How To Drop Sponsons
I have an 04 RXP on which I want to install 05 stock sponsons for racing Supercourse. I know the best set up is to drop the sponson level to the hull line. I can handle any mechanical mods, but body/hull work is not my specialty. Can anyone post a "how-to" and maybe some pics to help me with this project?

Measure the distance from the bottom most part of the sponson, which is near the front of it, down to where it JUST starts to curve under....that distance is how far you should relocate the new mounting holes LOWER than the current ones...REMEMBER, the front mounting hole is 1/4 lower than the other 4...AND on the 04 unit, the mounting holes are smaller than the 05-up unit, so drill accordingly...

its quite a big job as all the water box and everything down there has to come out so you dont drill through it .
remove your stock sponsons and make a template
usually you drop them 24mm so they dont pertrude your hull at the back
then line up all the holes and drill
bolt your sponsons back on and mastic
this is quite brief sure someone else will post pics

Just make sure you don't put any cheap, sorry, home made jobs on there.
