BMW 3 Series race
August 3rd 2025, Castle Combe
To celebrate 50 years of the BMW 3 Series, the CSCC are holding a stand-alone race for any age BMW 3 Series or BMW 4 Series.
Any tyre, any engine, any gearbox, with classes designed to give 3 Series of any performance, a chance of an award.
See below for further details.
Entry Details: Entries will open in May 2025, on a 1st-come, 1st-served basis.
Entries can either be for a single driver, or two drivers sharing a car.
Qualifying is 18 minutes in length, all drivers must complete a minimum of 3 laps. This is short, but a typical lap time is likely to be in the 1 minute 10/25 second region, so plenty of time to get those laps in, even for two drivers.
The race is 33 minutes in length, with a mandatory 90 second pit-stop, measured from pit in to pit out, as per CSCC regulations.
The pit window opens at 10 minutes and closes at 23 minutes.
If only entering this race, the entry fee is £300.
If you also take part in another race during this meeting at full price, you pay just £133 for this 3 Series race.
All drivers must be a member of the CSCC and therefore agree to our closely controlled driving standards. Membership is £49 and will last for 12 months.
There will be a lunch time grid walk, where spectators get to see the cars up close.
