Tested the new Riva sponsons on my Spark -Video and pics
Guy's, I have to admit. I was the biggest skeptic when it came to sponsons on my spark... I really didn't think it needed them. Boy was I wrong. I decided to install the new Riva sponsons and was blown away at how it totally transformed the handling of this ski. Having sponsons has turned this little Spark into a slot car. It will turn as hard as you can possibly hold on.
What's cool about these Riva sponsons is they are actually 7 position adjustable. They have 3 adjustments on the backing plate and 4 adjustments on the sponson blade itself. These are very well constructed with the backing plate being made out of billet aluminum and the sponsons blades a strong polymer with billet inserts for the bolts.
Check out the video overview I did on them to give you a better idea of the construction and adjustment methods
I have plenty of these currently in stock if you want a pair for your own Spark. Use the discount code: greenhulk to save 10% off the listed price.

Looking forward to videos of said slot car
Can they be setup for "loose" handling for spins etc, more that the stock? (I.E go up higher than stock)

When you took the stock bolts off. Did the stock nuts fall inside the hull an have to take the top deck off to get to them?
or are they like the s3 hull just take bolts off an bolt back on?

When I removed mine, I had the deck still on..
Had no issue re-threading into original nuts.

The sponson square nuts are held in place by a plastic housing (sort of like the old X4 pump nuts) so you don't have to take the top deck off.
Just don't torque the hell out of them when you tighten them and you will be fine.

Let's hope the hull stays together ....
