New titanium Lugnuts ran me about $290 from EAC Racing and they go great on the front and using 5 mm spacers with Ultraleggera HLT 19" wheels, however in the rear the 25 mm spacer has studs protruding from the spacer mounting surface -- it appears studs use a nut to secure the wheel itself. Is there any solution out there where I can have spacers, 25 mm, and use these black titanium Lugnuts?
Just make sure your lugs seat into the spacer as deep as the bolts do and you will be ok. If you go to the track with those bolts I'd use steel lug nuts and not aluminum nuts.
To each his own. I'll save the weight. Just like taking out the passenger seat, and rear seats AND sound deadening AND carpets.....MPSS tires here too. Nothing Chinese. I hear you but.....weight saved is hp. These lug nuts look better and are stronger, and BLACK......sexier and stronger than the Porsche parts!
Titanium bolts are best known for being strong, lightweight and corrosion resistant. One property that stands out when compared to other metal bolts is that titanium bolts have the highest strength-to-weight ratio with a density of 4.51 g /cm3. As an example, titanium grade 5 is 4 times stronger than 316 stainless steel at nearly half the weight. This makes titanium bolts ideal for applications that require both lightness of weight and excellent strength such as oil & gas (down-hole), military and sporting goods.
Titanium bolts are also unique among metals in the chemical processing industry for handling chlorine (wet) and chlorine compounds in aqueous solutions. Titanium bolts are fully resistant to solutions of chlorides, hypochlorites, chlorates, perchlorates and chlorine dioxide. As a result titanium bolts are often using within the chlorine related industries such as pulp and paper and chlor-alkali / bleach.
Titanium bolts are also an excellent material to prevent seawater corrosion. Because titanium bolts can resists corrosion by seawater up to temperatures as high as 500°F (260°C) as well as survive at ocean depths over a mile below the surface, titanium bolts are used throughout the oil & gas, desalination and marine industries.
Titanium Grade 5 (Ti 6Al-4V)
Known as the “workhorse” of the titanium alloys, Ti 6Al-4V, or Grade 5 titanium, is 2x stronger than titanium grade 2. This alloy offers high strength and light weight, useful formability and high corrosion resistance. Ti 6AI-4V finds many uses in the aerospace, medical, marine and chemical processing industries.
Titanium Grade 5 Specifications: ASTM - B265, B348, B381, B861, F467 and F468, AMS - 4911, 4928, 4935, 4965 and 4967, MIL-T - 9046 and - 9047
H&R Trak+ series have what you want. They bolt onto the existing hub with included lug bolts, and have threaded holes for your existing lug bolts to screw into. I've used 30mm versions on my BMW X5.
An example 30mm version is below. Also checkout Adaptec - they are a site sponsor here.
Ok. I saw those....Adaptec too. Thanks! 15mm max though? ECS is good chit and bolts are black as in front now. The previous owner put some cheap spacers on this car front and back. I'll replace the fronts next, 7mm. If ECS sucks then, I'll go adaptec black uses the factory lugbolts.
15mm is usually the max spacer thickness you can through-bolt, which means using a longer Lug bolt that goes through the spacer and threads into the hub. Any thicker spacer should be a setup where the spacer bolts to the hub and the Lug bolt for the wheel is threaded into the spacer.
With my widebody Cayenne project where I need to move the wheels out to fill the flares, I'm going to be using spacers like this and sourced them through Adaptec Speedware. The problem is that it's difficult to find the thinner thicknesses of these type and only Adaptec had them in the 20mm and 25mm thicknesses. H&R model DRM spacers start at either 30 or 35mm and their DRC model actually Convert the bolt pattern from let's say a 5x130 to a 5x112.
Not knowing what the optimal look will be for my Cayenne, ice actually bought 20, 25, 30, and 35mm widths to make it perfect.
Also, check the length of thread protrusion with the bolt in the wheel seat to make sure the length doesn't exceed the thickness of the spacer as it will bottom out against the rotor hat and not allow you to properly torque the bolt and securely fasten the wheels to the car.
If you end up going with a 15mm spacer and need longer Ti Lug bolts for those, I have a set of World Motorsports ones for sale in the Marketplace.
We offer a similar design that allows the user to keep their factory stock lugs on this kit so locks or standard bolts can be used. 20mm and 25mm are currently available, those that we offer are TUV approved and made in Italy.
