Fitting the Schroth Racing Seat

George Richardson, 24 from Manchester UK has been a Schroth UK ambassador for the last 2 seasons whilst at JMW Ferrari and NGK Spark Plugs Racing team. This year fresh off his newly signed agreement. Schroth UK are delighted to follow his career to Walkenhorst BMW where he’ll be competing in the VLN Championship and the Nürburgring 24 Hour in the BMW M6 GT3.

In this interview/ editorial George will discuss how Schroth has helped him in his preparations for the big race and how easy it was to install and fit his new Schroth seat.

Chris Norton and the team at Schroth UK have really helped me in the past few seasons. As a GT Driver I’m jumping from team to team and ‘car to car’ on a regular basis, I always make the seat fit a priority because I’m not that tall! I weigh 63KG and most seats allow me to fatigue really easily because they fit my bum very poorly. Schroth UK has allowed me to think of one thing less when going round the circuit and with their help I actually fit snug in the seat and truly believe I fatigue considerably less than I would if I didn’t have a custom seat.

Driving in 24 Hour races really takes its toll on your body and you have to be reliant on your fitness when asked to double stint, especially at the Nürburgring. For me the BMW Seat was too big and I was moving in pre season testing so much that my core was over working and I was getting tired quickly.

I thought It would be a good idea to note down a few easy steps from my point of view (as a driver) on how easy it is to fit these seats and show others thinking about doing the same that it really only takes 2 hours maximum.

Step 1 – Picking the right seat for you + Unpacking.


Schroth do many different sizes. For the BMW M6 GT3 I needed 25L this is the second one up if you like in terms of volume. For single seat cars and LMP cars the more volume the better if you’re making a full seat but for GT you shouldn’t need more than 30L.

Once you get the seat, make sure you unpack the main bag with the foam balls in it on the floor, ensuring the nozzle is tight and then put the bag in your seat that you want to make a Schroth seat for.

Once it’s in, sit in the seat on top of the bag and get into a position that you are happy with! Then suck the air out of the cap to shrink with your body weight into the seat, keep wriggling to get those last bits of air out.

Step 2 – Get it out, concoct the mix and start to pour.


At this stage you may think it’s done… it’s not!! Make sure the bag is back to being as smoothed out as it possibly can be and get all those little balls equal in the bag back on the floor.

Then make your mix as per the instructions, all you need is tap water, it’s absolutely brilliant, they give you a string stick and you’re good to go.

Funnel the goopy mixture into the bag and move all over your balls so the goop gets evenly spread throughout your balls in the bag. Massage the bag so it’s all even, this is really important.

When pouring the goop in we struggled with the pace it was going in using the funnel, so we just poured straight in from the tub we mixed in, be careful if your doing this as you may end up with goop on your hands or worse the seat. If it all goes in nice you won’t need a new race suit afterwards so if you have a study hand you’re well on your way, if not use the funnel.

Now your seats balls will have turned into a blue colour from white. You now have about 20 mins till it sets so get that bag back into the seat you’rw making it for and carefully sit on it in the position you want it, you can let some air out of the bag with the vacuum at this point should you need to, make sure you manipulate all the balls to the areas you need them.

Step 3 – Wait


Hopefully you are mega comfortable at this point! Ensure you have all the air taken out of the bag with the vacuum. You need to make sure all the air is out and the plastic has started to shrink over the balls in the bag to give a “rough” feel that way you know all the air is out of the bag!

Sit there for at least 20 mins, you don’t want all your hard work to go to waste here so it’s crucial you don’t mess it up, believe me it’s worth it.

Step 4 – Shape up!


When the bag is set and you hop out, take extreme care when taking the new seat out of the seat of your car. Make sure you don’t damage the structure you have built. You will have an exact replica of the bottom of your seat and your backside!

The next thing to do is shave it down a little so you can get in and out of it. Use the sharpest flexi knife you can find to iron out the areas that are going to clamp the Schroth Seat into the existing seat.

For endurance racing you don’t want your new seat to be hard to get in and out, so smooth out for example the hole where the belts are in the bottom right and left of the seat, make sure this is flush.

Then you need to cut space for your groin belt, there is two ways you can go from the side or like we did straight down the middle. Both have pro’s and cons but I went for the traditional way of straight down the middle.

Step 5 – Tape it up.


If you’re in a rush and cannot send it back to Schroth UK to get carpeted then you must use type to type up and create strength in the seat. Make sure you have at least two rolls and a spare hour. Cut the type into foot long sizes and keep typing until the seat is fully covered.

To gain extra strength go over all the edges first then bigger sized bits horizontally across the front and the back, this is really important!!

Finally you are done!

I always put my name on the bottom of the seat in a tyre marking pen so I know it’s mine, sometimes it can be a rush in the garage and the worst thing in the world after all this hard work using this mega product is to get the wrong seat!

Good luck

George Richardson.
