Sport quattro head washers for ARP head studs

[terrybullwon]

would titanium be a suitable alternative material?...

I'll have a set mate if your going titanium!

[JP]

Titanium is a non durable material and will not be suitable for application. Even titanium retainers have a finite live compared to stock steel ones

ARP

TITANIUM: ARP now offers special order fasteners made of Ti6Al-4V that is specially heat-treated and provides superior strength to other titanium alloys employed in racing and aerospace. The material has a nominal tensile strength of 180,000 psi, and is very corrosion resistant. The main advantage of titanium, of course, is its weight – which is about 40% lighter than a comparable fastener made of steel. Head studs and accessory bolts are ideal applications for this lightweight material.

Interesting unaware of the advances. Always known titanium to be a non permanent but lightweight alternative. Titanium rods with titanium bolts anyone

If you have to ask the price, then you can't afford them......

I just used original washers. They are tried and tested, and free.

i have asked bambridge to have a look for us, hopefully he'll get on the case and can knock something up.

Depending on price may be interested in multiple sets.

Since we are on the topic, this is from my bulid thread...


This has been discussed a few times on here, are the ARP head washers supplied in the kit too small? I'd say YES

Here are a few pictures of my head after a few hundred miles and the difference between ARP and Sport quattro head washers.

For info...

ARP size
Outer diameter 19mm
Inner diameter 11mm
Thickness 3mm
edit: - surface area = (pi * (9.5^2)) - (pi * (5.5^2)) = 188.495559 mm2

Audi washers p/n 035 103 377 12 off £1.03 each
Outer diameter 22mm
Inner diameter 11mm
Thickness 4mm
edit: - surface area = (pi * (11^2)) - (pi * (5.5^2)) = 285.099533 which is roughly 66% more than the ARP!
