Yamaha what rate spring you running in the rear?

[BrianAshby1]

Ok I just want to see what everyone is running on the rear of the car as far as spring rate weight.

2 seat is what im interested in

We have a two seat teryx with a +3 long travel and baja cage with a spare tire rack, our rear springs on our elkas are 450 lb. They run great!!

There are spring rate calculators on the internet if you know the weight of your vehicle. Court and I have been testing some different shim stacks and spring rates on his race car and we are down wayyy low on the rear spring rate right now...

just getting a little ass end buckin going on when the whoops are LOOONNGGG whoops and i cant make enough speed to stay on top of them...

i'll try to find a video to illustrate whats going on

not sure of the weight of my car, its a two seater with a beefy as cage (might be some weight there) and im running kings with 350lbs in the rear

first time trying a video... does this work?

300lbs on my ride

Seems thereis no way to compare one kit to another as the shock angles will be different. I ended up with 300 preloaded 1/2" driver side, 275 no preload pass side rear. When I sit in the car there is 200lbs more weight on the driver rear tire than the pass. I used FOA shocks spring calculator. It only calculates for sag, and there is a lot more than sag that should determine the spring weights, but it's a decent start point.

i think a 275 or 300 would work best. it depends on your valveing and also how you aproach the whoops as far as what speed your at.when your going down hill yourback will kick a little more naturally. what spring are you running in the front?

 

[roostingrhino]

i have king 350's pn rear and i also had a hop thats simular to that... what would be the direction to go on valving?

 

[speedracer]

im not shure but i would try the spring first. if you have the stock bed in the back and its only a 2 seater the you might go with a 300 in the rear and a 250 in the front. check out the video of me on my dads stock 450 with a plus six a arms and bilstein shocks. i have that same combo on the springs but my race rhino has the same kit with a 225 front and a 250 rear. check out the video at you tube under jumping rhino.mod
