I decided to write this as a seperate post, because it may help someone with similar dilema. I kept my stock sportline springs even though I thought about going for eibach pro kit. I even tried to order them, but my car is superb 3 190tdi 4x4 liftback and the sales guy insisted I should go for the superb 3 combi/ vw touaran spring set ( part no. E10-79-012-04-22 ), even though what I found I should buy is set for superb 3 liftback (part no. E10-85-042-03-22 ). These two kits have the same front springs, but different rear. I listened to my gut and decided to stick with oem height as lowering wasn’t something I wanted, i just thought to give them a try when the whole suspension is already being done, having in mind they aren’t too expensive and may improve handling. What made me get cold feet was I have read about “nose heavy” look that many guys got after instaling the eibach and I really don’t like it. So i did some digging and found out : Stock sportline springs for my car are: Front: 281 mm lenght, 12.5mm wire, 140mm diameter, 4.6 coils Rear: 320mm lenght, 13mm wire, 109mm diameter, 7.8 coils Eibach pro kit: Front spring(same in both kits) F11-85-042-03-FA 248mm lenght, 12.5 wire, 136.5 diameter, 4.75 coild Rear spring in liftback kit F11-15-007-04-HA 303mm lenght, 13.5 wire, 116mm diameter, 8 coils Rear spring in estate/ touaran kit F11-79-008-01-HА 327mm lenght, 13.75 wire, 122mm diameter, 8.2 coils. I put all these in one of those spring rate calculator(i know that isn’t really scientific) but it was interesting. Sportline oem front- 39.02 NM/mm Sportline oem back- 51.74 NM/mm Eibach front- 40.4 NM/mm Eibach liftback rear- 47.89 NM/mm Eibach estate rear- 42.43 NM/mm Rake it with a grain of salt but it does look interesting.

I don’t have side pics of the car right now, I will post them in a few days when i get it cleaned and ready for photoshoot 😄 But it remained pretty much stock, you be the judge when I post pics. I went with bilstein b8 dampers(numbers are in the picture attached to the first post in this thread), did all the “boring stuff” by chasis number (lemforder brand) and I changed out the bushings for audi tts(or s3, I am not sure) but the “almost full rubber” kind, I found part no. here on briskoda. It is 8SO 407 183 B or 5QO 407 183 F, I really am not sure as i sent both to my mechanic who sourced the one which was available, but going by the google pics I think its the latter. Yes, the car is non-dcc. And that b8 damptronic is for the old 997 generation 911 with sport suspension option, which was surprisingly rare, especially having in mind that it meant getting the limited slip diff in the back. Good thing is those dampers for 997 are monotube front and rear. For newer generation porsches(meaning 991 gen. 911 onwards) there is only b6 both for PASM(damptronic) and non-PASM cars, no matter the standard or sport ride height, and they are twin tube in the front and monotube in the rear. For 718 caymans and boxsters they are twin tube allround, i guess its because they have mcpherson struts front and rear meanwhile 911 is mcpherson front and multilink in the back. I dont know if the b16(pss10) for any of those is monotube allround.

Just to come back and write about what i dod to the car in the end. In the end went with bilstein b8 shocks, kept the factory sportline springs and did audi tts bushings. I am blown away how much better the car feels after that, if i had known this i would have done it 5 years ago. Car now feels much more “sophisticated”, it is more compliant, rounds off bumps with ease, there is no more crashing from the suspension and it feels much more controled. I guess the harder bushings also made a steering feel a tiny bit more direct. These dampers are supposed to be “sport” option, but they made car feel better allround and I am more than happy with the results, I just hope they last more than the OEM dampers.

So, continuing my refresh of the 2017 superb sportline 190tdi 4x4, after getting the bilstein shocks I am cinsidering fitting a firmer rear sway bar. But as always, I need to check in with community to see if i am going to get the right thing or mess up… The easiest rear arb I can source is the eibach one for the golf 7r/audi s3 (part number E40-15-021-02-01 ), so the question is will it fit? I know that golf 7r rear arb should fit, but i couldn’t find information about the eibach branded one,I know about h&r one and the whiteline, but I cant get those here. Does fitment depend on the brand or should every golf 7r rear arb fit the awd superb just fine?

I think you are right, b6 and b8 should be 2 identical shocks, aside from the “shaft” (the thin shiny thing 😆) that is 20mm shorter on the b8. I read somewhere that dampers on standard and sportline are the same, but that to me sounds not likely, especialy having in mind that when i previously changed my dampers at the dealership I had to wait for a month for them to arrive because they had none that fit my car available in the country 🫤 Can you help me understand here, how is the compression travel defined by the spring? Isn’t the bump stop the end of the compression travel? And doesn’t the spring dictate ride height and ground clearence? So, lets say that parked superb with B6 damper and standard oem spring has 10cm of compression travel (number is ofcourse imaginery, just for this exhample). Now, if we fit some lets say -30 mm lowering spring, now the B6 damper has 7cm of compression travel before hitting the internal bump stop. The B8 damper has the same body as the B6, just 20mm shorter shaft, so if we fit the same -30mm spring to the B8 equiped car, it should have 9cm of compression travel because the shaft is shorter, therefore the damper is more extended when car is static. Correct me if I’m wrong, as this is why I fear the B6 would bottom out easier on shorter sportline spring(and especialy the pro kit).

Thanks everybody for taking the time to help me. @Carlston Did you mean to write B8 here? Because for eibach they are the clearly recomended option. Thanks for all that info about the sportline springs, i had no idea, and I will continue to call them -15mm now just for sake of discussion. If B8 can work with factory sportline spring thats is rated for -15mm drop form standard that is much more compeling option for me, because in that case I can also order eibach pro kit for my car, try it and if I don’t like it for any reason simply put the oem sportline spring back on the car. I guess after all this time factory springs on my car must have already settled so it is probably atleast half way between “factory new” sportline and eibach pro kit.

But shouldn’t the b8 be clearly better choice if paired with eibach pro kit, or any -20mm or more spring? I ask because as far as i understand the b8 is the exactly the same shock as the b6, just with 20mm shorter “rod”. If we asume that b6 has the lenght that matches the suspension travel of the stock spring, doesnt that mean that if we fit for example 30mm shorter spring the b6 shock has 30mm shorter travel than before, because the rod will hit internal bump stop earlier. If we fit b8 with the same spring 30mm shorter than stock-it has 20mm more room before hitting the internal bump stop, am i right? That is why I am confused should i go with b6 or b8 with stock -15mm spring, because i dont know if those 5 milimeters less in damper lenght can cause wear or damage to the damper, but on compression it should be better because it has more travel, doesn’t it?

Hello, after 8 years and 2 sets of oem dampers(both started leaking) it is time to replace them with something that i actually better than stock. I’ve read few reviews of bilstein B6 shocks on here and I think they are perfect match for my needs, little stiffer and better body control without big compromise on usability. But I have a few questions, as I am not sure what to buy for my car, 2017 skoda superb mk3 2.0 tdi dsg 4x4 sportline(non dcc). As all of you here know, sportline has 15mm lower ride height than standard, so I need to know should i go for B6 or B8. As far as i understand they are the same shock, just that b8 is 20mm shorter. On Bilstein website they say b6 is for oem suspension and b8 is for cars with lowering springs or oem sports suspension(which i have, but it is -15mm, while the b8 shock is 20mm shorter than b6 shock). I found some website that had information about bilstein shocks for superb mk3 and b6 and b8 had same PR codes listed… My car has a G02 code on that little list under VIN in the service manual. Also, my car is 8 years old now and I wonder should i also change factory springs for new ones?
