I'm having a hard time finding other options for my current setup since it's getting a bit harsh on the L.A. roads I travel. I only ended up lowering my car since my new 18"s with 40 series tires had a huge wheel gap.

98.5 B5 A4 2.8 FWD
I have currently: H&R Sport/Koni w/18" RS4 Replicas & PZero Nero M+S 225/40/18.

Have had in the past: Eibach/Bilstein (The front end began to settle and sag down and rubbed on speed bumps/driveways)

I've been told by the dealer that OEM Sport springs won't differ much from the OEM non-Sport height. What about S4 springs?

I'm just looking for anyone who can recommend a more comfortable setup OEM/Aftermarket? Would going to 17" wheels/45 series tires help my current setup?

S4 springs is NOT the way to go. They will be too high.

Going to 17s would help, but first check what is your air pressure. Many people do get 18s to work with similiar setups.

You should have gotten coilovers to begin with - this would allow you to raise the car when the springs begin to sag.

Are you willing to roll fenders? Is so then the perfect option for you is a set of 235-40-18 tires. Extra sidewall will make them softer. Secondly, next time you buy tires make sure they are NOT XL rated. SL - Standard Load is fine for your car, and they will be much more plush.

What air pressure is recommended for my tires 225/40/18 on a B5 2.8 FWD? I've been told around 38 psi is good. My tires are SL rated also, so I'm fine there.

But do you think next to going 235's, I should change my current H&R Sport/Koni setup? If so, any recommendations?

Thanks.

you can run what is on the door jamb (or is it the gas cap door) ~34 or 36 I think. You may feel slight difference. Going to 235 will help a tiny bit as well as you get more tire.

I really do not know where to go next. Koni coilovers are supposed to be pretty soft, and you can adjust your height to your hearts content.

I have found 18s on my S4 with Vogtland COs to be very complaint. But then I hear people think they are harsh. Again, Koni are know to be soft... so I do not think you can get much more improvement over what you have.

It's been a while...but a suspension specialist did the install. From what I remember it was 3/4 from the firmest setting on the fronts & 1/4 from the softest setting on the rears.

36 psi was for the stock 205/55/16's. Doesn't it change now due to my new 225/40/18's? Numerous people on the forum say with these tires they run 38-40 psi.

But overall even if I change the psi & go 235's and roll fenders, I don't think there is any other option other than going back to stock springs/shocks. I'm doing a lot of searching and it seems that for the B5 A4, it's either you have stock/high ride ht./cozy, bouncy ride...or aftermarket/lower ride ht./sacrafice the ride quality.

I've got the rears set to full soft. Even at 1/4 turn up from full soft it got fairly unbearable as there just isn't enough weight back there.

3/4 from the firm and 1/4 from the soft, aren't these then set equal?

I'd soften up the rears.
