This is what sets VOLKOV Motors apart.
We don’t build cars purely to produce impressive dyno figures.
We build complete packages where the engine, transmission, suspension, calibration and chassis setup work together.
Every ECU and TCM calibration is developed through thousands of miles of road driving, countless dyno hours and real motorsport competition.
Everything we offer our customers is first tested on our own championship-winning R35 GTR before it becomes part of a VOLKOV package.
VOLKOV Motors now holds every road tyre official Time Attack UK R35 GTR lap record in the UK
That isn’t luck.
It’s years of engineering, testing and continuous development.
We don’t guess.
We don’t copy.
We engineer.
We test.
We improve.
Then we pass that knowledge on to every customer.
Real motorsport experience.
Real engineering.
Real testing.
Real results.
