Wheel bolts

I'm planning on doing a wheel refurb soon & want to replace the tatty/rusty wheel bolts.

Can anyone recommend a particular brand or where to source them? I don't want them going rusty straight away!
 
Morning!

Drop us a message at Rushworth Performance (01384 895491) , we've supplied replacement bolts for a range of Porsche'es now along side wheel spacers and suspension upgrades.

We stock the full range of ST suspension parts which supply some OEM style loose ball wheel bolts ideal for replacing Porsche OEM bolts.

Cheers

Matt

 
I have a full set of 20 original Black Porsche standard length wheel bolts complete with locking bolts and key socket. They came off my 2012 987.2 Cayman R when new following the fitting of wheel spacers.

They are for sale and all are in excellent condition. Photo attached.

If you are interested, PM me for price and postage details.

Just replaced all mine at around £5.70 each from Design 911, original parts. Wish I'd known about Brian's black ones for sale, but never mind.

I also bought a socket from them that has a nylon cover inside and out, so won't scratch the wheels or the bolts. Their part number is SX03019.

Cheers,

Bryan

 
It is a pain that they rust ... there are titanium ones for anybody who is interested.

I ended up painting my rusty ones with grey zinc paint !

P.S. Does anybody trust the locking wheel nut to the elevated recommended torque setting for trackdays ?

 
Yes, Chris. I torque all my wheel bolts and the locking wheel bolts using the standard key socket to 118 Ft/lbs. (160Nm) Not had any problems at all.

I am always very careful to make sure the locking key socket is properly engaged before applying the torque wrench. A short extension is preferable to a longer one on the torque wrench to keep the 19mm socket square with the locking key.

160NM does seem high for the locking bolts, but I haven't had any problems. And yes, they do get tatty quickly 😭

 
When I replaced my bolts, I didn't bother with new locking ones. More hassle than it's worth, but I understand that's just my personal view.

If the new ones go rusty, it'll just paint the tops as it'll get expensive continuously replacing them! Mine old ones had also been tightened too many times dry, so was (perhaps overly) worried that they may be past their best.

Speaking of tightening dry, this https://www.ebay.co.uk/itm/222914290098 is the replacement for Optimol TA, recommended in my handbook.

Your handbook will also give you the correct tightening torque. I only know it's 130Nm for my 987.2 Cayman.

 
I have found that the steel ones from any source will rust quite quickly. However it only takes about 15 minutes with a rotary wire brush and a rattle can to get them black again. The paint dries in the time it takes to clean the inside of the wheels and, whilst not a perfect finish, will certainly pass the six foot test easily.

That socket wont protect the bolts, it has nothing on the inside, it is meant to protect you wheels as it has a plastic outer sleeve.

 
Locking wheels bolts … the adapter is the weak link, I `lunched` mine on a previous CR, totally my fault for not concentrating on Brian`s point of note. I replaced with an original standard bolt which then carried over to the 981CS. Tyre fitters have been extremely grateful for not being exposed to the `soft` adapter !

My wheel bolts are six years old, used all year round for the last three and are corrosion free / only slightly marked. I do not use any `lube` anywhere … just a wire brush on the threads and hub contact patches … with a wipe over using WD40 or electrical cleaner. Wheel to bolt contact areas are similarly cleaned / wiped.

Socket ... maybe this is ?

I use a standard socket, taped on the outside to help mitigate any misjudgements …

 
Before spending £20 on a single socket, take a look online they often sell the full set of common bolt sizes 17/19/21 in an alloy socket with a teflon cover (to protect your wheel paint) for sub £15

sometimes even throw in the breaker bar!

 
The paint on the bolts needs to be impressively robust to tolerate a socket, even a 6 point socket at 62 lbft torque applied even once, let alone many times over the life of the car, and on top you have the winter road conditions corroding away....

Just bought £6 of plastic 19mm A/F bolt head covers to decorate the nuts. will post pics when done.

 
As others have said, the locking wheel bolt adapter is a weak link - aluminium I believe - and I'm thinking of getting a spare just in case. Like Brian, I'm always very careful to ensure that it's engaged fully with the bolt before applying any load. Mind you, I'm more concerned that it'll strip when the car's in for a service or tyre change when the techs are using the windy power tools..!

Complaints about unsightly rusting wheel bolts seem to occupy a lot of space on these forums and it's a shame that Porsche don't supply or offer plastic caps for all the bolts, the locking bolts included (VW have a neat solution). Titanium bolts of both types are a very expensive option.

I bought a set of 20 titanium bolts for my Spyder at about £8 each plus post from Acer Racing

Not too bad for much nicer product
