Braid has several technical solutions for Formula Student requirements. 

Normally FSAT teams use 13" diameter wheels with width according to the tire selected, usually between 6" and 8". 

In our catalog we have several models, conceptually different. 

The best wheels would be the Formrace model. A wheel manufactured by spinforging technology, radically lightweight, weighing just from 3 kilos, find more information here. Another option is the Splitted 3-Piece wheel, little stronger and heavier than the previous one which is not very common to use in these little formulas, click here for more information. Finally we have the wheel Winrace A and Winrace TCT. These are the heaviest and therefore the economical wheels available, find more information here for Winrace A and here for Winrace TCT. 

The brake caliper determines the inner profile of the rim. If the student has already decided which caliper to use, he must send the interference profile to overhaul with the inner profile of our wheels. For this purpose, either the profile drawing is send by e-mail or the "Scheme 5" available here. Another possibility is to send our inner standard profile and then choose the brake caliper compatible. Apart from the standard profile we can adapt to other specifications, so contacting with our Technical Department is very useful. 

Offset or ET is the distance between mounting face of the wheels to its imaginary centre line. It determines the pathway of the vehicle, which moves the wheel inward or outward. The student must choose their convenience ET or offset depending on the geometry of the suspension used.

 We can adapt to any ET within a wide margin. Contact us. 

The other parameters reported are the number and diameter of the fixing holes implementation (PCD). Information can be found here. If you decide to use Mononut fixing hole, useful information here. 

The last important parameter is the diameter of the hub. This central hole determines the center of the rim to avoid eccentricities. The typical tolerance is 0.1 mm.
