vibrations after installing new shocks- ideas?

ouch. they should have at least brought to your attention that there were issues (assuming they didn't cause the issue by negligent repair).
so tough to find competent workers.......
You should at least see for yourself while the car is up on the rack (have them escort you if they insist), make them go over everything with your eyes on it as well. If you are not watching for yourself, too easy to report back that they were thorough even if they weren't.

So, they did fix the suspension issue with a new bolt then looked over the entire front and rear suspension for any other issues. apparently the problem with the loose bolt was with my mechanics assistant, who was distracted that day by "woman" issues. I told my mechanic that any girlfriend that causes so many issues in your life that you get distracted to the point that you forget to tighten bolts in a customers car has GOT to go. she's OBVIOUSLY no good. he agreed! I'm quite certain that if my mechanic had done the work this would not been a problem. That being said, now that he's apologized and fixed the problem on his end, I've had a chance to drive the car now for a week and its still vibrating much the same way it had on certain parts of the same roads. So, my next step is to take off the summer tire / wheels I have on there now and put on my winter tire/wheel set up. the winter wheels are stock Audi 18's with winter tires. I've NEVER had any issues with these wheels and tires. they are softer, more side wall and not as stiff, and the wheels are hub centric. If I don't get the same road feedback on these wheels and tires, then I'll know for sure its the summer wheels and tires that need some work. If I still get the same issues, then I'll know its something with the car. That seems to the easiest way at this point to start diagnosing the problem. I'll let you all know what happens. maybe I'm just going to feel more imperfections with these wheels and tires now that the suspension is stiffer. dunno. we'll see.

changing one variable at a time and making comparisons sounds like a good way to start. remember that the stock rims use ball seat lugs (not sure what your summer rims use, most aftermarket are cone seat).

no change by swapping my 19 inch konigs and Supersports to my 18 inch Audi rims with winter tires. (by the way the konigs are not hub centric and use plastic rings), but even with stock Audi 18 inch rims on soft winter tires, still getting weird vibrations I never got before. having oil changed at dealer this Friday. will get their take. I guess "could" be just the new stiffer shocks picking up every detail on the roads. dunno. Every review I read of these FSD's say they ride BETTER than stock OEM shocks- for just about every application- ive been on just about every makes forums and FSD's are very highly rated. especially for comfort and taking care of the small bumps and inconsistencies on roads. maybe they need to settle? like new springs do... Its a mystery. I wonder if I had put any type of new shock on there if I would have the same issue. Being that any shock would be stiffer than what I had- 95K stock OEM non- sport audi shocks. Might have to live with it. I really don't want to put OEM style bilstein B4 on their to see or the stock SACHS shocks because I'd be shelling out even more $. and not sure if I can take back the FSD's just because I don't like the ride. well, I'll update if the dealer finds anything on the suspension and let you all know.

I raised the suspension to stock and all the problems went away if your looking for comfort on your ride. I have Koni fsd and I adjusted to dampness to medium and have stock 17in wheel on the A6. When the car was lowered and had stock wheels it was bumpy and stiff because of the shorts springs. At least that was the case for my car. Try dampening the struts for softer feedback.

the fsd's are dampening adjustable. you must have the koni sport yellows? anyway, they still suck on smooth roads. went to dealer Friday, and just like my mechanic, Les Schwab and Discount tire- nobody could find ANYTHING wrong with any of my existing suspension components. Just must be the shocks! I just sent an email to the seller to see if they would have mercy on me and take them back even though I'm beyond the 30 days return policy. we'll see. I may take FL 6.5 avant up on your offer. Really wish I could get some stock OEM shocks with same , less than 1000 miles on them, in trade or for sale. I'm guessing these have "maybe 700 or 800 miles on them by now.. really disappointed in the ride on smooth roads with the eibachs, 19's and supersports. guess I need to go back to softer mushy OEM style shocks. never had these issues when I originally put on the eibachs with my stock shocks at around 7K. and then put on the wheels and tires too. same thing- none of these issues. I guess the FSD's don't like the combination of the eibachs and aggressive 19's. Its weird because a LOT of aftermarket retailers sell the FSD's and eibachs together as a kit... doesn't make sense if you get this kind of reaction on the roads. its been very weird and I'm not pleased with it. I'll keep everyone posted.

Yeah I have the yellow on where you push the strut in and turn it counter clockwise for dampness. It's the springs and I was disappointed just like you thinking car would ride better lowered with stock tires. What happened to your stock springs? I had to buy mines brand new about $630 beats paying $800

Doesn't look like the seller wants to take them back. Koni says they can inspect and test to see if they are to spec and fix if not and send back, but I'd have to send them all to Koni and in the mean time I don't see how I could drive the car. Its not a good situation. I do have stock springs, but not only would it be a lot more $$ to then put on the old springs, but the car sits way too high. I will need to swap out shocks anyway so there would be some costs for that, but no, I don't want to put stock springs back on. the car rode fine the past 5 years with the stock shocks, 19 inch wheels/tire and the eibachs. Its only been recently that I noticed the wear on the OEM's with diving and floating. But I never experienced this weird vibrating on smooth roads with slight variations in the road surface. I really think the Koni shocks just can't handle small variations in the roadway with these particular springs. maybe with stock springs they'd be ok, not sure. But since I have no interest in replacing springs the shocks will need to go. FL C6.5 Avant ... are you still interested? if so what price were you thinking? I'm guessing I've got maybe 800 miles on them now give or take a few. I paid about $595 for the set new I think- I'll have to see the exact numbers, but around $600. If I do sell them I'll be putting stock spec shocks on it- Bilstein, Boge or Sachs. at least the OEM style shocks are a little less $$ than the Konis so that might make up for the extra cost to have these taken off and replaced. Won't be purchasing a Koni product again.
