Her Mars Red 83 Urq ...23psi of manual boost...vid

[Quattro v1.0]

I just looked at my RF's, they are ET35.

I'd sure like to see what winter package Ur-S fuchs look like.... Never heard of such a thing.

[Hank]

Hey Dad, my Mercedes RF's are et32s. With the 225-50-16s, I had no rubbing issues with coil overs or stock springs/terrible shocks. I have only rolled on fender on my URQ as of now with 245-45-17s, and they only rub in the rear on big bumps. I also have 15mm spacers back there to make it look nice, but they can be removed and then nothing rubs. Mind you that the 17s are et45s.

I would do 225s like I did for that car and not look back.

As for color, I would just paint them a silver. Dave did a super rattle can special on the set on the s6, and they turned out presentable surprisingly for having black under htem as well!! He just taped off the centers and went. I have two other centers here at the shop, though I do not know where they are atm. The fourth is broken sadly. THere were a set on audifans not two weeks ago for 35 dollars in perfect condition if you wanted to go that route.

I still have to hold my ground on the 215's Hank. He won't be sacrificing any rubber on the road to a 225 and proportionally they just outright look better than the 225's. Most 225's will just show too much sidewall giving the visual impression of a taller tire than you actually have.

FWIW my speedo reads dead nuts on when checked against the GPS as well, I have no comparison for the 225's though. Last time the car was driven with the RF's and 225's GPS hadn't been invented yet lol

[Hank]

Last time I measured GPS to the Speedo, it was dead nuts on! Perhaps your teeth were rattling against your skull at 4000rpm on the freeway, and you could not get a good look at your speedo/gps

No 3000lb sports car should have 215's on it, period. While manufactures vary, the jump from 215 to 225 is usually more than 3/4" of contact patch to the ground.

It has always irked me that aluminum is always painted over. I like the look of raw aluminum, but obviously it has to be protected from oxidizing. It seems along the lines of taking a cherry wood table and painting it. Just doesn't seem right. I may have to clear them just to see and if I don't like them I'll just call the clear primer and paint them silver.

On the tire size question I have always not really liked the look of sidwalls sticking out a lot further than the width of the tire tread. Obviously it's the edge of the tread that is going to rub so that total width has to be watched. I just don't like the looks of not enough tire, for the width of the wheel. Hank I thought that you said that you HAD to run the spacers with the A8 et45 17's. Anyone know the offset of the Urs4 wheel. I'll look when I get home in the morning, but I'd be interested in how close they are to the RF's. It sounds like your MB RF's should actually rub more than Sean's et35 RF's.

Are the center caps still on audifans?

[Hank]

I have to run spacers in front ( almost 15mm) but not in the rears. If I took out the rear spacers, there would be no rubbing issues.

I thought the URs4 wheels are et35s, but I could be wrong.

I believe that the Fuchs that came on Ur-S cars were all part of the winter package.

I don't see how a 215 will look correct on those 16x8's from the urS. I ran 225/50-16's on the CQ for several years on a 7.5" wheel and it looked "correct" on the wheel (IE sidewall basically flush/co-planar with bead "lip"). A 215 starts looking stretched, I have 215/45-17's on 7.5" wheels as well. I can't imagine going up a 1/2" and running a 215. It isn't like you are going to be running a 225/50-16 DOTR tire that is really wider than the numbers suggest (my DOTR's in that size that I use for auto-x are more like a 235)...

[quattro87]

That's kind of what I was thinking Eric. I not only don't like the look of a stretched tire on too wide of a rim, but I can't believe that handling would be a good either. Are all DPTR tires like that?

[Berserker]

Stock 16x8 S4 fuchs offset is ET40. I ran 225/50R16 DOT R (BFG R1) rubber on them on my UrQ and needed at least a 5mm spacer up front to not get rubbing on the tie rod boot.

The "winter package" wheels that I think are being talked about are 15x7.5 6 spoke speedlines.

[quattro87]

Do you think that non R compound tires in 225/50R16 would rub the same way with ET40 offset? It seems that if they would clear the tie rod that it would be better for rubbing on the fenders.

If the "winter package" is the speedlines, that wouldn't be bad. I like the wheels, just not in 6".

[Hank]

We have a set of speedlines at the shop too that were going to be tossed if you are interested, but they are 15s.

Your original Urq wheels?

[Berserker]

http://www.s-cars.org/postnuke/modules/ ... /002_G.jpg shows the winter package speedlines I'm thinking about.

As far as 225/50R16 non DOT R rubber fitting, I do have a set of Eagle F1 GSD3 tires for the UrS4 wheels that are ready to go on, but I need to get my wheels cleaned up and repainted, too, so it will probably be a while before I could test fit for you, as that's low on the priority list right now.

I did get rubbing in the rear over big bumps and under hard cornering with no spacers in the rear, and I've rolled my fenders, but the rubbing occurs on the upper mounting screw for the rear valance.

[quattro87]

Nate, you better move that kind of stuff up the list if you are going to make the Las Vegas GTG. Oh and did I mention that we would really like you there! When you are here I could just look at them in person.....oh but wait, I'll need to have tires on by then and will probably know myself. Did you roll both front and rear? Thanks for the link.

[Dave]

John, the speedline hank has are the same as in that link:

[Berserker]

I know, I know, I should do the Vegas gtg. I'm deciding between that and a trip over to Germany/Belgium right now. After I talk to my Germans this weekend about their schedules and if they can accomodate me for a couple of weekends, I'll make the decision between one and the other. If I do Vegas, though, there's about a 10% chance that I'd drive out, and a 90% chance that I'd fly.

[quattro87]

Well Nate, again we would love to have you even without your car. :(

Dave are those speedlines 16x8?

Does anyone know the color code on the stock wheels? I think that after coming home and looking closely at the imperfections of the casting on the wheels that I have bead blasted I'm leaning towards silver paint again. The spokes aren't perfectly flat and have spots that show the grain so trying to get a uniform semi-gloss look on the spokes will be hard and with just clear coating you would see everything. I guess now would be to find the silver to match the center caps. Anyone?

[Dave]

no they are 15x7.

I wouldn't worry about matching the center caps. Like Hank mentioned, they can easily be spray painted to match. just a little tape over the emblems and it they will match whatever you spray on the wheels.

[cuatrokoop]

That's kind of what I was thinking Eric. I not only don't like the look of a stretched tire on too wide of a rim, but I can't believe that handling would be a good either. Are all DOTR tires like that?

Any DOTR or full comp tire is generally wider than a same-size street tire because of the construction and, well, if you have a class limitation on tire size, then you can gain a little bit by being selective in your tire choice and racers know this. I think H noted that his race tires were almost an inch wider than the same-sized street tire. I know when I set my 225/50-16 Dunlops I used to run next to the 225/50-16 Yokohama DOTR's, the Yokes were visually wider. They are also quite a bit wider than the 225/45-17's on wifey's A6q (17x7 wheel), those tires are barely wider than the 205/55-16's on the A4...

[Hank]

The 225-40-15s R compounds I have are as wide as my 245-45-17s, and they also do not rub anywhere on the car at any point of driving style.

[quattro87]

no they are 15x7.

I wouldn't worry about matching the center caps. Like Hank mentioned, they can easily be spray painted to match. just a little tape over the emblems and it they will match whatever you spray on the wheels.

I was still in the clear coat mode and knew that bare plastic wasn't going to look like raw aluminum. :tard: I did put the one center cap I have on the doctored (Irozed) wheel I was getting ready to clear coat and it looked like it would have matched just fine unless the aluminum changed colors real bad when cleared.

I have to say the 245/40/17s that are on the TT never seemed very wide and even less so on Emily's beetle with those big round fenders.

[Quattro v1.0]

Nobody has convinced me yet...

I had the 225/50's on an UrQ, and I have 215/50's on the car. I completely prefer the 215's both aesthetically and for fitment.

It's not like anyone has teased me after looking at my setup... unless y'alls talkin about me once I leave ;o]

If anything, a lower profile 225 could be considered, but a 225/50 just don't look right in the fender wells of the UrQ.

John, if you are going to run those H&R's on that car, you will NOT want 225/50's on there I promise you.

[Hank]

<blurts out> I think the 215's looks skinny on your car Sean.....

Can I barrow them for the salt flats in two weeks. I hear skinny tires are the ticket...

Whats your hovercraft doing on the freeway with other 80's supercars?

[Quattro v1.0]

nope, not drinking the kool-aid

looking at the side of the car, 225/50-16's look like 70 series all-seasons...

Hank, this tire/wheel combo is not going on a 500HP stroker UrQ... Im sure you can justify all the spacers and fender banging for that extra 5/16" of tire, but on the car which is staying a 'daily' drivable car it's just not necessary.

All the fender rolling in the world isn't going to stop the tires from rubbing where the rear valance screws to the fender. Take a look at the rear valance of my former UrQ in your Dad's garage, you will see where they rubbed away the plastic...

I can't make anyone do anything, only offer my opinion based on the experience I had with that setup on that car.
