på bilen?
Amazon senket 30 mm når jeg kjører over fartdumper så
går demperen helt i bunn

Då behöver du nog framförallt hårdare fjädrar! Har du bara kapat originalfjädrarna?
Koni gör för övrigt bra dämpare!

Är det de gamla dämparna som satt på innan du monterade sänkfjädrarna, så kommer de att få jobba utanför sitt gamla arbetsområde och kan följaktligen vara helt odugliga. (Cykelpumpar.) Gasdämpare rekommenderas även om de är lite dyrare.
Det är alltid bra väder när man amazonar.

Jag vill nog fortfarande hävda att man ska ha hårdare fjädrar om fjädringen bottnar.
Du bör naturligtvis anpassa dämparna till fjädern men det är inte dämparen som ska sköta jobbet!

Koni röda är bra och prisvärda dämpare. Köper du dem av en seriös handlare kan du få dem kalibrerade efter dina fjädrar för en relativt rimlig peng.

her er noen gode råd fra Developments. bilsteins støtdempere selges i satser på ebay for 299usd = 1327,56 nok for alle fire eller 125usd =555 nok for de bakre + frakt og moms selvfølgelig :wink:

Suspension Springs
Shock Absorbers
Sway Bars
Suspension Bushings
Volvo was slow to make the transition to modern handling. Vintage Volvos with stock suspensions are typically too high off the ground and have excessive roll in the corners. Our suspension components are designed to bring modern handling to older Volvos and are a necessary part of any performance package. Progressive rate suspension springs are a significant advancement over other spring sets offered. Combined with appropriate lowering of the vehicle, attention to suspension bushings, shock absorbers, and sway bars where necessary, the handling of an older Volvo can truly be transformed.


Suspension Springs
Springs are the heart of any suspension. Most aftermarket suppliers only offer one replacement spring, usually 20% stiffer - designed for a one inch lower ride height than stock. These are the same springs that have been offered for over 30 years, and they still have the same problem they have had since the beginning. Quoting Volvo's own R-Sport Performance Parts Catalog, "The shorter and more stiff the spring, the worse the ride becomes." Volvo recognized that the problem could be solved with progressive rate springs. We still offer those traditional performance springs, but in addition offer an entire range of springs in different heights and rates to fit individual needs. This will allow you to tailor the handling to your driving style and intended use of the vehicle.

Progressive Rate Springs
Although single rate springs offer improved handling, they do so at a price. A stiffer spring improves cornering ability, but the ride is stiffer, sometimes to the extent of an unacceptably harsh ride. In the past you had to compromise and ended up with a spring that was not stiff enough to improve cornering as much as was desired, but still gave a harsher than stock ride on the street. Progressive rate springs overcome this problem. With these springs, to quote the R-Sport Catalog, "...the rate or stiffness of the spring progressively increases as the spring is compressed... This results in a relatively comfortable ride during normal driving but provides the necessary stiffness for large bumps and hard cornering." For this reason most of the springs offered in Volvo's R-Sport Catalog were progressive rate springs.

While our progressive rate springs are not exactly the same as those that were offered by Volvo, the principle is the same. The initial coils are as soft or softer than stock and absorb minor bumps such as highway expansion joints. After a small deflection the stiffer coils come into play and control roll in cornering. Because there are also softer coils, the stiffer coils can be of a higher rate than would be acceptable in a single rate spring for street use. Thus the handling improvement is greater than what would normally be possible with a single rate performance spring.

Feedback from those that have tried the progressive springs has confirmed that they offer great handling with a better than stock ride. Most can't believe the difference.

Our testing has shown that progressive rate springs are not necessary in the rear and can create other problems, so our 4-spring sets consist of progressive rate fronts matched with single rate rear springs.

These spring sets were developed and tested on cars with stock front sway bars. Testing showed that sufficient control of body roll for most street applications was achieved through the installation of these spring sets with appropriate shock absorbers, without adding stiffer sway bars. Not having to make to spend an additional amount on sway bars can obviously result in considerable savings.

Although most spring sets will lower the ride height between 1 and 1-1/2 inches, we have developed several different progressive spring set combinations. These will accommodate different models, vehicle weights, and customer preferences as to ride heights and type of use, and include front springs of approximately stock ride height. Combined with the use of spring spacers (shims), they allow ride heights to be adjusted to individual tastes.

Progressive rate springs are slightly more expensive than single rate springs, approx. $20 more per pair, but are well worth the difference. Most springs come with a blue powder coating. Full sets for the 140 and 164 are now available (pictured above). Call, write, or e-mail for details on the appropriate progressive rate spring set for your application.

Single Rate Street Springs
Where our progressive rate spring sets will not meet a particular need we offer single rate springs that are stiffer and shorter than stock for the front and rear. Street performance springs are usually selected to lower the car from one to two inches. (How much the car can or should be lowered is dependent on the wheel and tire combination used, the ground clearance necessary, and the need for sufficient suspension travel.) They significantly reduce body roll and give a stiffer ride. Some spring combinations may require modified mounts.

Competition and Race Springs
Offered in custom heights, rates for competition use normally start at 700 lb front, 180 lb rear and go up from there. Most road racers use 800-1000 lb front and 175-225 lb rear in the 1800. Some rear springs require modified spring perches or spacers. Adjustable height spring perches are also available. E-mail your individual requirements and I will try to make a recommendation as to which springs would be best for your car.

Spring Spacers
We offer spacers for the front of the 1800, 122, and 140 in stock 1/2 and 1/4 inch sizes as well as custom spacers in all sizes. Using spacers allows you to make small adjustments in ride height to suit your individual preference or to provide clearance for different tire and wheel combinations. In the front the ride height change will be double the spacer thickness. In the rear the change is the same as the thickness of the spacer. The 1/2 inch spacers are $15 a pair and the 1/4 inch spacers are $12 a pair. Rear spacers are matched to individual springs and are currently machined to custom specifications.

Adjustable Spring Height Adjusters
To meet advanced needs we have developed both front and rear spring height adjusters. Some simply slip in with the springs, others must be welded to the chassis. As there are a number of different types depending on the application, please e-mail for details.


Shock Absorbers
We offer several different types of performance shock absorbers for street and racing use. Shock brands include Bilsteins, Konis, and Carreras. Whatever brand of shock you choose, it is crucial that the shocks be compatible with the rest of your suspension. In general, a shock with stiffer valving is needed with stiffer springs.

Bilsteins have been the shock of choice for vintage Volvos for many years and deserve their excellent reputation. A sophisticated design allows them to provide outstanding handling performance and an exceptional ride. They seem to last forever. Not all shocks can be used on lowered cars, but this is no problem for Bilsteins. They are a good shock for use with the progressive spring sets described above, but may not be the best choice for the rear of lighter cars, especially with stock rear springs and bushings, because of the stiffer rebound valving in the rear shocks. We stock Bilsteins for 122s and 1800s, and can order them for 544s, 140s and 164s.

Before Bilsteins, Koni shocks were the standard. After an absence of more than a decade, the classic adjustable Koni shock is back and is available for 122s and 1800s. Although not as technically advanced as the Bilstein (the idea was to bring back the original classic Koni for vintage cars, not update it), it has the advantage of being adjustable to meet your individual needs or compensate for eventual wear. Like the Bilsteins, these shocks seem to last forever, and are an item that you keep and transfer from car to car. The set on one of my street 1800s is now on its third car and they still feel like new.
