Thank you
Jim thanks for explaining this to me and in detail too, all good for us newbies to know:thumbup:Darren,
The 2015 F3 rear shock has a 360# too weak spring & not stiff enough dampening on stock rear shock, so it totally bottoms out with rear shock compressing until end of shock travel is a solid hit, putting tremendous stress on 2015 F3 rear frame subsection that BRP has acknowledged cracks the rear frame area!!
I have an Elka stage 2 rear shock with a 800# Eibach spring (8" long x 2 1/4" ID) that lifts rear to normal ride height even with 2 up riding!!
So you can see the stock rear BRP F3 shock spring is way too soft for even the driver in normal riding.
The 2 up 2015 F3 BRP shock replacement with a little stiffer spring probably works ok for driver only.
But I would suggest using that $200 toward buying a Elka stage 2 rear shock with a much stronger spring/dampening set up for your riding style!!
The 2016 F3T & Limited solved the rear shock bottoming by installing a rear RT air dampener that you can adjust the air pressure to lift up rear for a stiffer ride for 2 up riding.
Hope this explains rear shock bottoming for you: bottoming is NOT good.
Enjoy.
Jim
