034 Motorsport - Density Line Bump Stops, Rear, 81mm - Audi B9/C8 Chassis - 034-403-Z002.

034Motorsport Density Line Bump Stops are engineered to solve one of the biggest drawbacks of lowering a vehicle: reduced suspension travel. When travel disappears, so do handling precision, ride comfort, and the ability for the suspension to keep the tires planted. Density Line Bump Stops are specifically designed to restore this lost performance while adding tuned, progressive control that factory or cut bump stops simply cannot provide.

034Motorsport Density Line Bump Stops

Engineered Travel. Tuned Control. Superior Comfort:

034Motorsport Density Line Bump Stops are built to address one of the most common issues that comes with lowering a vehicle: the loss of usable suspension travel. When the suspension runs out of room to move, the car's ability to handle precisely, ride comfortably, and maintain consistent tire contact all start to suffer. These bump stops are specifically designed to restore that performance by providing additional, carefully tuned suspension support. Their progressive characteristics manage impact forces smoothly, offering control and protection that factory or trimmed bump stops simply cannot deliver. The result is a more composed, predictable, and confident driving experience, especially on lowered setups that demand proper suspension geometry and travel management.

Why Suspension Travel Matters:

Lowered vehicles lose valuable suspension travel, which causes the suspension to reach the factory bump stop much sooner than intended. A bump stop is designed by the OEM as a final-stage buffer, essentially a rubber cushion that protects the shock and suspension components from bottoming out during extreme compression. In a stock-height vehicle, it is meant to engage only during hard impacts and serves as a safety and comfort device rather than a primary spring.

When the vehicle is lowered, that engineered clearance is reduced or eliminated. As a result, the shock engages the OEM bump stop far more often and under lighter loads than originally intended. This turns the bump stop into an unintended secondary spring, which restricts suspension movement, reduces the suspension's ability to absorb bumps, and prevents the tire from maintaining a consistent load. The outcome is a noticeable loss of ride quality, grip, and handling precision.

Lowered on OEM Bump Stops

  • The suspension stops absorbing bumps
  • The tire loses consistent load and grip
  • Handling becomes unpredictable
  • Ride quality becomes harsh and abrupt

Factory bump stops were never engineered for lowered ride heights, and cutting them only amplifies harshness.

Lowered on Density Line Bump Stops

  • Restores usable shock travel on lowered vehicles
  • Keeps the suspension operating in its intended range
  • Improves chassis balance and stability
  • Enhances comfort by allowing the shock, not the bump stop, to manage impacts

Result: A poised, controlled suspension that maintains grip and comfort instead of bottoming out.

Precision€‘Tuned Compression Rate:

Factory bump stops are designed for stock ride heights and spring rates, which means they often fall short when a vehicle is lowered. 034Motorsport Density Line Bump Stops are specifically engineered for lowered setups, particularly those running Dynamic+ Lowering Springs. Each bump stop is carefully shaped, sized, and density€‘matched to provide a progressive compression profile that acts like a miniature spring and damper. This allows for smooth, comfortable early travel while increasing firmness as the suspension approaches full compression. The result is controlled body motion, predictable handling, and improved ride quality without harshness.

Platform€‘Specific Engineering

Every Density Line Bump Stop is designed to match its specific chassis, ensuring optimal suspension performance. By utilizing vehicle-specific shapes and lengths, these bump stops restore suspension geometry and travel to near-factory levels, even after lowering. Their compression rate and progression are tuned to complement Dynamic+ Lowering Springs, maintaining handling balance while providing consistent, predictable performance. The optimized length and compression characteristics ensure the bump stop works seamlessly with the rest of the suspension, completing a fully engineered performance package rather than serving as a generic replacement.

Why Not Just Cut the Factory Bump Stop?

Cutting factory bump stops might seem like an easy fix, and people have been doing it for years. But every shortcut has a cost. Trimming might buy you a little travel, but it ruins the last phase of the carefully tuned suspension travel that keeps your suspension controlled and your ride composed. The result? Harsh bottom-outs, unpredictable handling, and a setup that never feels quite right.

034Motorsport Density Line Bump Stops are the right way to do it. Designed from the ground up for lowered vehicles, they deliver the full range of motion your suspension deserves, with smooth, progressive control that cut OEM stops simply can't match. More travel, more precision, no compromises.

Very gentle, lightweight, absorbs well without feeling greasy or heavy. Perfect to use after Fraxel laser treatment. I also like it is fragrance free and really good on sensitive skin.

Medium weight minimal ingredient moisturizer!
Size: 3 Fl Oz (Pack of 1)
As with another review, I’m looking for a replacement/dupe for Eucerin Urea Repair face moisturizer which is 5% urea Skin concerns: dry rosacea, mid-40s, arid climate with 4 seasons, winters are cold and snowy and summers are 90°+ for most. This is a medium-weight moisturizer that I consider not greasy at all. It is not as hydrating as I need it to be for my dry skin type with rosacea. Thickness wise I say it is similar to a standard facial sunscreen. It does last overnight, in the morning I can still feel it in some areas. I will try increasing how much I apply in order to see if it helps with how much staying power it has. This may increase the hydration it provides and I will update my review to report back. I had a very mild stinging sensation but my rosacea is struggling since moving to a dry climate. Once I repair my skin barrier a bit, I fully expect this will cease. Due to this, I’m not going to get my husband to try it, he has constantly broken skin from severe eczema and stinging is something that makes him not use moisturizers. It’s a battle! For people in more humid climates this may be a more effective moisturizer, or those with less-dry skin than me. I never have flakes so this wasn’t a parameter for me. There is no tint. I’m not sure about white cast so I can’t rate it for skin tone. But I don’t feel there would be, this seems translucent unless you really go in with it. For me it is reasonably effective. It’s probably a good day moisturizer and I expect it plays well with sunscreen, though I would definitely let it absorb or dry down. Which is pretty standard for daytime skin care. There is a slight grippy feeling when applying, but this dissipates like the Eucerin Urea Repair does. This is not, for me, a replacement or dupe for Eucerin Urea Repair. It is a great value for the price! Overall for someone with skin like mine I rate it a very solid 4/5. I would likely purchase again for a lightweight moisturizer as a more affordable substitute for Beauty Of Joseon Dynasty Cream for day. Though this does not give me the “bounce” that does. Alas. Updated to add: I tried increasing the amount I apply, and that eliminated any grippy feeling when applying. I now apply both day and night and this has helped repair my barrier enough it doesn’t sting when I apply this. I still have a way to go before I can return to using my sunscreen, but I do work in a building with no windows so the few minutes I am outside, it’s okay if I go without. If I apply this to my eyes, it doesn’t sting them, which is great, my eyes are extremely sensitive and I hesitated, but it works out just fine. It isn’t thick enough to cause whiteheads to form on my lids, unlike some balm-type moisturizers (LRP!) and even unfortunately Bioderma Sensibio Eye+ I have noticed the backs of my hands are improved as I wipe off excess onto the backs of my hands and into my cuticles. I was genuinely surprised by this, it’s not like I don’t wash my hands. I wasn’t expecting it to have any effect, but the stinging scaley hands are gone, now my hands just feel normal, even after wearing wool fingerless gloves all day at work. I will continue to use this product and will repurchase even after my financial situation improves.

My rosacea approves
Size: 3 Fl Oz (Pack of 1)
I have Rosacea, dry, sensitive, reactive skin and perimenopausal skin. My rosacea products tends to dry my already dry skin and this has been been a great moisturizer. My skin looks dewy, dullness and dryness have improved in just 2 days; I haven't reacted with sting and redness like I usually do and when I wake up I still have a dewy not greasy face even though I sleep on my sides and toss and turn all night. Definitely going to buy again since the bottle size is good, a lil goes a long way and does not make my face react like the CeraVe.

This stuff works nicely
Size: 3 Fl Oz (Pack of 1)
So I don't typically leave reviews, but I feel like this lotion has been fantastic to me. I typically don't use lotion because I hate the feel, but my face really needed it. I have dry/oily skin. My skin gets gross and flaky, yet it's pretty oily. I've always dealt with it. I decided to go ahead and buy this stuff because I couldn't take my dry skin. It helps soooo much and you barely need any. I use a dime sized amount and really focus on my problem areas. It lasts all day, not too thick and not too watery. Not greasy at all for me and soaks in very nicely. Again, it lasts all day and I don't need touch ups, even on bad skin days. I don't ever break out and it's never clogged my pores, but to be fair I've never really had skin that's broken out much before. The one thing I did notice, before using this stuff I started noticing more fine lines around my eyes/forehead. I've been using this stuff for about a year and you can barely see them anymore. I have haven't changed my diet, it's pretty atrocious honestly, so I really feel this lotion has worked wonders on its own. Also I still have a decent amount left in the bottle and I bought it almost a year ago. I'm going to try their body lotion next. Hope this helps, or at least give it a whirl!

Excellent for hydrating & moisturizing super gentle
Size: 3 Fl Oz (Pack of 1)
I really am quite amazed by this product. I’ve been using top anti aging skincare from a very prestigious, high-end brand for a long time. I’m amazed at how inexpensive this product is and how lightweight, gentle and moisturizing it as. I’m really happy I found it. It’s really incredible for hydrating and skin that is very well hydrated looks act younger. My prior anti-aging moisturizer just never moisturized THIS well. Unbelievable . My skin looks younger .
