I currently have height adjustable koni yellows with 400lb f and 350lb rear linear Springs. While the ride isn't bad on decent roads, if I make it to downtown Sacramento or some other roads I travel on I start to feel the road more than I'd like.im thinking progressive Springs might help out a bit. I never track the car and it's strictly for cruising.

Edit - currently sitting at 26.25" height. Looking to go to 25.5-25.75"

Any thoughts or recommendations?

 

Ride harshness is much more to do with dampers than springs. My Ohlins DFVs with 13k front and 11kg/mm rear springs rides way wayWAY smooover over bumps and potholes than my previous coils with 9kg/7kg springs. I would sooner get the dampers revalved for reduced high-speed damping if that's an option with the Konis.

 

I plan on buying some ohlins or other highly recommended setups but until I can save up for those I'm just looking at another way to kind of put a band aid on the rougher ride. 400/350 on konis looks similar to what others are using. Can't find any progressive spring info tho....

 

You're probably bottoming out the damper which is why it gets a lot harsher on worse roads. Progressive springs aren't really going to help. That's more or less what you already have when you factor in the bump stops.

You could either get longer softer bump stops or take a gamble and try to get some shorter ones so you never get into them. I don't know how long the stick FD bump stops are.

 

I highly doubt I'm bottoming out on these...

I'm far from being lowered that much.

 

put some zip ties on the damper shafts and find out...

 

I've seen this method used on motorcycles but not cars before. There were sine concerns people had about damaging the suspensions though. Any chance for damaging the suspension on a car with this method?

The rough ride I'm referring to is for the most part at lower speeds through town 15-35 mph usually. I'm guessing the answer at the end of the day is get some expensive suspension

 

I had progressive springs with my Koni shocks, and now have stiffer linear springs with my Ohlins setup. The Ohlins setup feels better on the street, but most likely due to the shocks, not the springs. But, more money... Just some confirmations to what's noted above!

 

I just picked up some aragosta coilovers. I'm not sure if they come with linear or progressive but I've read they come with progressive...

Thanks for the input on the ohlins, I was going to take a look at those as well.
