This has to be the single best mod you can buy to push car to the limit. Droped 5 seconds off lap times at WGI.

 

I agree. The beeper is a great product for tracked cars

 

agreed, one of the best mods for the money. I have LED shifting lights in the car but I still rely on the beeper more to shift.

 

Do the lights and and sound sync up nicely?

 

yes they do, but I perceive the sound more accurately because my eyes are on the road. the lights are peripheral. Pic below of the lap timer, the lights are through the steering wheel so I don't really use them.

 

btw, I connected the lap timer RPM feed from the shift-beeper itself.

 

Yep...I'm a fan. I love that you can set your own tone intervals to compensate for a slight delay in reaction to the long beeeeeeep.
