Yes, longer wheel studs are a must option for adding 5-10mm Mazda RX-7 spacers. Many people would like to add spacers to clear big brake calipers. But they don’t want to push the wheels out too much. If you need around 3mm to 12mm wheel spacers, slip-on wheel spacers will do. This type of wheel spacer doesn’t come with pressed-in wheel studs, so you have to replace the stock wheel studs. Tire engineers explain that only if the stud thread is long enough can the studs provide proper clamping force to keep these 5mm Mazda RX-7 spacers and wheels balanced.
It is highly recommended to ensure a minimum of 6 – 8 complete threads of engagement for the lug nuts. For an M12 wheel stud, you would need at least 12mm threads to ensure a safe engagement. Longer studs are available at most auto-parts stores or are included with the purchase of high quality 5mm Mazda RX-7 spacers set. If you’re buying them separately, buy them long enough to compensate for the reduced thread area caused by the spacers you choose. That is to say, if you get a 5-10mm spacer, the new studs should be 5-10mm longer than OEM ones.
Do Mazda RX-7 Spacers Slow You Down?
Lightweight Mazda RX-7 wheel spacers don’t negatively affect the acceleration, mpg, or high-speed performance. People think that spacers make the car slower because of the added weight. However, with the development of modern manufacturing technology, some Mazda RX-7 wheel spacers are made as light as possible while maintaining high strength. The added weight can be negligible. BONOSS forged lightweight plus aluminum RX7 wheel spacers are perfect for performance improvement and appealing look enhancement.
As we know, lighter vehicle weight is better for acceleration. BONOSS forged lightweight plus Mazda RX-7 spacers are machined with “Hollow Carved” holes. The average weight of each BONOSS forged lightweight plus spacer is more than 30% lighter than the previous-gen product. Adding such a small lightweight component wouldn’t noticeably slow a car down. In other words, they will not affect the acceleration significantly. For those who pursue extreme performance, these Mazda RX-7 spacers are a good idea.
Do Mazda RX-7 Spacers Need to Be Hub-centric?
All Mazda RX-7 spacers need to be hub-centric. When installed in the car, the wheel rests on the hub center ring instead of the wheel studs. The vehicle hub ring contributes to the strength of the wheel. With hub-centric RX-7 spacers, they mate the wheels perfectly against the wheel hubs, reducing the chance of vibration. Without such a hub-centric ring, the wheel cannot safely be fastened. So, you need hub-centric Mazda RX-7 spacers to keep the wheels properly secured and balanced.
A good set of Mazda RX-7 spacers are precisely made to fit your sports car. BONOSS forged lightweight plus Mazda RX-7 spacers are designed with better multi-stage hub-centric rings. The multi-layer design provides the bevels to fit the corresponding hub flange, which eliminates any possible gaps. These BONOSS multi-stage hub-centric Mazda RX-7 spacers effectively ensure a firm wheel connection and better load transition. The wheels are well-balanced so that there will be less chance of vibrations.
