here, on frf
i remember back in the day when a few of my friends had rice rockets, some of them cut the springs to lower the car. it rode like shit because it was always bouncing up and down over bumps. drove me nuts.

Thanks for the explanation Krab.

Very true Car Stereo Company...to a very small degree, the pogo hop is somewhat reminding me of a rice rocket or cheaply lowered truck. Guess to that theory...a longer coil spring is needed...Im feeling hopeful that the Gieser Bros spring accomplishes this!

All else equal, a longer spring wire will be a softer spring.
A progressive spring uses a longer spring wire but spaces some coils closer to each other.
As the spring compresses the closer spaces coils will settle on each other effectively shorten the spring wire and the remaining spring will be much stiffer.

@PropDr So are you saying that as the progressive spring settles over time, it will get firmer and possible be firmer than the stock?

or are you just saying as that in a single occurrence...as the shock gets compressed more and more, it will stiffen up?

I was talking about compressing under load, not settling over time and use; but both will have the same effect.
Whenever a coil settles on a other it is taken out of the equation.

Ive thought about it in a single occurrence, it would be a good thing i would think for off roading, you need the suspension firm at a certain point. Ive heard good reviews about the progressive springs during off roading. Supposedly, the tighter, smaller coils towards the bottom, help make on road small bumps and potholes more comfortable...then when you hit a bigger bump (most likely off road) the suspension stiffens. Do you think this is/could be realistically possible?

About the over time settling...I have to admit it does worry me slightly that the smaller tighter springs on the bottom will settle on top of each other and stiffen up. I just like the idea of these springs. And honestly, if they are on bottom perch and are slightly stiffer than the raptors stock bottom perch ride, i don't mind. Im really just looking to get rid of the "pogo" feel over small bumps on road that I'm feeling now on mid perch.

Most springs will settle somewhat during 'brake-in', but a properly designed progressive spring will take this in to account during manufacturing.

Im hoping this is true for these springs. All the feedback that Ive seen is positive! haven't heard anything about any changes in ride over time...so heres to hoping that this is the case!

Does anyone have experience with Gieser bros products? or these springs in particular?

I've only heard great things about Geiser bros quality in everything they do. I know that they do extremely high dollar, real deal trophy trucks.

I might post this on the other thread for these springs and ask people with them.

Thanks for the rundown, I appreciate you sharing your knowledge with me!

Cutting will definitely lower it. Bunch of buddies in college would cut a coil to a coil and a half on their mustangs to get them to have that lowered stance of the Eibach Sportlines or something similar. Don't judge us...we were poor college kits that just had access to a $5 grinder lol. The ride was shit though...very bouncy.

Changing from lower to mid perch should give almost the exact same ride, just a different ride height. There might be a tiny difference due to suspension geometry but I doubt it.

A custom longer spring could give a better ride. I have replacement coil overs from RPG and they claim their spring is more progressive so it's softer on tiny bumps but stiffer as it compresses more. Definitely better offroad and it's slightly softer on tiny bumps but the stock coilovers where super compliant on speed bumps and the RPG are stiff as hell on speed bumps.
