Default Bottoming out problem

I just purchased a 2015 Passat TDI...loving it...but it seems to bottom out in the front...but the shocks seem fine..Im guessing the Passat is a softer ride than my 2011 Jetta TDI...but it seems too mushy....anyone else have this issue???

It says these springs are for mk5/6 wagon, is it the same size as 15 Passat ?

Passat has a mk5 rear suspension so yeah they fit. Toss a mk5 rear sway bar on it too if you want to enjoy corners some more.

Passat went on a huge diet for the NMS vs the euro based B6. Comparing the curb weight of a NMS and a Mk5 jetta, the NMS is only a couple hundred pounds heavier yet has nearly twice the interior size.

I was comparing GSW of the same year and was surprised to see a small weight difference, expected a lot more, which sway bar do you recommend and if there's anything for the front to help with cornering ?

I went to a spring place...they said that they could change all the struts to bilsteins..they are firmer than stock...that would help the bottoming out...good idea?...or should i change the springs as well??

New springs would help prolong the life of your new struts. It would be a wise investment.

It just shows you how much weight/bloat they cut out of the NMS!

GSW isn't the same rear end, its a mk7 on the MQB platform, GSW TDIs have twist beam, not IRS.

MK5 and Mk6 rear ends are pretty much identical seeing MK6 JSW (up until 2014) was just a warmed over mk5.

I went with H&R for their maintenance free quiet bushings, haven't had any issues in the 2 years it's been on.

Had the same bar on my MK5 for 120K and it was silent.

I think the shocks and struts play just as big of a role in bottoming out as the springs do.

While the springs support the weight of the car and a fatigued spring can allow the weight to push down more, the struts and shocks have valves inside which are supposed to dampen quick or heavy movements.

In this case, since the car is a 2015 I highly doubt the springs are that fatigued already. I bet the OP would see a greater difference with swapping out the shocks and struts.

I personally recommend the Koni Special Active (previously called FSD). I have them on my car with the stock springs and the car rides SO MUCH BETTER.

Is there any way to stiffen up the rear on a passat for towing beside new springs ? I only have 25K miles and would like to avoid it if possible, looking to grab 24mm sway bar for better handling at the same time
