Im new here so bear with me, I have a bone stock 98 1.8turbo quattro. Ita nice car.....I like it alot.....been discussing/begging the wife to let me spruce it up but its been a loosing battle. Im now selling stuff on a certain *b*y site to get the money.....the things we do to make our rides nice. Anyways my question is Im thinking about 18x8.5 35et rims with 235/40/18 tires, will I have any rubbing issues? Should I lower the car first then get the wheels and tires? Or visa versa? When Im done with this I dont want to hear I told you so about mistakes so Im trying to get it right by asking all the questions and doing all the research I can......Thanks for all the input in advance.

Ouch. Im lucky my balls are never going to be in this kinda of a vise. I would lower the car first. Then you can let the suspension settle and have a real idea about what kinda issues you might have with rubbing.

Although Stampy seems to be in denial, he is right about one thing... lower it first. B5 A4 looks halfway decent lowered on stock wheels. The same CAN NOT be said for the opposite. [up]

<<edit>> to answer the first part of your post. yes, with those wheel/tires specs, you will most likely rub in the front with a lowered stance. Most choose to roll the front fenders (do a search on how to if you don't know) in order to run 235/40's. 35et is a good starting offset to get 8.5" wheels flush with the fenders both front and back.

Grrrrrrrrrrrrrrrrrrr.......Im barking up the wrong tree then.....Ive only been looking at rims and tires...not suspensions........time to do more research......thank you for your wisdom.

Now all you have to do is decide if you want springs and shocks or coilovers ......... [:D]

Coilovers give you the ultimate flexibility in ride height but springs and shocks are better on the wallet.

245/40-17 on 17x8 on stock sport suspension works for me.

Of course, if you don't have sport suspension (red struts) your car will look more like this.

@OP - it all comes down to personal preference. I suppose Jim's setup looks OK on sport suspension and is probably at a good, balanced, comfortable height for him, but for me, it's a tad too high. 18's would help fill the gap a tiny bit more, but again, it comes down to personal tastes.

if you don't have the factory sport suspension, then in my opinion, it doesn't come down to personal tastes... its just wrong.

I like it better about an inch lower too but it doesn't look bad at all at it's current height. It is a hell of a lot more functional than when it was too low to clear speed bumps and had no bump travel. Aftermarket sport springs on Konis would improve the look and probably ride better than (or at least as good as) the stock sport suspension.

Check to see if you've got the red struts. If you don't then definitely swap suspension before adding more grip.

Hmmmm I'm thinking functional. I like the race look but I know that the mean streets of an urban environment will rip out the suspension. I like Onemoremile's choice but do your tires rub with weight in the car?
A few questions, what did you have on before? have you gone lower and then reverted to the present?Will the suspension, rims and tires fix my body roll when changing directions at 100mph plus?

nyca4tq,

to answer your first question, yes an 18 x 8.5 w/ et35 will fit your car with stock suspension with out any rubbing.

Your second question is totally up to you. There are lots of people that will tell you that you have to lower your car before you put wheels on it. Yes, It will be much more visually pleasing if you lower it before any new wheel and tire set up. But that choice it totally up to you.

IMO A low profile tire with a stiff side wall will make it a tad more stable. But really nothing even close to a good solid suspension set up.

Better tires add more grip. Better suspension lets you use the tire's grip more efficiently. Stock suspension and race tires is quicker around a track than race suspension and stock tires. It doesn't work that way on the street though.

Anti roll bars (ARBs) are great on the street since they limit roll and keep more contact patch on the ground but still allow for most of the suspension's original compliance. They don't help with dive or squat but that is rarely an issue on public roads. Changing directions at 100mph plus on the street on stock suspension is well, stupid. Hell, it is stupid on any suspension. Any unforeseen variable like a sandy patch of pavement, an expansion joint, or a pothole can have disastrous consequences.

My front fender lips are rolled and sealed. I have no rubbing with the fatties although I did rub the liner before it was trimmed back. It was purposely left in the way so I could tell when I was getting within a half inch of the fender lip. I have carried four people and 500 pound of tooling with no rubbing. I've also had it lowered on balanced coilovers with no rubbing.

Down low on the track tires. The garage door trim is vertical. It was low enough that it had a lot of negative camber. That camber is what lets the outside top edge of the tire to clear the fender lip.

It is lower than it might first appear since the tires have no tread and are a numerically smaller diameter to begin with. They are at least an inch shorter than full tread street tires. Although this affects scrub radius a little bit it is still a great way to lower a car for the track without messing up the camber and toe curves from lowering too far. In reality, this is still about a half inch lower than what I believe to be optimum for the track.

Same height on the 235/45-17 Pilot Sports. The lot is sloped so it looks like the front is higher but it the car is actually flat on corner balanced coilovers.

And one more next to the S4 which is at it's stock ride height. I could probably roll a golf ball under my car but definitely not a tennis ball. It was way too low. Still, it never rubbed and the liners hadn't been trimmed up.

Decisions decisions........ok, Im convinced that a suspension is in order. Ideas? I want functional and relatively economical. From research, that would mean springs and shocks. Thoughts on brands? Pros and cons? I looked at the wheelmax site and there is a black b5 advertising rims, it looks nice......Im aspiring to that for mine, anyone know what setup that is or is it a really good photoshop job?Its a little too low for me but a good goal, if I miss I should be ok...

Konis are more comfortable than Bilsteins. Bilsteins are a high pressure monotube and are position sensitive. The lower they are the harsher they are. The high pressure design acts as a supplemental spring rate and results in a tendency to feel like they are crashing into bumps rather than absorbing them. This same effect also gives them slightly sharper response on the race track and the monotube design keeps the a little cooler since more fluid is in contact with the outer casing. None of the track advantages mean anything on the street where the surface is rougher and keeping the contact patches planted is most important.

Konis are more supple and are velocity sensitive. They are better on the street in every way that counts. The twin tube design moves fluid from one chamber to another through orifices that control the velocity of the fluid. That means they are much more lenient when it comes to small road imperfections but when something big hits they stiffen up in a hurry. Always remember that the contact patch has to stay planted on the surface to be of any use.

Hmmmmm....Thanks for the insight. My car is a daily driver and will not see a track anytime soon. So I'm now looking for springs and shocks, wheels and tires......this is not going to end anytime soon.........well here goes...wish me well.....Ill try to post pre and post setup pics....My DD will never be the same.....

Im looking here and found b5 s4 complete suspensions, are they lower than my stock setup and what are the implications and would they fit on my b5 1.8tq? Onemoremile seems pretty in the know about this subject, thoughts? Btw, nice ride....Im aspiring........

do a little search in the B5 section for "S4 supension" - it's been beat to death lately - fyi, it's not ideal.

FWIW I am switching my H&R Sport springs out for H&R Race springs this Sunday. I have only used them about 14 months and I drive less than 10k miles a year so there isn't much wear on them. I'll be posting them in the classifieds once I have them off. Price will probably be $150 or maybe a little less. I'll have to research what the going rate is. You can look in "my gallery" to see the amount they lowered my car. I am on Bilsteins also though. [up]

I checked around the classifieds and it looks like used springs are anywhere from $120-200. There are some good deals there, I would check it out if I were you! Also the wheel and tire classifieds usually have a nice assortment. You might be able to find a suspension and wheels / tires for a price even the wife can appreciate [>_<]

After many posts and questions and answers here on Az, I decided on spring and shocks vs CO and the pictures are below.

Now for the post HnR Sport springs and Bilstein Sport shocks and struts pics,
