Anyone with deep offset & no spacers?
 

Just wondering if anyone is running deep offset wheels without the stock spacers? Does this work? Pics of the rims?
Thanks
jack

These Kodiak's were built to fit without spacers.

Hi Brian, Does the SC take the same offset as 930 without spacers? I was thinking they would look deeper with no spacers on a 930.
Thanks for your help.

Yes, RH copies of the speedline wheel for the '94 3.6 turbo will fit 930 trailing arms with no spacers.
I don't think you can buy them in the right offset to do that though, but maybe.

I bought a set of used 3 piece 18" RH 3.6 wheels in 930 offset that had bent outer rim halfs. The rears were 10" wide and made for runnning with stock 28mm spacers.

Then bought new 1" deeper RH outer rim halfs from Jim Dorociak and rebuilt the wheels myself.
Now the rears are 11" wide and fit good with no spacer with 315/30x18 tires.
The shape of the wheel center has plenty of room for the caliper with no spacer. And plenty of room for the fender and oil lines along the right rear longitudinal.

This is the right rear.

JFairmann when you remove the factory 930 spacer, where the wheel studs to long to use the factory lug nuts ?

Yes they would be but the alloy lugnuts that were on my car when I got it were hollow on the end so the the stud sticks out the end of the nut.

I cut the origonal studs a little shorter so they wouldn't stick out the wheel holes but not all the way down to the nut. If you ever need to use the spare tire it won't fit over a rear caliper without at least an 18mm spacer underneath so I carry one on top of the spare tire and I left enough length on the rear studs to be able to mount it if i had to.

Me too, no spacers:

Einpresstiefe means Off-set (Note that rear is negative)

I am looking to get deep offset wheels for my widebody car as well.

Can the same be done for the fronts? The rears look awesome!! Is there any down side?
Thanks
jack

The Kodiak's on my old red rocket pictured above were made for early 930 with no spacers. The rears fit my '85 930 with no spacers but the fronts do not as the late 930's have wider front spindles.

Jim great comment about the spare tire I never would have thought about that!

I really like not using spacers for many reasons and see no issues with it.

Hey Brian, How about sharing the reasons? Some of us green horns would like to know. Want to order some wheels, & want to get it right the first time!!! Thanks a lot for all your help.

Spacers:

1. Extra weight--particularly the worst kind, unsprung
2. If you need thick enough spacers, then you actually need adapters with extra lugs (or you need to swap out your stock lugs for longer ones, if available). If you use adapters, then those cover up the stock 5 lugs and you can't see the lug nuts holding them...in case those lugs underneath loosen or have other issues.
3. Using spacers to a certain degree puts a longer moment arm on your suspension, which puts different (higher) strain on suspension parts than originally engineered.



Here are the Zuff wheels I'm running on my stock spacers. I suppose you might even get more dish if you ditched the spacers and built the wheels to fit:

Sorry, I guess thats what I was talking about. Taking the stock spacers off and used deeper offset wheels. Is there a down side? Does the front use spacers too? I am talking about later 930s.
Thanks
jack

Early 930 has spacers on front, later does not. Found that out the hard way, ha!

The reasons I like no spacers is:
> Deeper dish.
> Ability to custom space each wheel 'cause you have long studs.
> Why didn't they just put on wheels that fit?
> Balancing, non-OEM thick spacers can cause balancing issues.
> Hub centric spacers seal themselves to the hub with time becoming difficult to remove.

JFairman, The Falken tire that you use 315-30-18 ,I can't find them online, can you get some info please, thanks

Just make sure the wheel centers you use leave enough backspacing for the brakes.

Yes, later 930s eliminate the front spacers (but keep the rears).

From whitsh year they dont have a speiser in front?
Mine is a -79 and have 22 mm speiser in front.
And a 28 in rear.

Jocke.

They're Falken Azensis RT 615.
Pretty good tire and I don't know if they still make them.

If you take off the spacers on a 930 you will need to replace the studs to shorter ones by 28mm or have open end ones if you use wheels designed for a wide body 911 or 911SC and try to use on a 930. As Brian@ Rarly8 said "I found out the hard way" and I still have the wheels on the shelf. Was going to see if thay could be used on a race car, to mount rains, etc, however could not find suitable rain tires for the 16 inch rims. They are 8 inch fronts and 11 inch rears

All my earlier pics with Fikse wheels and these latest Forgeline wheels are all tailormade to perfect fit without spacers capable of running 265-18 front and 305-18 rear both in 930 turbowide & Strosek Ultrawide bodies... 9" front, 11" rear.

Hi guys I am located in South Africa and have jjust recently rebuilt a 1981 930 Turbo. There are a couple of things that I am not happy with. I have rebuilt it original and everything on the car has been replaced or refurbished. A complete nut and bolt rebuild. I have terrible turbo lag, the turbo only comes in at 3500rpm - what can I do to reduce this?
I have had the original 16" Fuchs rims refurbished but would like to get a set of deep dish matbe 17" rims for it. Any ideas??http://forums.pelicanparts.com/uploa...1328020462.jpg

Boost spool: Not much if you stick with stock components.

If you're up to upgrades there are better turbos, headers and exhausts which will lower the spool.

I've yet to be able to find out for sure what rim halves are required to accomplish deepest reasonable offset without spacers using Fuchs centers. The wheels I bought don't have the correct offset for stock 930 and I'd like to order the right rim sizes. While yes I can and have done plenty of measuring there's nothing like learning from other's successes and having confirmation of what actually works.

No spacers, stock studs:

The Kodiaks I have that were made to use on an early turbo with no spacers require 1" spacers on the rear of the widebody SC and none up front. The fronts of an SC are the same a the early fronts of a 930 with the spacer removed. The late 930 front is the same as the early 930 front with the stock spacer mounted.

Shifter 125, those wheels look great. The stance of the car is perfect.

Does anybody here with 3 pc (9 & 8 x 17) Fuchs conversions like mine photo'd above mind advising me what rim halves setups you have? Mine are all wrong for my 930 and would like to know specifics of what others have that work on their 930 (please note if with spacers retained and their thickness).

THANK YOU in advance!

There is 5.75" of front spacing available on the rear of a 930 with no spacers, and about 6.75" of back spacing. If you are using anything less than an 11.5" wide wheel (which takes up 12.5" of space) the front spacing is all you need to be concerned with in order to push the wheel out so that a tire correctly sized for the wheel will sit flush under the lip of the flair.
Here is an example:

Hate to dig up an old thread, but I have a question. I don't know much about wheels, but on an 88 930, would a 25 mm offset on the front and the rear wheels work?

Here's a spreadsheet I made a while back, but like anything you need to confirm your dimensions before ordering:

http://forums.pelicanparts.com/uploa...1340202075.jpg

Thanks for the spreadsheet. Now for the questions. So from the chart i'm getting that an 8 inch wheel with a 25mm offset for the front wheels will not work without a spacer, correct? Although a 10 inch wheel with a 25 mm offset for the rears will though, right?

+1 thanks for the spreadsheet. I'm hunting for something that will look good and have tires available for an '85 euro. Love the Zuff but there seems to be some drama involved obtaining in those.

Me on the way back from Le Mans the other day....... I quite like it :D

I recently took delivery of these Fikse FM5s. They are spec'd to run without spacers in the rear. I don't have any pics yet of them on the car as I still need to get tires mounted. I would have really liked Zuf Fuchs replicas but was not ready to deal with the delivery issues for that kind of dough. The Fikses took about 10 weeks from ordering to my doorstep. 5 spoke has the right classic look to my eye, and I had them made with anodized finish rather than polished to more closely match the factory look.

...no spacers:D

Since yours is an '88, the 8" will work without a spacer which the car shouldn't have stock anyway but be in a little. The 10" rear will work with the stock 28mm spacer but will be out a little so you'd need to check fender clearance. I think.

It's always best to check what you have since you can measure your current wheel's backspacing and the clearance inside and out to know which way you need to go.

So it would push the wheel out 12mm more than the stock wheel correct?

9.3mm

Okay great, thanks.
