any place to source bolts/backings, lips, torque specs, are the bolts alrite to reuse?

are these a true 3 piece?

 

That's the info I don't have


I have emailed the manufacturer, I'll let you know when they reply

What does the etching say on your rims?
Does it say "Speedline for Porsche" or "TechArt by Speedline" ?

I don't think the TechArt etching is available anymore

The "Speedline for Porche" are still available, but there's a slight difference - Speedline is written in upper case on the original rims, but on the replacement ones the "i" in Speedline is lower case - other than that they're the same

I'll see if I can find the name of the stockist for you

They are true three piece wheels
The perimeter bolts are rated as 10.9 strength

Minimum Tensile Strength is 150,000psi
Tensile strength is the maximum load in tension (pulling apart) which a material can withstand before breaking or fracturing.

Minimum Yield Strength is 130,000psi
Yield strength is the maximum load at which a material exhibits a specific permanent deformation


Minimum Proof Load is 120,000psi
Proof load is an axial tensile load which the product must withstand without evidence of any permanent set

 

I 'think' the bolts are M7x37, but have heard others mention 35mm before

EDIT - Forgot to add, the bolts are torqued down to 15-20lbs

 

I had the same wheels on my 993. They came standard on the 1995-993RS and they where built for Porsche by Speedline and they are rare as they were only sold for one year. If I recall they had a laser etched outer barrels "Speedline for Porsche". Speedline also marketed the wheels directly but I believe they were heavier than the Porsche versions and were produced for several years. I don't know about the Techart versions. What I didn't like about them was they were a 17" center with the extended barrels used to increase the overall diameter to 18". I sold them due to both the weight and looks issue. Before you spend any money on them, have them spun to make sure the inner and outer barrels are true. Replacing just the hardware is about $400 labor plus the cost of new hardware. If you have to replace all the barrels, you could be looking at $2k. This is not the simply DYI job you might think. It takes a certain amount of experience to reassemble the wheels to keep them true and balanced.

 

Thanks Duane

The labour cost is not an issue as I will be doing the majority of it myself
I've rebuilt a few split rims now

The thing I'm trying to find out is if the original bolts are still available (incase I snap any) or if i'd need to replace the lot

 

Ok, I have received a reply from Speedline UK saying Speedline Italy will not provide any parts for Split Rims

They said I could always try contacting Porsche??

Hopefully I'll get a different reply from Speedline Italy

 

Neil - I emailed Mike

He said £145ea to do the whole job
Or £125ea if I completely strip them myself

 

I have sent you a PM with the source where you can get the parts.

 

Received - Thanks

Yes, I have used them before

I was hoping to either replate or replace my perimiter bolts for genuine speedline items but it looks like I might not have that option

If I snap any I'll be using the guys you mentioned again
