Hi, first ever post so apologies if this doesn’t work right...
I’m keen to hear opinions on why oils are increased in weight but not necessarily spring rates. I was thinking springs would provide equal or more resistance/damping (using say 550 oil) without compromising rebound / becoming too slow. Is there a tipping point where higher/lower springs are needed?

Hi guys,
Thanks for the responses. Both answers make sense. Further context: mp9e circa 8.6 pounds. I figured this is about 10 percent higher than nitro equivalent. When I make certain nitro specific changes suggested in previous posts, my car would bottom heavily when dropped at 12inches. I figured oil or springs. Increasing oil worked but it affected rebound as 800 weight is like molasses. I then figured if I increase spring rate 10% this would then make the other suggestions for oil equal between nitro/electric settings.
In summary: use sponge technique as solution to improve rebound. Increase spring to assist additional weight I’m carrying.
The track I’m racing on: smooth, dusty, tight, reasonably big jumps. I’m using grey springs, 8.2 pistons in front, 8.3 in rear. 700 in front 650 in rear.

Sort of but you are thinking correctly. See, let's say we develop an air suspension that is active, that means the load each tire "senses" varies less during driver inputs because the load is transferred slower between sides. With stiffer damping that happens quicker and so happens with stiffer springs, but the springs will have an interesting caveat. The springs always want to retain their normal length, or they wouldn't be springs that means for example during braking the front will resist harder and harder and the rear will jack up! Therefore, when given the choice between harder springs or more damping err on the softer side of springs and go up on damping. Also true for anti squat and kick up, they work like front to rear roll bars.

Finally got my first nitro win yesterday. Car was on rails for the 30min main. I absolutely love this buggy. It drives itself at times. the 2018 season is looking really good What's the deal with the in-line fuel filter? Have guys switched it out for an after market one or stayed with the kit one? I believe I'm getting an air leak at the filter.

no problems with the stock filter here
