Current set up is factory turbo twist on WB.
Am thinking about putting 7mm spacers on all four.
I read from prior posts that 5mm definitely is fine with factory studs, 7mm 'should be' OK (but haven't found anything definitive), 10mm will need longer ones.
Anyone running 7mm spacers front and back w/o needing longer studs?

Elephant Racing makes the following statement on its web site:Quote from: https://www.elephantracing.com/porsc...spacers-studs/

However, they do not specify if this holds true for both steel and the softer stock aluminum alloy nuts.
A quick call to them would clear this up.

You need longer studs.

Up to 7mm is fine, just use different nuts, steel or titanium. I have had them on my car for 10 years.

I ran 7mm before without issues.

With original lugs? Getting ready to install 5mm up front and 7mm in the rear so am curious what is the right way to go ...

P-daddy

Yes, I used original lug nuts.

Thanks, P-daddy.

Not only does anything larger than 5mm need longer studs but make sure you are using hub centering (hubcentric) spacers otherwise all the load is carried by the lugs and not the wheel carrier.

Both untrue Im afraid. Maybe for bolt on wheels like 996 etc

If you want to take the chance but I have seen people sheer the studs off using 7mm spacer and not use hubcentric spacers. The lug bolt to stud conversions on the later cars are a huge risk.

Do you happen to have any photos of your car with the 15mm and 7mm spacers installed? Ones with the stock suspension would be even better. I did see the old thread where you had just installed them but unfortunately the photos didn't show up anymore.

I'm going for FD Motorsports 7mm hubcentric spacers.

When you put a wheel on a car with studs and not bolts holding it on, as long as you dont tighten one nut up to 200 n/m before the others, the nut will pull the wheel centre on the stud due to the ball end they have. Done properly there is no need for hub centre spacers on studded hub cars, as I said, with wheel bolts they do come into their own more. I have been using 7mm shims with standard studs and alloy nuts for 30 years and unless all failures have been so catastrophic that no one survived to give me a bollocking I have never had a problem. Steel wheel nuts should give you 100% piece of mind
