I want to put 5mm spacers on the front and rear….do I need to change out the wheel lugs for longer for this small a spacer?

 

Yes

 

Definetly.

 

Reputable kits should come with matching extended bolts

 

Use only the longer wheel bolts!!

 

On all my other cars, with 5 mm wheel spacers, I never had to change out the bolts with longer ones. What's different on a Porsche?

 

It’s just what they recommend. I’m sure has something to do with the # of threads engaged, and length of the stock bolts, optimized for weight or something. They’re ‘just long enough” as is - the extra 5mm gives full engagement on the threads.

The factory 5mm option comes with both spacers and longer bolts. https://www.suncoastparts.com/produc..._aLh4GgNPnIIIZ

This is the way to go.

Curious as to why you’re selling. Coincidently I just saw your comment on another wheel spacers thread from a few years ago where you just put them on. Side note: just changed my spark plugs with guidance from your YouTube Channel. Great channel and appreciate all your efforts.
