would these bolts work on a .1 997 C2S with aftermarket wheels?

I have TE37 which need a ball seat like the OEM wheels. Our studs are 28mm and these are 27. I wonder if that makes a significant difference. Also our bolts are 19mm hex head. This is 17mm hex head which I don't think should be an issues

any thoughts? I just want that burnt titanium look and cannot find any

I think you should do a little more research on cone v. ball - I'm not 100% positive but those eBay lugs look more conical than ball (radius) seat - compare them to OEM and you'll see. Maybe this will help - lots of info if you Google "cone seat vs. ball seat"

 

I know the picture shows a cone seat. I suspect they just used a generic picture but the description says it's a ball seat. That seller also sells cone seat bolts

 

Has anyone here done race stud conversions? basically using these http://www.race-studs.com/servlet/th...e-Studs/Detail and adding your choice of lug nuts.

 

I bought studs here for my 996. Very happy.
Make sure you get the R14 radius nuts for Porsche wheels.
Torque for studs are 26ft lb with blue locktite at installation.
Wheel torque is still 96 ft lb.

 

Porsche has changed the torque to 106 and it's retroactive to anything that was 96, so I have heard, but do your own research.

 

Interesting. I have been torquing to 90. I'll have to retorque everything soon

 

those look so awful i don't even know what to say.

very honda circa 2005 ish.

 

Do your own research is right...not sure where you found 106 but here's what the 2012 service manual says:

Silver wheel bolts (up to model year 2011) = 96 ftlb. or 118 ftlb. also permitted retroactively.
Silver wheel bolts (as of model year 2012) = 118 ftlb.)
Black wheel bolts = 118 ftlb.

 

Probably 106 came from being right in the middle of 96 to 118. 106 being a happy medium between the old spec that was around for decades, and the brand new one. I honestly forgot where I got 106 but I must have felt good about it because I have the number written on my torque wrench!

 

Go studs! Best <$200 I've spent on the car hands down. Mounting wheels is a treat, makes using spacers simple, AND it makes cleaning in the bolt hole when washing so much easier.

Mine are Apex competition 65mm Race studs and Pro series nuts. $167.97 shipped.

I like to give credit where due and I am a happy customer.

 

107 would be in the middle...maybe you saw the Newton meter equivalent to 118 ft lbs which is 160 newton meters.

 

Follow your owner's manual. I just wanted to say, for the sake of the OP, that the torque specs have changed, and you'll not find it in your owners manual of an older car. I shouldn't have specififed a number if I wasn't sure. 22 foot pounds seems like a huge jump, eh?

In the old days I just stood on the tire iron for a second or two, so 96 seems like nothing to me.

 

Very slick AWay, and not much more than a new set of Porsche bolts!

 

Have you noticed whether or not the black zinc coating is flaking off?
