Formula Student Carbon Rim

Blackwave offers a lightweight and reliable „plug and play“ carbon rim system for Formula Student teams. The „Formula Student carbon rim bed“ is designed for racing purposes and has a great price-performance ratio. The rim is optimized to meet FS competition-relevant criteria.
During their time at Formula Student, the founders of Blackwave wanted to apply the carbon-SMC process, which they had worked with during their time at Airbus. As a result, the first carbon SMC rim was developed and successfully used in 8 competitions. After 3 years of continuous development, the rim can now be offered to other Formula Student teams.

Bjork van der Donk, Powertrain & Suspension Manager, URE11, University Racing Eindhoven:
“During the Formula Student Germany (FSG) 2015 edition, we came in contact with Blackwave. We knew that a staggering 4 kg on the total car could be saved if we switch to carbon fiber rims. Eventually we decided to use the C-SMC rims on the all new URE11. In combination with the new final drive, a total 12 kg was saved on the car!
In the end we are glad upon the decision of using the Blackwave C-SMC rims. It saves a lot of weight on our car and fits our custom Apollo tires in a better way than our previous aluminum rims. As the rims came in sealed perfectly, we did not encounter any leaks at all, not even after a full event at Formula Student United Kingdom (FSUK).”



The rims are designed for 10’’ tires. The tire should only be fitted when rim is fully assembled and tightened with screws. We strongly recommend that the mounting of the tire is performed by authorized and trained specialists and with the appropriate machinery. To prevent damage of the rim flanges, use plastic protectors. After mounting the tire, the wheel should be balanced.

Air tightness

The air tightness of the shells is ensured for demanding racing applications.

Delivery time

The delivery time is 4 weeks.

Additional fees

If delivery is made to a non-EU country, additional taxes, duties or fees may be charged to your order that are not included in our invoice but are payable directly to local customs or tax authorities. For details please contact these authorities.
