Review: UPDATE: I'm downgrading from 3 stars to 1 star. I'd give them zero stars if it were an option. After finally solving a vibration, I discovered these lugnuts are junk. Basically, the conical seat of the lugnuts is not concentric to the threads - which means these lugnuts are incapable of holding a wheel concentric to the hub. This results in vibrations. Here's the longer story for those interested: I ordered a nice set of vintage OZ wheels for my big, vintage Lexus sedan. Mind you, the car rode smoother than silk with its original wheels. Unfortunately, the OZ wheels are rare so I was not able to get them in the exact offset I needed, so I also bought a set of 10mm wheel spacers. I also bought a set of ARP extended wheel studs. When the wheels arrived, I had Discount Tire inspect and spin them to ensure they were nice and straight. They were. I ensured my wheel spacers fit the snout of my hubs just right. They did. I had Michelin Pilot Sports mounted, and fit the wheels to the car. Above 60mph, there was a very obvious vibration. Took the car to the tire shop and they re-checked the wheels/tires - which spun beautifully on the balance machine and were nicely balanced. Next, I thought maybe it was because I didn't use hubrings on the installation. Personally, I think these are usually a gimmick if you have tapered-lug wheels and nuts. A cone has no choice but to fit into another cone concentrically. Five conical lugnuts fitting into 5 conical seats will ensure the wheel is clamped to the hub concentric to the bolt circle of the wheelstuds in the hub....BUT ONLY IF THE CONE OF THE LUGNUTS IS CONCENTRIC TO THE THREADS OF THE LUGNUT! Anyway, I went ahead and bought a set of hubrings to hopefully solve the vibration. Mind you, the OZ wheels have an oddball size hub bore, so I had to custom order the rings. When I installed them, it helped the vibration quite a bit - but did NOT solve it. So I pondered that for awhile when it occurred to me I noticed the lugnuts wobbling as I was running them down onto the wheelstuds - suggesting the outer diameter of the lugnuts was NOT concentric to the inner thread...so maybe the conical taper on the lugnuts was also NOT concentric to the thread - meaning as you torque the nut - it pulls the wheel off-center. So I removed a few of the nuts and mounted them onto an arbor in the chuck of my lathe. I indicated the arbor to ensure it was running true within 0.0005", and mounted the lugnuts onto the arbor - then indicated the conical taper of the lugnuts. I only bothered to measure 3 of the nuts because I was getting readings of over 0.02" run-out. That's absolutely unacceptable. so I ordered a new set of lug nuts, which were more expensive (and much more nicely made) than these Circuit Performance units. I again checked them for run-out before installing and found them to run nice and true. I installed the new, good lugnuts (without hubrings), and VOILA - vibration solved. These Circuit Performance lugnuts cost me dozens of hours of hassle and months of vibrations in my car. They are JUNK. Ok, so here is my original review (when I gave 3 stars), pointing out some of the other issues: Circuit Racing should be absolutely ashamed of themselves for the hex key "tool" they include with this set. It's garbage; it fits the lug nuts sloppy AF. A decent quality 12mm hex key "socket" fits the lugs quite nicely - so I highly, highly recommend you buy one instead of using the included tool. The chrome plating is mediocre. It'll develop rust freckles the first time they get wet. Don't get me wrong, it's better than bare steel or even black oxide - but it's not even as good as the chrome plating on a harbor freight socket. So there's that. Otherwise, they fit, function and torque up just fine. The thread fit was good - I am using these on high quality ARP wheel studs. Review: I've been buying different ones, already bought 3 different ones, finally got the perfect ones. If you have rims with a very tight opening, these are great because they tighten from the top. ## Features - Thread Pitch: 12x1.5 - Color: Chrome - Quantity: 20 Lug Nuts + 1 Tuner Tool - Lug Seating: Tuner Style 60 degree seating - 100% Authentic Circuit Performance Product ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B075TRZBQ4 | | Best Sellers Rank | 611,783 in Automotive ( See Top 100 in Automotive ) 4,060 in Wheel Bolts, Nuts & Studs | | Brand Name | Circuit Performance | | Colour | Chrome | | Customer Reviews | 4.0 4.0 out of 5 stars (60) | | Drive Style | Spline | | Exterior Finish | Aluminum,Chrome,Steel | | Fastener Type | Acorn, Wheel | | Finish Types | Chrome | | Inside Thread Size | M12 x 1.5 | | Item Dimensions | 17.3 x 14.2 x 4.4 centimetres | | Item Weight | 28 Ounces | | Manufacturer | Circuit Performance | | Manufacturer Part Number | CPTUN1215CH-20 | | Material Type | Alloy Steel | | Metal | Alloy Steel, Aluminium | | Number of Pieces | 20 | | Size | 20 Lug Nuts | | Thread Coverage | Fully Threaded | | Thread Size | M 12 | | UPC | 639385691284 | ## Product Details - **Brand:** Circuit Performance - **Colour:** Chrome - **Exterior finish:** Aluminum,Chrome,Steel - **Fastener type:** Acorn, Wheel - **Finish type:** Chrome - **Item dimensions L x W x H:** 17.3 x 14.2 x 4.4 centimetres - **Item weight:** 28 Ounces - **Material:** Alloy Steel - **Metal type:** Alloy Steel, Aluminium - **Thread size:** M 12 ## Images ![Circuit Performance Tuner Key Acorn Lug Nuts Chrome 12x1.5 Forged Steel (20pc + Tool) - Image 1](https://m.media-amazon.com/images/I/61O0j+GFdGL.jpg) ![Circuit Performance Tuner Key Acorn Lug Nuts Chrome 12x1.5 Forged Steel (20pc + Tool) - Image 2](https://m.media-amazon.com/images/I/51bERuBkkVL.jpg) ![Circuit Performance Tuner Key Acorn Lug Nuts Chrome 12x1.5 Forged Steel (20pc + Tool) - Image 3](https://m.media-amazon.com/images/I/51BVTeXd2UL.jpg) ![Circuit Performance Tuner Key Acorn Lug Nuts Chrome 12x1.5 Forged Steel (20pc + Tool) - Image 4](https://m.media-amazon.com/images/I/51WiyGa7QVL.jpg) ![Circuit Performance Tuner Key Acorn Lug Nuts Chrome 12x1.5 Forged Steel (20pc + Tool) - Image 5](https://m.media-amazon.com/images/I/51moOQnKSxL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Is thi compatible with M12x1.50 Hex size 21mm.?** A: I’ll just be honest I didn’t receive the tool that comes with product but the dual fitting should be 19mm and 21mm as a standard. **Q: Those lug nut wont rust inside&outside?** A: Use anti seize or if you're cheap use "clean" axle grease. Torque to specs (actually use a torque wrench). **Q: Will they fit on s 2008 honda accord?** A: The lug nuts will fit the car, but you need to make sure an acorn style lug nut will fit the wheel you are putting on **Q: What is the overall diameter of the nut** A: Regular diameter of any lug nut. However I don't recommend them because the inner cavity the key goes into, stretches and rounds out within 1-2 times of torquing them. I sent these back and just bought some quality gorilla lug nuts ## Customer Reviews ### ⭐ Review *by T***4 on 19 October 2023* UPDATE: I'm downgrading from 3 stars to 1 star.
