Founder Beanoir™ Posted August 13, 2020 Founder Share Posted August 13, 2020 Reaching out to all the engineer types who might have a view on this. One part of any Porsche I've owned that pisses me off is the wheel bolts, they're just crap in the way they look unfinished when new and gradually look worse and then rust. I was looking at buying some new bolts and came across the Design Tek ones at Design911. The idea of a stainless bolt is great for aesthetics and longevity of the finish, but correct me if I'm wrong but I thought stainless of most grades is not suitable where there might be a high shear stress (or whatever the correct terminology is) on the bolt? Hence why advice is normally to not use use stainless bolts on suspension components etc. Am I missing something? The other option is a set of titanium wheel bolts, they look flipping lovely...only £270.... Link to comment Share on other sites More sharing options...
sevenfourate Posted August 14, 2020 Share Posted August 14, 2020 The Shear strength of stainless is terrible - ref: "stretch (and promptly snap) bolt" almost. Although Porsche wheel bolt torque isn't high (relative to many applications). ***I had to have a course on a piece of machinery fairly recently to enable me to do some bolts up to between 1500 and 2000nm...... But i still just wouldn't. Besides which. The Ti bolts do look sooo good. Not to mention all those ounces you'd save..... 🤣 1 Link to comment Share on other sites More sharing options...
Hunter Posted August 16, 2020 Share Posted August 16, 2020 Also incredibly interested. I had one "helpful" suggestion to put plastic covers on the bolts... Link to comment Share on other sites More sharing options...
Frayz Posted August 17, 2020 Share Posted August 17, 2020 (edited) Stainless steel is actually very soft and a poor use for high tensile applications. I like you hated the scabby wheel bolts so went with a set of titanium ones. The weight difference is staggering.

I’m seriously tempted... Link to comment Share on other sites More sharing options...

D911 - and a bit of OC discount I’m sticking an order in for them tomorrow, and some RSS engine mounts, gearbox bushes, wheel spacers, and...well, some other shizzle that I can’t even remember. 1 Link to comment Share on other sites More sharing options...
Budflicker Posted August 17, 2020 Share Posted August 17, 2020 Hi Nick Nice, i think I might need some as well. I had a quick look but couldn't see a thread on your 996? Tell me more??? Link to comment Share on other sites More sharing options...
CaymanCup_Chris Posted August 17, 2020 Share Posted August 17, 2020 How anybody gets away with selling stainless wheel bolts is beyond me. Titanium all the way, they’ll last a lifetime on a road car! 🤘🏻 Link to comment Share on other sites More sharing options...

And never had a 911, so a bit of an experiment too! 1 Link to comment Share on other sites More sharing options...
