Race Seat Kits, Race Seat Fitting and Expert Technical advice for all Racers.

Schroth iNDi Seat kit uses a vacuum casting bag with a unique bead and slow cure resin mix making it a simple and professional system to fit any driver into any race car. The Schroth iNDi Seat kit gives the user control on where they need to be positioned for optimum performance and safety. Schroth iNDi Seat kit materials have been tested extensively at an FIA Approved Test Laboratory.

With our worldwide name already established in motor racing safety the Schroth iNDi Seat will bring extra benefits to every racing driver in any car. Our reputation is built on quality and unrivalled experience, which we are now proud to say extends to our Schroth iNDi Seat, with our technical support staff having over 18 years experience in making and selling seats in every championship, such as F1, NASCAR, GP2, IRL, BTCC, NHRA, F3, GP3,LMP, World Series by Renault, in fact too many to mention here, but rest assured the Schroth iNDi Seat is Racing’s Best Seat.


For every Schroth iNDi Seat sold we donate to the The Richard Burns Foundation. This foundation was created following the death of Richard Burns, the 2001 world rally champion, from an astrocytoma – a virulent form of brain tumour – in November 2005. It exists to recognise the people who display the same fortitude as Richard during their individual ordeals, giving them the means to face the future with confidence.

How It Works

STEP ONE: Lay the bag onto a flat surface. Form a seat shape. Apply a slight vacuum. Put the bag into the car, get the driver into the car.
STEP TWO: If you have too many beads, remove bag, remove valve and empty beads. Once the driver is happy with the bead volume, driver out and remove bag.
STEP THREE: With the bag removed from the car, remove the valve. Mix resins. Please refer to instructions for resin ratio’s.
STEP FOUR: Pour resins into bag. You will see the resins fall into the bottom of bag. Re – fit valve.

STEP FIVE: Mix the resins and beads together. The beads will change colour when mixed. Will take 5 – 10mins.

STEP SIX: Form a seat shape again. Make sure you have removed creases, front and back.
STEP SEVEN: Put the bag back into the car. Take time to re-position the seat before the driver gets in. Get the driver back in.
STEP EIGHT: Make the seat. You can continue to make adjustments for 60mins from mixing.
