I owned a set of streetlines last year for my 20th, had them set at a slight drop with helper springs and everything else still installed. The ride was bouncy as hell, but they may have needed more time to break in. I think they only had 5k on them.
I have since come across another set of streetlines, and I was thinking of putting them in my Jetta which is supposed to replace my 20th which is now on nice weitec coilovers. The situation is, the black plastic piece that separates the two front springs is missing on one side, which means I need to source another plastic piece or run no helpers. My question is what is the ride like without helpers? I know everyone is going to say "bouncier, what do you think?!" but I would like streetline owners to chime in and tell me their experience. Is it a little stiffer with a mild drop? Or is it just bouncy because people go so low with them? Just trying to get an idea from people's experience, not what someone overheard or read one time. Thanks
FK streetline tend to be bouncy because they are a Damper coupled with a stiff spring. which is why your Weitechs feel so much nicer, essentially the weitechs are a KW V1 without the stainless steel body. (meaning good dampening/ quality valving)
without the plastic between the helper on the FK's you run the risk of having the helper slip off the mainspring or vice versa. i know alot of people who like going extra low and like to take the helper spring out. I don't think your going to get the ride quality you want from the FK's regardless of your setup (helper/ no helper). IMO. good luck. have fun.
you might also want to try to find a slightly softer spring if the ride is extra bouncy.
thanks for the info, that was some good insight. If either way they'll be bouncy, I'll just run them without the helper to save time and $. I have the Weitec rear struts instead of the fk rear struts, but everything else is fk streetline. Maybe the stiffness is because they go so low, so they don't want too much travel? I plan to autocross the car, so would the ride quality suck on bumps but perform well on an autox course because of the stiffness? I need to save up for some konis or h&rs either way I think
Well I have a set of fk streetlines and mine bounces horribly bad ...wtf is with that ? Still has helpers in it too ...

I've had 2 sets of streetlines, both purchases used but in great shape and not much mileage on them. The first set had helpers, the second/current set do not have helpers. Both were bouncy, harsh rides. Streetlines are so stiff, it's crazy. I think it's because they go so low, so they stiffen the spring rates up so you don't bottom out when you're very low. The only good thing I can think about them is they're cheap, better than racelands, and stiff so autocross/track use will be good
