Seat mounts

[sebackman]

Hi,

The seats in my S3 just sits on the glass fibre floor with the runners attached with 4 bolts. As these cars begin to get older the strength may have been reduced.

How have you reinforced that, if at all?

Larger washers on both sides or added metal plates?

I have searched here but not really found any solutions revealed

Pictures much appreciated.

Kind regards

Stainless 'penny' washers both sides. They need 'forming' to follow the shape of the floor moulding in places.

And don't worry: the seatbelt will hold both you and the seat to the chassis in case of inversion!

I have two metal plates under the floor that connect to the chassis.

I've seen seats torn out of the floor in a collision, and not convinced by the theory that the seat belt alone will hold you in place. As well as being (imo) safer, it also removed a load of flex from the seat which made it easier to feel what the car was doing.

Thank you for the replies.

I need to go under the car to figure out how a support could be done. Do you have any pictures of your final setup?

Kind regards

None to hand. This is actually the second setup. The original one to suit the standard seats used a relatively simple couple of bars clamped between the outrigger brace bars. The current one has some modifications to let me fit a bucket seat.

Are you actually having problems are just seeing this as not very well engineered by TVR?

I agree it does not seem the best engineered job but it has lasted 20 plus years.
Large 'Penny' washers both sides will suffice, doubled up if you feel so inclined.

We have to be honest, if you want to survive to a serious collision, don't drive a TVR car. Sell it and drive a modern car. Do you imagine an Euro NCAP test with a TVR ?

For me, the best airbag and side stiffeners are prudence, anticipation, road analysis and driving skills. And, of course, a well maintained car.
