what have some of you guys done to improve your ride quality w/ these springs? it's a little bouncy.eibach dampener's?HAL QA1's?TIA.

Well this is probably not what you're wanting to hear, but most people who choose these springs aren't concerned about handling or ride quality. They're really only good for "the look" or "the stance". They don't leave you enough suspension travel to keep off of the bumpstops and if you try to use shocks that have enough dampening to stay off of the bump stops you've ruined ride quality AND handling. Even Prokits with good shocks (Bilsteins or better ) have tendency to touch down in the rear from time to time. Having said all of this I would recommend a set of Bilsteins ( 3rd gens on the rear ) for a best compromise for you. Actually anything would be better than the stock shocks. You might want to consider using a differant spring if it's really a concern. Sportlines are really to cater to the "looks, first and foremost" crowd. They don't have enough spring rate, nor suspension travel to be good for anything else.

i just got used to it

Small rant:
Dampening = making something slightly wet
Damping = reduce oscillation
Most folks can figure what you mean, but it is still funny to see people talking about making stuff wet.
oh well, carry on.

so what would u recommend to stiffen my car up...and still add Suspension..i don't want my car to hit a bump and look like i got 800lbs in the bag..and it makes it bob up and down for half a mile..i want somethign that is stiff when i hit a bump it don't budge much..sot hat it also gets rid of squeaks in rarttles

would a Bilstein kit be my choise since this is what SLP put on the cars sent off to them?.

For anyone that wants to run sportlines with stock shocks, at least order some new bumpstops from Koni. The OEM one's are just horrible. Not only are they super stiff and make the ride harsh when you hit them, but they also limit the wheel movement. An aftermarket bumpstop like the Koni 40mm or 55mm will allow the wheel to move further up into the wheel well giving you more suspension travel (a very good thing on a lowered car) as well as be more progressive and smoother riding.

thanks a lot bro.now i know that bumpstops are a must.very well written piece.

where do i get these bump-stops?

JasonWW

I called Koni, the stop that comes on the 1139 shock and fits the stock shock is:

# 70.34.54.0000 it is 40mm long - progressive soft and fits a shaft diameter of 16-20mm, it costs $13.57.

They have another one that fits also:
# 70.34.53.0000 it is 55mm long progressive soft and fits a shaft diameter of 16-20mm, it costs $11.22.

This looks like the one to get. It costs less and you can trim it down to the size of the 40mm if you want.

I got the car with sportlines on it already, and im changin them out for the ProKit and revalved blisteins

If you want a better ride then I would remove those springs and replace with another set with a slightly taller ride height and more spring rate. (Along with a better set of shocks)

But if all you want to do is stiffen up your ride (as posted above) then I guess you could install a set of Air-Lift Drag bags (About $60) inside the rear springs and adjust the air pressure to suit your needs. Just a few pounds makes a huge difference in stiffness. Just to warn you though that the ride will still be bumpy if you don't install a premium shock with increased rebound damping. Personally I run Koni Dual Adjustables all around as the stock shocks flat out suck.

thanks for the input guys. i was already looking at HAL adjustable's or koni's. thanks again.

JasonWW

Keep in mind, all you need are the single adjustable Koni's. The double adjustable are not needed unless you are racing. The bilsteins are very good also, especially if you have the fronts revalved to handle the higher spring rates. Those are the main 2 shocks people are using with great success.

Bilstein is making a kit with shocks and springs. Do u know the spring rate or the valveing on the shock?

JasonWW

iTrader: (2)

I don't think Bilstein is making the spring rates known. Maybe someone has heard some new info.

The shocks are just the regular HD's, with no special valving changes.

Try a search for "BTS" for some other threads on it.
