Contis aren't as quiet as the Michelins, but face, it, these cars aren't quiet anyway. Generals are quieter than the Contis, in my experience.

And they're a bargain. https://www.tirerack.com/tires/tires...MRT43&i1_Qty=4

I generally like the firmer dampening of the HDs, but yes, there are certain road conditions where they do provide a bit of a harsh ride. Very well controlled, but harsh. Sometimes that level of control makes bigger dips less punishing than softer setups, though. Definitely a trade off.

I never liked FSDs. They don't seem to hold up as well for as long and they always feel just mushy to me.

I have loved every set of adjustable Konis I've ever installed for both myself and customers, whether it be Reds or the Sport Yellows. I tend to put them right in the middle of their adjustment range with stock springs, usually ever so slightly on the firm side of the middle to be accurate, and they have always provided an excellent, well-controlled ride and take a bit of the harsh edge off the ride compared to HDs.

The first set of Reds I ever installed I did what Koni said and set them fully soft. After about 2 weeks it felt like I was driving on 4 bad struts. It was pretty bad. And unfortunately with the reds, you have to remove them to adjust. I eventually did so, put them in the middle and was happy with them ever since. I think I recall the adjustment full soft to full firm was somewhere just shy of 2 and 1/4 turn. I'd turn it to the full firm setting, then back it off one full turn. Have been happy with that setting on every car I've used it on, but then again, I don't mind HDs in most situations... But even at that relatively firm setting, they're a bit more forgiving than HDs.

What I can say about HDs is they seem to last. They do indeed take quite a lot of punishment and never seem the worse for wear even after 150k miles. Most OE dampers are getting mushy by 50k...

I am running the Reds with stock springs and cupra bushings at the rear. No need for a rear anti-roll bar. The setup is a bit rough around town as our roads here suck. On the highway it’s perfect, straight as an arrow and easy to chew up the miles.

Most likely no, either up or down.

Struts won't make any noticeable difference, no. The tires might, but that depends on what you have on the vehicle currently.

I think there are tires out there that are lower rolling resistance still than the Purecontact w/ECOPlus, but they're a nice blend of having decent grip, tread life and not killing your fuel economy either.

They are an improvement if you were already running tires geared much more towards performance like I used to. Wheel size and weight is likely to play an even bigger role than tire brand and model, though.

One thing to watch out for on tires designed for fuel mileage, they are generally very light. Sometimes you can end up with weaker sidewalls, so you give up something to get something else.

I have to send in one of my MK4 rear FSD's to Koni for warranty, as it is blown.

Was looking at ID Parts and notice the FSD's are now being called "Active". Is this correct? https://www.idparts.com/koni-special...-a4-p-561.html

Also noticed the price has come way down. Set of 4 is priced lower than the reds or yellows, and about $275 less than I paid during the Koni sale in 2012!

Hope the quality has not diminished...

Yes, Koni has discontinued FSDs and replaced them with Special Actives. Same technology, same damper, still made in Holland, but red instead of gold and packaged individually. And the price is significantly lower.

Reds are not available for most platforms, so the MKIV is a bit of an unusual situation where both Reds and Special Actives are available. They are priced very slightly below the Reds, but I'm not sure how long that price point will be in place. For the e90 BMW, for example, they're currently priced below the Yellows, which I think will be the case for most platforms.

It'll be interesting to see what Koni does for warranty replacement on your FSDs. We bought all their remaining stock.

Thanks for the info Brian.

I hope Koni offers to replace both the rears. Only the one side is visibly blown, with oil all over it. Will update this.

Very happy with my Reds and the HD spring set. Towing my ~1400# teardrop for the last 1000 miles, performance and handling has been
exceptional. I did dial up my rear springs 25%. And I have the 23mm
front bar. Rock solid on the highway cruising 70-75, tracks great.

Great prices on the FSDs now, but I'll stick with what I've got.

Bumping up this classic thread. Great reading.
My wifes 13 tdi sportwagen has a broken rear spring, so at 110k miles, i am thinking shocks as well.
Does anyone have real world experience with koni special actives as a rear only replacement shock, while keeping the stock front struts?

This car commutes daily to Boston. No SoCal suggestions please.
Working on an idparts cartload, and im stuck at deciding rear shock brand.

Btdt with HDs and koni yellows on my Audi A3.

Probably OK to do Special Actives in the rear only, but it would be much better to replace all 4. Of course you could replace the fronts later.
