Subaru field engineer says OEM wheel studs only good for 75 to 80 wheel changes

And where did you found that Cayman weights 150 lbs more? Cayman is in the range of 3,000 lbs which is roughly +400 lbs. And don't forget, Cayman is a 2-seater. 911 Turbo S is a nice car, but it is far away from the category of BRZ. We should be reasonable when doing comparisons ...

Why is your BRZ so light?

Unfortunately not. I have provided as much detail as I have.

75-80 wheel installations is not a ludicrous lifespan for a economy car, I'm just glad most people strip the threads before they shear the bolts. ARP studs went on my car about 9 months ago after I stripped the OE studs. Makes me feel better that it wasn't operator error, only wish I had kept track of wheel on/offs, I don't think I surpassed 50...

Full tank of gas and all equipment the 86 comes out to 2750 pretty consistently, strip the trunk and run it under a quarter tank and you'll be under 2,700 lbs. One of the few upsides to this car not many people talk about, it really is a lightweight while most cars come out heavier than advertised. I want to say that some manufacturers advertise dry weight, so no oil in the engine, coolant in the radiator, or fuel in the tank so the actual cars come in 100+ lbs heavier than the spec sheet.

I was just confused as to how 3000-2750=400+ lbs, But reading it again i see its +400 not 400+

Generally you get what you pay for, but if the grades are the same, how much difference can there be?

The ARP studs are lengthened - if you need to run spacers, you have the room.

The ARP studs also have a little bit of dead area with no threads at the end of the stud. This little detail makes it almost impossible to cross thread the stud when putting it back on.

Above all realize that if you race your car, studs/lugs are a wear item and should be replaced regularly - even if you've upgraded.

If responsibly done, tire rotations count in there as well, which can be up to 2-3 times per year. Add in one extra for winter rubber (at least in the northern zones) and you have 4 tire changes per year. That means that we will wear out the studs after 18 years--Wait, nevermind, thats totally reasonable.

And he's adding 100lbs to the Cayman.......which also has 50% more HP.

And he completely ignored everything I said regarding build quality. Porsche is at the top of the heap when it comes to any mass-produced vehicle. And bests many of the boutique vehicles.

EDIT: Guess depends on if we are talking about the Cayman or the 718 Cayman. The new Turbo 718s are a touch heavier ~3000 lbs. The 6 cyl cars are ~2900 lbs.

But still 2764 (published base weight) to ~3000 is 236 lbs, not 400.

Exactly, this discussion was pretty much useless. Personally I replied because there was a suspicion in the topic that Subaru is a cheap company. For sure it does not have the glamor of Porsche or other big companies, but it is an earnest car manufacturer. In some cases much more earnest than the bigger guys.

If I got 80 changes, I'd be a super happy man. Instead, I'm waiting until I can install these ARP studs.

The 1st generation Cayman (987c) which was produced till 2013 was heavier. The base car with the 265PS weighted 3,100 lbs. The newer versions are lighter, but also newer designs.

For me quality is a relevant thing. If you mean the leather and the premium feel, then you are right. If you mean not to break, then I insist that Subarus are better.

Do you know who was the chief designer of Porsche all these years? Do you know who designed 911, Cayman, Cayenne? His name was Pinky Lai. He was a designer from China. Try google and you will find a lot about this guy. Do you still believe that Porsche is a real German company?


I will not say anything else because we are already off topic

Our STX car endured 2 full seasons of autocross, changing tires 2-3 times each weekend.

Stock studs, no issues.

I don't even know what to say.

ARP offers an OEM length option now.
