Be wary: That nice "cold metal" becomes a first-degree skin burn appliance under the summer sun.

That's just part of the real metal experience!

Looks nice. I think the FE hit would bother me, however. Question: Your profile says you have an '02 Wagon. The rear bumper looks like an '03. Which is it?

You can see in this photo the '02 bumper is shorter.


BTW those are my 15" Koseis. 13 lbs.

IBW rolled over 374K miles this morning. Still my favorite. It's shameful, the other cars just sit around.

My Jetta wagon TDI is a 2005 with 130k miles.

I was hoping the Fat Five wheels wouldnít be too much of a hit in fuel economy or acceleration. I just put them on and filled the tank. Iíll get an idea today as I hit the highway for five hours. If the FE hit is severe, Iíll probably have to search for some light 16Ē rims. I would like to avoid going back to 15Ē wheels...too much sidewall flex when cornering.

Going from steel to aluminum even with the increase in diameter could net a fe improvement. Though without a scale this is all just conjecture.

15" steel wheels weigh 22 lbs. VW/Audi alloys are notoriously heavy, with a couple exceptions. Avus 1s (15") weigh 16.7 lbs. But I bet those fat fives are close to 30 lbs.

You may not see a big change in FE in highway driving. The difference is usually greater in suburban or traffic, where you're accelerating and stopping the wheels frequently.

Whe I used my TDI on the track I had a wheel tire set that I used to drive to the track that weighed about 40 lbs. (wheel and tire). The slicks I had were on forged wheels, and each wheel/tire weighed 32 lbs. When I swapped them out the difference in acceleration and braking was immediately noticeable. Unsprung weight really matters.

I thought I read somewhere in the depths of the internet that Audi Fat Fives weigh 21.5 lbs.
I didn’t have a scale with me, but the Fat Fives did feel slightly heavier than the steel wheels.
I agree on the importance of unsprung weight.

I don't have the experience to do something like that now, but I'd like to keep my '01 FORVER so it'd be nice to see how it's done right.
i can do that. i am in the process of fixing the 2.slow for my 91 cab. it'll most likely be next summer though when i start the swap process. have to get my shop opened up first.

Use the kit for drills. Worked wonders on mine. These are dirty but after a month still looking good.

Default Maintenance and more maintenance

Well, today (and yesterday), I did some maintenance on an 03 Jetta Sedan that I purchased last January, 2018. It's not tagged and insured. I've not had the time to attend to it until now.

The engine is from an 01 and has 302k miles. The car has 252k miles on it.

So, I re-sealed the Injection Pump, removed the Starter for inspection, cleaning & lube to get rid of the run-on whine. I also changed the air filter, cleaned the plugged snow screen and changed the cabin filter.

Below are a few pics of the work...





Below, I was trying to take a close up to show the location of the "shim" that may fall out if you pull the head out too far. I did this job with the IP on "low cam." It was fairly loose, but the shim stayed in place.



Below, starter disassembly pics.









Below, is a bit of air filtering maintenance...







Next up is, tranny oil change, fuel filter change, oil & filter change and set the Injection Quantity. And, it is less than 3,000 miles from a scheduled 100k mile TB job...

i also received the head set for the 2.slow yesterday. so maybe this next week i can get teh little beasty up and driving. i will also be installing my 02 radio in it as my tdi is getting a new bluetooth Pioneer double din with backup camera.

Nice photos. Looks like you traversed the entire cleanliness spectrum from "Operating Room" to "Yuck!"

.
I later found another place on the internet claiming the Fat Fives to weigh 26 lbs. Not ideal.

Also, I drove 304 miles yesterday and used 7.4 gallons of diesel, which equates to 41.1 mpg. Not bad but it does seem about 2 mpg lower that what I'm used to calculating. There was some city driving and construction traffic in the mix.

Do you have any opinions on the VW Goal 5-spoke wheels? I think those weigh 20 lbs., according to the internet.
Otherwise, I'm open to lightweight wheel suggestions in the 16"-17" range.

I like them but if I'm thinking of the right wheel the bolt pattern is 5x112, not the 5x100 that your car needs. If you want 16s or 17s, finding a wheel that's 20 lbs. or less would be a good target. If the fat fives weigh 26 lbs. then you may not be able to do a whole lot better. Tire weights vary a lot, too. I've seen 16" tires for our cars that vary between 22 and 28 lbs.

I have a set of Motegi Traklites that I bought for my track day car. 16x7.5 and they weigh 12 lbs. Now that's light. No longer available.

My first thought was we were discussing MPG values in the "who cares" range.
Turns out I was wrong.
