Front and Rear sponsons for the SX-R are made by Prowatercraft Racing and according to Chris Hagest they make lots of difference to the overall handling of the boat. Hagest shown in the photo- is installing a set of the new long front (cost $365 usd) sponsons on an S4 hull. The rear sponsons will be soon available at the cost of $150usd. Stay tuned and we will soon release a photo of the rear ones.
