Thanks Carlston for brilliant info, looks like some good detective skills! Indeed looks like 3Q0511115AK is the relevant part number when checking with my reg. I am away working at the moment, so will double check with my calipers later. But assuming they are indeed 12.25mm (minus a bit for paint), how can I be sure any new springs would give the same ride quality as the originals? One of the best things about the superb is the relaxed ride quality, is the diameter the only major thing that would affect this? There seems to be multiple brands of springs compatible with 3Q0511115AK --- like KYB, Lesjofors, Sachs, Suplex, Kilen, Bilstein, Triscan, Spidan. They are all roughly similar in price. Just wondering if there is an difference between the brands? I prefer to get a replacement spring with properties closely matching the originals, and fit additional MAD assisters (rather than 1 stiffer spring). That way I always got the option to remove the assister springs and go back to stock setup if I wish. Cheers, Jon

Not sure the part numbers of my springs. But mine is SE trim, 2wd, 1.4TSI ACT, manual.

Hi folks, New here, been meaning to sign up for a while, always looking up topics on here. I have the 2016 Superb Estate MK3. I have owned it for approx 18months. Great car, no big complaints. I have noticed more and more that the rear suspension is quite soft and saggy, even with the lightest of loads. Even a modest tesco shop is enough to create a noticable rear sag. I have measured the height of my wheel arches, the rear is approx 10mm lower than the front when unloaded. However, online I cannot find anywhere the table showing the ride height for the MK3 estate - can anyone share this? I'm considering if replacing the rear springs for some fresh OEM ones would help, or fit some MAD spring assisters, or even both. But first would like how far off the ride height is in order to help judge whats needed. Car is due for service in the summer, so plenty time to figure out whats needed. Fingers crossed the dreaded corona is largely expired by then! Thanks in advance and stay safe! Jon
