Default suspension upgrade -- potential problem

I am going to re-do the suspension. Now I am making choices.

This from swedish dynamics:
"A buyer beware: These springs are not for the faint of heart and WILL increase the suspension’s rate by up to 30%…they are not designed for cars with baby seats. Nearly all of our enthusiast oriented customers, however, regard our springs as being quite comfortable without the harsh side effects of some suspension updates."

Query: how severe do these springs need to be such that you can't put a car seat in the car? Are they serious? This is either the damn lawyers again or the ride is way to severe for street driving. BTW - I have two young kids (pre-school age).

I suspect I will go with the Koni. Do these have the same kind of warnings attached?

Any thoughts?

I don't know if SD is kidding or actually covering their legal butts w/ a warning... I would go w/ the Koni spring and damper setup. It's adjustable and MANY say it rides better than stock in comfort and handling. I would love to give my money to a shop like SD. But, I gotta go w/ what I know is good. Keep you and the kids happy go Koni! (That should be a slogan!)

Which springs do this warning refer to? I have ridden in many cars with the Koni set-up and I have Eibach and Bilstein HD's in mine, and I think kids would love it!

I think this is stated in this way because some people do not think the car will have a stiffer suspension when lowering it.

Has anyone tried Kilen springs, which claim to be oem supplier? If this is so and they do not increase the spring rate it may offer the softest ride, but that is an big assumption.

Heard the Eibachs feel great, and H&R sag.

They are letting you know this spring set is for performance and not for comfort and that is the balancing act that the spring companies try and obtain, good solid performance with decent comfort levels. For racing when comfort is not a concern, the spring/damper combinations can be very stiff and ridgid and its the best for performance, but would be hell as a daily driver

It sounds like the sd springs are made with performance in mind more than comfort and this is what they are letting you know up-front. Faint of heart would be someone who wants a better performing spring without the comfort loss, you will have some comfort loss with their springs!

My buddy had these springs with Bilstein shocks and he hit a pothole on a city street and it slamed his head into the roof!!! This is where the baby seat warning comes into play, if you hit a pot-hole or bad bump, speed bumb, it might send you and your baby into the roof liner These are for performance, track type use, not so much on the comfort or daily driver looking for a more comfortable drive to work each day.

I too have heard the Eibach/Koni is the best comfort/performance spring damper combo and next up would be the Eibach/Bilstein combination with a more stiff ride. Next would be something like Intrax springs/bilstein dampers, stiffer yet and then maybe Sweedish Dynamics springs/bilstein dampers.

Its a personal choice as to how performance you want and how much comfort you want. I would put the Eibach/koni at the top of comfort and Intrax or SD at the bottom of comfort, but at the top for performance, body roll, flat cornering and so on... Good Luck, John

thanks for the responses. I assumed that the springs must have been pretty harsh. That said, I just can't imagine they would be so bad you couldn't have seats in the car.
