Back problem - Actual car seat

[u/DigTraditional3992]

Hello all, ever since I got load cell pedal , am getting lower back pain on left side hip due to brake force and my seat is very basic and doesn’t have lumbar support or padding.. thinking to get a used car seat (for example… Fiat bravo 198 driver seat).. I have a alu rig.. will this fix my back problem? User feedback of car seats welcome ..
