Anything wrong with using spacers with my 6s and 7s?

[cantdrv55]

I don't spend any time on the track or autocross. Car s purely for street so is there anything wrong with using spacers? How do 6 and 7 with spacers fill out the wheel wells?

[Arne2]

I've got 1" (25mm) spacers on the rear only, fills out the flares nicely.

[cantdrv55]

Nice!

[Hetmann]

No problem.

I have 21mm adapters on rear of my 88 with 7's. Correct me if I am wrong but I believe spacers only have holes and adapters have holes and studs saving one from having to install longer studs in the hubs. Anyway, the 21mm adapters fill out the wheel well nicely with no fender interference at all. My son has 18mm adapters on his 85 with 7's. All this at the rear.

Same here. Using 1.25" H&R hubcentric rear adapters--look great and pulled the wheels out even with the fender edge.

I have several sets of spacers if you need. pm me.

Where does one purchase a 25mm spacer?

[Richard C2S]

I thought there was a "rule of thumb" that spacers of more that 10mm shouldn't be used as the wider spacer will put too much stress on suspension components.

Just my $0.02.

Separately, to Cattler, how do you like those Michelin Sport A/S tires?

It's fine in this case. If 8, 9, 9+ wheels are ok on the same susp you're not introducing any greater loads...

i used 23mm adapters on my rear 7" fuchs and was quite happy with the results.

What about longer studs? Seems like a 25mm spacer would require some more threads to grab.

There was a debate about this in another thread. I think the issue is that it puts more torque force on the wheel bearings and would likely shorten their lifespan. There are some geometry differences to where the vertical centerline is when you're using a spacer/adapter than when you're using a wider rim. Now, it makes sense on paper but I'm not sure how quantifiable it is that the wheel bearers go out sooner. The way I look at it, I've got a 30 year old car so they're going out at some point anyway so at this point when they do I don't think it will be premature anymore. I put 23mm adapters on my rears. They bolt to the existing hub and have their own lugs attached so you're not losing any thread. I believe they are H&R brand.

I'd like to put a set on the front but have been reluctant to do so because of potential for wheel rub issues. For now it's "on the list". Would love to hear what others have done to the front on an SC and if it was necessary to roll the fenders.

I used a 1' hubcentric spacer on my 88, and it made all the difference in the appearance. I needed longer studs which I was able to just get on without taking any major components apart.

[Jerome74911S]

I put .25 inch spacers on the front (6.35 mm), and 1 inch adapters (25.4 mm) with their own lugs on the rear. I've been running them for a couple years with no issues.

I like them a lot. I put those tires on the car shortly after I bought it in 2007--had them installed at Costco during their Michelin sale. My advice there is to talk to the tire shop manager, make sure they have someone they trust (a lot), and make an appointment to have them installed. I've put ~20,000 all street miles on them and they're barely worn. When properly inflated the car rides really, really well.

I haven't had any suspension issues at all.

And then there is the question: Do the spacers improve road handling or are they just improving the looks?

Typically, there are only two reasons for spacers. To allow the fitment of rims that would not fit otherwise, or appearance. Some claim that widening the track helps handling, but I don't believe it much myself, any such improvement is likely to minimal to measure, much less feel.

In my case, it was just for looks. Some day I may get wider rear wheels to get the look w/o spacers. But for now the spacers do the job.

[911pcars]

There are spacers that provide substantial width increases, and most are adapters that attach onto the existing lug nuts and provide their own lug studs in their spacer-adapter - sort of like a mini-hub. I think they begin at around 21mm.

Other spacers are thinner, on the order of 4 or 7mm wide. Be aware that merely slipping these (or a combination thereof) over the stock lug studs (between hub and wheel) will reduce the thread contact with the lug nuts and thus pose a potential safety issue.
