Ok, I've done a lot of searching and yes, there is tons of random info on the forum about the koni red shocks and FFR standard springs (#500F/#300R), but I don't really see much out there about fine tuning or making adjustments other than 'put the setting to softest' and that's about it.
I find the ride very bouncy, the car feels unsettled going over even moderate bumps at 30-40mph. I've driven light cars before so it's not just it being different than a 'normal' or modern car. It certainly handles like a go kart, which is great...but it almost feels nervous and jittery in a bad way, not really planted and secure. My car is 100% completed mechanically, body on, shocks double checked to be in softest position, alignment done to recommended specs, and no sway bars attached. Ride height is right around 4.5" front, 5.25" rear. Riding on 15" wheels (maybe that's part of the problem!), tire pressure around 25psi.
My first thought is to increase the damping on the shocks to reduce the 'bounce', which feels like too much rebound after initial compression. If this is a common experience with this car I expected to see a lot more threads about how builders are finding it better to firm up the shocks or make adjustments other than what we are told to set things to initially, but I'm not.
I know this is just the beginning of getting the car sorted out. It's going to take time and part of the decisions made are personal preference, but I was wondering if anyone had experience with these stock spring rates and shocks who could give some pointers or share what's worked best for you after you made adjustments after initial setup. I refuse to believe everyone is just sticking with the initial settings and not making any changes.
Firming up the shocks is my next step, I think...will see what happens from there. I do believe this is a decent enough chassis to be able to handle well with the right adjustments and parts. Would love to hear from some of you who have experience with this.
Whether it be improving ride quality or setting your car up for autocross or track...let me hear what's worked for you!
