Hallo, hat schonmal einer ein D2 Fahrwerk im Gtr oder Gtx gefahren ?
Wenn ja welches und wie wart ihr zu frieden, und das wichtigste-wie hart sind die ?

Frage nur da es aktuell noch eine Sammelbestellung geben würde und ich evtl. eins kaufen würde...

habs im GTR und kann mich nur anschließen, hart!!

Einfach nur Hart ? Aber wie ist es zu fahren ? Und welchens fährt ihr gibt ja paar ausführungen...

Solch eins hab ich auch gehabt.
Find das es empfehlenswert ist.

Mir hat's nicht getaugt! Im Hari seinem blauen Turbo fand ich's viel zu hart! Hab es auch mit weicher und harter Einstellung Gefahren, war nicht viel Unterschied! Außerdem kommt's mir nicht besonders stabil vor ( sehr zierliche Kolbenstange!) !

Zierliche Kolbenstangen stimmt. Man muss aber den Preis bedenken!

Schau doch mal nach nem BC-Racing da ist die Kolbenstange dicker und so extrem Hart ist's auch nicht.

Ist doch eh alles ausm selben Werk, das mitn der "dicken Kolbenstange" ist die Upsidedown ausführung. Ist also nicht die Kolbenstange sondern das Dämpfergehäuse.

Hauptproblem der Konstuktion ist der geringe Ein- und Ausfederweg. Auch wenn es vom Zug/druckstufen verhälniss auch Schotterfahrwerke gibt ist das ganze System auf rechts gerade Fahrbahnen ausgelegt

Im straßenvehrker tuts so ein billigsdorfer fahrwerk

Obwohl ich auf der straße viel lieber ein serienfahrwerk fahre als so billigteil einzubauen

Im prinzip sind die billigen fahrwerke alle gleich, extrem hart, kaum zu verstellen, wenig federweg und die dämpfer arbeiten nicht so richtig wie es ein gutes fahrwerk tun sollte

JaNe - is klar ;-)

The BR Series Coilovers
Designed for street and trackday
BR Series : Street and Circuit Coilover
BR Series Street and Circuit Coilover

Pillowball upper mount
Camber adjustable top mounts
Aluminium top plates
30 way adjustable damping
Adjustable spring platform
Height adjustment via bottom mount to retain full damper travel
Bearing mounted upper front spring platform
Dust boot to protect damper seals
* some features are dependent on model

The BR series coilovers use a large 46mm diameter piston in a 53mm diameter damper body to maximise oil capacity.

As the damper unit opearates the oil contained within heats up. The viscosity of oil changes as its temperature varies which can lead to changes in the damping characteristic of the unit.

BC Racing only use a very high quality oil with their coilovers but go that extra mile to maximise performance and build their BR range with a large 53mm diameter damper body. This increases the capacity of the unit which increases the volume of oil contained which in turn reduces the peak temperature and so significantly improves damper performance.
Corner weight adjustment:

The lower spring platform of the BC Racing coilovers are adjustable. This allows the car to be set up for corner weighting to achieve perfect balance and ensures that maximum tyre efficiency is achieved.

The car needs to be placing equal weight on each tyre on an axle so both front tyres need to be taking equal loading as do both rears. This makes sure that both tyres are doing their equal share of work when cornering which increases overall grip, maximises corner speed and reduces lap times.

Optional assister springs can be purchased to allow wheel droop to be dialled into the unit to suit specific needs.
BR Series Coilover Ride height adjustment
Ride height adjustment

Ride height is determined by the position of the coilover bottom mount. The mount can be wound up and down the damper body to give a full range of adjustment from near standard ride height to so low it wouldn’t be drivable on the road.

Because ride height is determined by an adjustable bottom mount rather than spring platform you retain full damper travel regardless of the ride height run.
BR Series Coilover Damping adjustment
Damping adjustment:

BR coilovers feature 30 way damping adjustment that combines both rebound and compression in one adjuster for simplicity and ease of use. This adjustable facility allows you to fine tune the vehicle to meet the relevant conditions.

By tweaking front and rear damping you can adjust the way the car handles. Increasing damping force on the rear relative to the front, for example, will start moving the vehicle into a more oversteer orientated stance.

If you want to go drag racing in a rear wheel drive car then you want the back of the car to squat off the line to maximise weight transfer to the rear and therefore onto the rear tyres. This maximises traction and helps prevent wheel spin. To achieve this you would soften the rear dampers to allow faster compression. If you had the rear dampers set to hard, as you might run the car on a race track, then the car would be less inclined to squat so traction would be reduced.

Conversely, if you want to go drifting and are finding it hard to break traction and are having problems with understeer then making the rear dampers harder will help reduce traction whilst making the front dampers softer will give greater front traction. This will make the rear of the car looser whilst minimising understeer thus altering the vehicles handling characteristics more towards drift than drag, road or track.
BR Series Coilover Pillowball (rose joint) upper mount
Pillowball (rose joint) upper mount:

Many of the BC Racing BR coilovers come with pillowball upper mounts. The mount itself is made from aluminium alloy, anodised and then bead blasted to give a high quality, durable finish.

The pillowballs themselves are of Japanese manufacture and their solid nature eliminates any flex or play associated with the standard rubber mounts so improving response and handling.
Camber adjustment:

If its possible to include camber adjustment on your vehicle then the BC Racing coilovers automatically include camber adjustable aluminium pillowball top mounts. These feature the same high quality Japanese manufactured pillowball but give the added benefit of an adjustable top mount that allows camber to be set to suit your needs be it road, track or drift.
Corrosion protection:

The damper units are black chromed steel to give superb durability even through the darkest of European winters. The aluminium components (top mounts, locking collars etc) are anodised and the steel lower mounts go through an electrophoretic disposition process followed by powder coating. A random selection of steel components (brackets, dampers, screws etc) are put through a salt spray test once a month to check the quality of the protective processes and that anti corrosive properties are kept at the highest possible standard.
BR Series Coilover High quality coil springs
High quality coil springs:

BC Racing coilovers only use the highest quality steel for their spring manufacturer. They are produced from SAE9254 high strength durable cold wound steel.

The springs are compression tested through over 500,000 cycles with less that 5% deformation.
Patented concave lower locking collar:

Coilovers use a locking collar to prevent the bottom mount becoming loose. If the bottom mount becomes loose then the damper body can work its way down into the bottom mount so reducing ride height on that one corner which can lead to dangerous handling characteristics. This is a very common problem for coilovers in general. BC Racing utilise an innovative and patented designed lower locking collar with a bevelled edge that seats into a corresponding bevel in the coilover bottom mount. This vastly increases the surface area that the locking collar works on and so prevents the common and dangerous problem of the locking collars working loose.
High quality oil:

BC Racing dampers use a sophisticated shim stack design and high quality oil to consistently control the compression and rebound speed of the damper rod even under the most extreme conditions.

As the vehicles travels over rough ground the compression and rebound motion of the damper rod heats the oil. Poor quality dampers use cheap oil whose characteristics alter with varying temperatures. Its vital that high quality oil is used that can maintain consistent viscosity under a wide temperature operating range. Once the oil start to degrade, its properties change leading to damping changes leading to changes in the vehicles handling characteristics.

BC Racing ensures that only high quality oil is used so that damping rates are maintained not only for the moment in hand (i.e. whilst out for a back road blast on or track) but that long term longevity is maximised with oil that doesn’t degrade quickly over time thus extending the dampers operating life significantly.
Nitrogen pressurised dampers:

When you work a damper hard on track or on high speed bumpy roads you can cause the oil to aerate and cavitation can occour. This causes foaming which effectively reduces the oils viscosity and so reduces the units damping effect. High quality oil goes a long way to help reduce this problem but BC Racing go one step further and pressurise the dampers with nitrogen. The nitrogen exerts a pressure on a floating piston which in turn exerts a permanent pressure on the oil dramatically reducing aeration and so improving the consistency and quality of the damping. The pressurised nitrogen also adds an additional element of effective spring rate to the damper unit.
Bearing mounted upper spring platform:

Because the spring twists as it compresses it is very important to minimise stiction between the spring and its seats. If this tension is not relieved then spring binding can occur leading to the spring rate effectively altering slightly as the spring compresses and extends. The tension generated can lead to rapid deterioration of the spring pearches and in extreme cases can cause the spring platform and locking collars to loosen. This can lead to the platform and locking collars ‘walking’ down the damper resulting in un even ride height and danger of the spring dislocating under full damper extension.

The friction between spring and seats also has an effect on steering effort as the springs are physically turned with the wheels. This introduces additional unnecessary friction into the steering system which has a knock on detrimental effect on the vehicles handling characteristics.

The bearing mounted upper spring platform is one of BC Racings innovative designs. By vastly reducing stiction between the spring and its seats the BC Racing units avoid the above problems thus improving the efficiency of the steering system and allowing the spring and damper to work as designed.

Billig Fahrwerk ist relativ, 800+ Euro will ich jetzt nicht unbedingt als Billig ab tun ;-) Die Herstellung eines KW V3 kostet sicher auch nicht mehr.
Von der Verarbeitung sind die Fahrwerk recht gut, weit besser als Serie.
Verstellbereich von der Dämpferdruckstuffe ist eher zu groß als zu gering, den die kanst das Ventil komplett zu drehen was allerdings zu einen Dämpferschaden führt (ok könnte man als billigkonstruktion ab tun, oder einfach unwissenheit vom Benutzer ^^ )
Die Dämpfertechnik wo hald unterm Gehäuse sitzt ist hald nur wie bei roten Konis nur + Gaspolster.
Ich hab selber ein XYZ und ein K-Soprt Fahrwerk, in den Preisbereich ist es ziemlich das Beste was man bekommt. Vom Besten Fahrwerk trotzdem weit entfernt. In mein GTR habe ich ein Öhlins, da kostet hald die überholung der Dämpfer schon mehr als ein komplettes (made in Taiwan) Fahrwerk, neu.

Na wenn wir schon dabei sind, was für Fahrwerke gibt es den noch offiziel zu kaufen für den GTR ?
Also D2 was noch ? gibt es eigentlich noch Bessere Dämpfer mit Federn ?

D2 / K-sport / XYZ usw. kommt alles aus dem selben Werk, nur andere Verteiber. Daher gibt es die Fahrwerks von jeden Hersteller, allerdings mit verschiedenen Federsetups auf den jeweiligen Dämpfertypen.

Koni - Bilstein - KW bekommst für jedes Auto eine Einzellanfertigung auf Wunsch, aber hald nicht zu den Preis.

Hatte auch mal ein GTS Gewindefahrwerk, waren Kayaba Dämpfer mit 60mm Federn und groben Gewinde ^^
Glaub aber die Firma gibts nicht mehr, und das Fahrwerk war deutlich schlechter als ein K-sport und co.

Koni hat noch rote Dämpfer im Lieferumfang mit Härteverstellung, aber für Serienfedern. Wobei es hier ja auch eine Menge auswahl gibt das die N/mm angeht bei der Anzahl an Lieferanten für Tieferlegungsfedern.
