Is it ok to mix spacer sizes, say 5mm front 10mm rear? Do you all think 10mm stick out too much in rear?
I do want to add spacers but I don't want to stray too far from the original look but at same time fill out wheel wels a bit more. I will be getting base 991 w 20inch Carrera classics. Since the hight of the non-pasm base is a bit higher I want to avoid it looking like its on stilts, if you know what I mean. Thx for opinions. -jb

 

It would be appreciated if you would give us a shout about how you feel about both options.

 

5mm front 10mm rear will be ok.

 

Porsche sells the 5mm spacers but who do you recommend for the 10mm spacers and lug bolts?

 

H&R and some other companies make 10mm spacers. All they are is a piece of metal so there's really nothing special about one company versus another. I wouldn't buy some cheap $25 Chinese made spacer of course since I'd be suspect of the quality and whether they have accurate tolerances, but other than that, like I said it's just a piece of metal!

A few points:
1. Installing spacers is about as easy a job as you can possibly do on any car. Putting in a new air filter or changing a bulb is harder!
2. An alignment isn't necessary after installing just spacers.
3. They are really just an appearance option and they're not going to do anything to improve your handling. The increased track isn't enough that you're going to notice any difference, especially since 99.99999% of Porsche owners never push their cars anywhere close to their capabilities, which is the only time you'd notice such a subtle, tiny performance change like wheel spacers will give you.
4. It's normal on a Porsche to run front spacers that are about 1/2 the thickness of rear spacers.
54. You can normally run anything under 10mm in the front and 18mm in the rear with a stock suspension and wheel setup without any rubbing issues. Anything with my quoted numbers or larger may require rolling your fenders or changing your camber. If you're running non-OEM suspension or wheels, what size will fit will depend entirely on exactly what setup you're running.
6. On a 911, typically people run roughly 5mm front and 12mm rear with OEM suspension and wheels to get the flush look that's desirable. These are rough numbers since there are spacers in lots of different sizes, different OEM wheels available, and it will vary slightly between NA, Turbo, wide body, and what generation 911 (993, 996, 997, 991) you have on what exact size will give you the best flush look.

 

Unfortunately, H&R only make the following sized spacers to fit the 991:
5mm, 7mm, 14mm, 15mm. I am waiting for them to make a 10mm set so I can get them for my rears.

 

Has anyone tried the 14mmm spacers on the rear with stock wheels and tires? Results? Comments?

 

Seems like these would be easy and cheap to make at a local machine shop.

 

call me crazy but I like the look without the spacers.

 

I've always wondered, do spacers increase unsprung weight dramatically to the point of feeling a difference?

 

They weigh so little that the effect on unsprung weight is negligible- beneath the threshold of feeling and much effect at all.

 

Anybody tried the Ichiba or H&R spacers? Feedback/comments?

I still can't find 10mm spacers for the rear - only 14mm. Anyone found any 10mm?

 

Do the H&R spacers attach to the hub with the two little screws like the factory spacers do?

 

My experience w/aftermarket spacers.....

Use anti seize grease on the hub centric ring + make sure there are slots cut in the back side of whatever brand you purchase to help in removal.

Even w/anti seize sometimes they get wedged on so tightly they are tough to remove w/o slots in the back side.

You can see the notch cut in the photo on the backsides of the lower left & right spacers.

 

I ran those Macht Schnell spacers on my M3!
