the car was over-lowered.

I drove it on the 5 setting it was really firm, handled great no bouncing. It only happened at a random point on the 4 setting not the whole time. so a fluke? I bought the shocks used with 300 miles on them. The person I bought them off was replacing them with megan coilovers. I tested them out before I bought them and they were in good condition. they've only been installed on my car for about three weeks.

Sounds like blown struts to me.

I agree. blown shocks my dude. id keep them stiff until you can swing a new pair.....

my agx's with eibach springs can become a super boat if i put it on the white setting which I think is the softest so I dont think yours are really blown. It could just be the setting you have on. Also I noticed if I put the fronts to a soft setting and the rears to a stiff setting, the ride gets much smoother and handles better in my opinion. Another thing I wanted to add was the yellow setting which is supposed to be right under the stiffest setting feels bouncier than the green which is supposed to be a softer setting. Idk maybe im mixing up the labels .

The adjuster on those is a two-way bleeder in the head. If random points on the adjuster behave very differently, then they're more than just blown; they seem to have a problem in the bleeder. That could cause lots of bounciness because a wide-open bleeder would mean almost no low-speed damping.

In any event, junk them.
