You Receive exactly what u Pay For

Hey Fellow Subie Drivers i ordered a sparco steering wheel and didn't want a cheapo hub that would in any chance give me hassle. This Hub is spot on no fitment or hassles installing, well constructed. splines line up like OEM. Paired this with a sparco wheel 350mm. im 5'11 long limps, i was unsure if short or standard size would be more ergonomic for driving and this size was perfect. the combination of the two brought the wheel slightly closer and smaller wheel for awesome leg clearance. hope any of this info helps :)

Well made hub that fits perfectly
nursecooper02242 4 years ago
Here is my review of the Splash hub I recently purchased: The Splash hub is made well and fits perfectly on my 92x Aero. The turn signal cancellation works just as it did with the original wheel. Installing this hub does not require any trimming of plastic on the steering column, unlike some other hubs. The only downside for me is that this hub is slightly shorter than the comparable Momo hub. I am changing to an aftermarket wheel so I can have the steering wheel closer to me, to fix this problem I use a Sparco spacer between the hub and steering wheel. Btw the kit comes complete with horn hook-up wire and airbag resistor wire.

Great service and products RSD as usual. Very happy with Splash product very easy to fit and as noted test fitted a Nardi, Momo and Sparco all with no issues and indicator cancellation works perfectly great product highly recommended.

  • Q: distance from column  Cursezzz 1 year ago


    how far from the steering column plastic does this sit off same as stock wheel or more?

    • A: This mounts the same way and position as the stock steering wheel, but it will mount a steering wheel closer to the driver, depending on the dish of the wheel. This hub is approximately 4.5 inches tall.

  • Q: Steering Hub height?  ajc38cu52733 1 year ago


    How much higher will this bring the steering wheel? And what's the height difference between this hub and the short version?

    • A: This hub centers on the spline and will not raise or lower the wheel, but the diameter and depth of the aftemarket wheel can determine position. This wheel is about twice as long as the short version hub.

  • Q: ?  jakerWRX 4 years ago


    what about cruse would it still work?

    • A: This would remove the cruise control fob as its attached to the stock steering wheel. People have relocated them with some custom brackets and wiring. So its possible to still keep cruise control but it would not be connected to the wheel at that point

      Kirill C. 4 years ago
    • A: OMP manufacture a carbon fibre plate that goes between the wheel and hub/boss it may be possible to adapt this for the cruise control,I will be looking into this when I change my wheel.

    Does this hub allow blinker cancellation to still work ?

    • A: Yes the back adapter piece as you can see in the images allows the blinker return to still function like stock

      Kirill C. 5 years ago
    • A: Yes it does, I'm in Oz and I installed this hub on a 06 WRX,it retains the clock spring which is needed for the horn to function and the indicators cancel as they would with the factory wheel.....great product .
