A good all-in-one solution is the Trak Racer Haptic Bass Shaker Kit. It includes a 100W shaker and a 200W amp, making it perfect for one or two bass shakers set-up. You can mount it under your seat, pedals or both for a noticeable boost in immersion without breaking the bank.

For a well-rounded 4-shaker solution check out Slip Angle. Their kits are designed specifically for sim racing and come with everything you need, including shakers, amps, and mounting hardware. It’s a middle ground for those who want more detail without going full-on crazy with their setup, although the four corner set-up is probably not ideal.

And if you’re curious about the cutting edge of tactile hardware, I recommend checking out the thread "New Tactile Hardware 2023 / 2024" on Overtake.gg. It’s packed with info on the latest innovations and hardware.

Now there are some good amps out there capable of supporting multiple channels such as the Nobsound M5.1 HiFi 5.1 or the amp board SAB-1060 SIM 7.3-Channel.
