I forgot about lightweight wheels, those can net you some gains as well, find a set of decent 14" rims in the junkyard? Going 185/60-65r14 will open up your tire options tremendously as well. There are documents out there that list the more common junkyard alloy wheel weights if you do some searching, people have compiled extensive lists of potential weight saving bits for all the lemons races.

The 13" steels I have are lighter than my 14" snowflakes and the snowflakes are supposed to be the lightest alloys VW made. Also, it takes a ton more to turn the 185s than it does a 155, there is 30mm of extra rubber making contact.

14" lacastlets are lightest stock 14 i know of... passat/jetta/cabby come stock... passat syncros got 15" version that one day ill own a set of...

they supposedly a funch and forged... people polish the faces into a mirror... even has aluminum center caps ($60/each new years ago) but plastic ones from snow flakes fit nice.. but if you have 4 caps.. well worth polishing effort.. just most are missing 1.. :P i have 5 due to matching spare.. but my 5th one is discolored.. i bought a set of wheels with a melted one for caps one day.. :P

also the inners have different colors.. of my 5 2 are one shde of grey.. other 3 are really light colored..

the lightest made were 13x5 mk1 rocco wheels... here.. in europe they came in a more common 13x 5.5 and usa got as option for 80-81.. and jetta only.. ive seen only 1 in real life.. 1 not set of 4.. 1.. and imo of all the 13" my fav.. id rock a set.. seen a few pop up on poortex on "just picked it up" type of cars.. the owners always feel its just a rocco wheel till i point out i want to own.. then they relize its not "common" and never see again... vs the 5" wide wheel.. the face is almost flat.. i got pic somewhere..

To my knowledge, these are the lightest rims VW ever made. They are 13". I own a set, well I guess my brother does and I know of one set for sale. I have no before and after mileage report though.

Yeah I think you are correct CRSMP5, I've gotten them mixed up.

I'll be darned. I never knew any of those good ol' Sca-rocco wheels were 5's!
Man, it's GREAT to have cramps back! ;D

id almost swear they were magniesium they weigh so little.. but the bubble butt effect the 5" wide has vs the 5.5" flat has always put me off.. the 3 piece 15" ones the guy is building look sweet... but i bet the flate face with less dish would look much better..

http://meister.us.com/

would be a guy to ask on weights..


i know there a tranchula cut up.. few "man holes as they call them" but he has a set of 13" snowflakes, guess mexico option, seen set of turbines someone wanted him to do.. so id ask them if your dead set on wheel weights..

now imagine less lip, flat face... no way ill ever piss away $3k on wheels.. id buy a mill and make my own first.. but they pretty..

:D thanks on the welcome back.. but a majority of us were only 13x5.. the 13x5.5 were jetta only option in usa for 80-81.. then they got turbines, rocco/cabby got a 1 year only really soft bend if 5ft from pot hole wheels.. 83 tranchula replaced.. then snows, bottlecap, teardrop, p spoke was 87 gli option here, cross pond had on mk1s.. castletts started in 88 along with steel 14s..

so to me growing up with new just out.. yea till mk3 i know them.. :P sadly the only 1 of the 13x5.5 i have seen was so bent i thought they bent the face.. tire shop fd up and was looking for one.. hell this was 84ish..  only one ive ever seen in person.. :(

Oooo those are shiny. Yeah I need to invest in some cheap light rims sometime. I'll keep my eyes pealed. Id love to make my own wheels sometime. A light one off design would score me points for having one of the kind rims and be killer for mileage ;) too bad that won't ever be haha.

How do you guys drive in town for best efficiency. I catch myself compression braking and riding in third too much. I really need to take advantage of that 3+E ;) in computer cars (at least scubies) compression braking shuts off the injectors and saves fuel. But in our cars it would use up energy with no fuel savings so I should just clutch in coast right?

no the way the gov. works in our pumps if you coast in gear it limits the fuel. If you clutch in, not only are you riding your clutch, you are wasting more fuel.

At 3,000 rpm or so if you let of there will be little to no fuel injected. If it were, you would never slow down coasting. It is something about the flywheel weights. IIRC rabbitman or someone had a test with their tiny tach that around 3,000 rpm when they let off the tach quit since there was no line pressure activating the pickup.

Ok, I follow you now... idle fuel quantity at 3000rpm, vs idle fuel quantity at idle rpm (coasting).

Descending a hill , I get EGTs around 200F as long as it's steep enough to keep it over 2800 rpm I think.
Burn and engine kill is going to be more efficient, but the factory ignition switch  can make it a pain.

Okay so our pumps DO limit fuel    at around 3k Rpm idle. Now if only I had a tach so I didn't have to do calculations on the fly haha.

Any other big increases in mpg? I know the driver is the biggest factor but making these things slippier has to help.
