We are particularly proud to have a close relationship with such a world-renowned company such as BBS Motorsport, who has been producing these Caterham Seven wheels exclusively for us since 2011.

Available for all Caterham S3/SV and CSR models in 13" and 15" respectively (Does not fit Seven 160/165 models).

We can also offer the appropriate set of performance tyres as an additional option.

Each BBS wheel offers the following advantages:

  •     Forged, CNC milled wheel centre
  •     Three-piece construction
  •     Optimum radial and axial runout
  •     Possibility of repairing the wheel flanges
  •     Wheel width can be modified
  •     Fastening through light aluminium wheel nuts and 60° cone
  •     Made in Germany!
  •     TÜV registration possible in Rastatt

Should you be interested in running 13" wheels on a standard road-legal CSR, the rear brake caliper must  first be modified. For this purpose, we offer a conversion kit. The common 13" CSR wheel set consists of two 7.0x13" ET 40 front wheels and two 9.0x13" ET 27 rear wheels.

Weights including valve:

  • 7.0x13"ET 40: 4,693 kg
  • 9.0x13" ET 27: 4,883 kg                                    

Road and track day use in combination with tires e.g .:

  • Avon ZZR and ZZS in 185/55R13 and 215/55R13
  • Avon ZZS in 215/55R13 and 245/40R13
  • Toyo Proxes in 185/60R13 and 205/60R13

A significant advantage of the 13 "conversion is not only the improved driveability but also the weight savings. A 15" Caterham wheelset with new ZZS tires weighs about 64 kg.

A 13 "WESMO BBS wheelset with 185/215 tires, however, only around 50 kg! That is around 14 kg unsprung masses! With the combination 215/245, the savings are still around 10 kg.


The combination 7.5 x 13 "+ 9.5 x 13" has been tried and tested hundreds of times for racing with slicks. You can drive all common slicks and rain tires from Formula Renault, Formula 3 and Formula 4 as well as various Avon tires on these wheelsets.

The following wheels are available for CSR in racing and fit under the standard CSR front and rear fenders:


  • 7.0x13 ET 40 
  • 7.5x13 ET 34


  • 9.0x13 ET 27
  • 9.5x13 ET 34
  • 10x13 ET 27
