Dms Adjust. Coilover Shocks For Gtr R33 Or R34

[gtrracer]

DMS Drummond Motor Sport 50 mm Coil Over Shocks and Springs.

Set of 4 to suit R33 GTR and R34 GTR

Comes with instruction manual and adjusting tool.

These have both independently adjustable bump and rebound.

Also these are on top of the shock so they are really easy to adjust.

You don’t see these babies up for sale very often because everyone who’s got them loves them.

These are the Tarmac Rally version. Not the street version.

That is they are the high performance version in 50 mm not 40mm.

These are our “spare” set and only have done low kms.

These are tuned for Tarmac Rallying but are an awesome street setup with a great ride.

These have progressive springs that give you a nice ride (but very “sporty”) around the street and awesome traction both wet and dry, but as you begin to push the car the spring rate rises meaning that it soaks up large or high speed bumps as well.

Please remeber these are twin progessive rate springs so you can't directly compare to linear spring rates.

Fronts are 700 lb with 250mm free length.

Rears are 400 lb with 350 mm free length.

These are great for street and competition and would only need different springs for really hardcore circuit racing on really smooth circuits.

These are in fine working order and low kms and I will sell these for $2,600.00

PLEASE PM me as I don't get a lot of time to check the forum.

DMS shocks are incredibly well built but if you need they can be fully rebuilt and services in NSW.

The following information is from DMS promotional literature:

Every DMS suspension contains a number of special features which set it aside from the competition.

The technology behind DMS products was not merely influenced by a race proven design, but rather has become a race proven design.

DMS Springs:

All DMS products come with the same design philosophy: The best performance in all conditions, configurations and driving styles possible. DMS suspension units use a specially designed spring that is matched with the tune of the DMS shock absorber for race, rally or high performance driving.

These springs cannot be constructed in a conventional method and require several specialised procedures in manufacturing. Incorporating within one unit a taper wire and taper wind design, there is no "dead spot" where the tender spring and linear spring would meet. This results in uniform compression and rebound rate that provides maximum suspension travel for best grip and traction, as well as having a strong spring rate necessary for motor sport or performance driving. DMS springs are tested and proven in competition.

50mm Adjustable Shock Absorber:

DMS first designed and manufactured the 50mm suspension system in 1990. Testing and tuning has continued and now has produced DMS's most successful product - the two-way adjustable damping shock absorber. This adjustable shock absorber has been used in production car motor sports.

This DMS high performance 50mm shock absorber has one of the largest pistons available in a shock absorber in the world. This gives superior control, more precise tuning due to larger displacement and pressure areas and precise adjustment on bump and rebound independently.

The larger the piston area the lower the internal operating pressures and temperatures. This provides higher damping capabilities which are necessary in severe rally or race competition. Compared to conventional shock absorbers the DMS Giant 50mm has over 200% improved accuracy and control.

Product Description:

DMS blue shell case. Made of chrome-moly high strength steel. Threaded and Fitted with screw- adjustable anodised aluminium spring seat and lock nut.

Competition specification mounting brackets.

50mm shock absorber system with high flow competition design piston with defined adjustable bump and rebound settings. DMS only use special formulated racing shock absorber fluid.

spring rates please.

[gtrracer]

spring rates please.

I will check them but I won't be back on the forum until Monday.

As these are progressive you can't compare the rate to linear spring rates.

Why do you want to know the rates? Are you inetrested in the shocks or just gathering info?

[gtrracer]

Please remeber these are twin progessive rate springs so you can't directly compare to linear spring rates.

Fronts are 700 lb with 250mm free length.

Rears are 400 lb with 350 mm free length.

I have raced and setup cars for nearly 30 years so I'm no mug in this area.

These work really well both road, rally and track both wet and dry and the only application that may need a spring change would be for dedicated track work.

Even saying that these hold there own on the track.

Have updated srping info

Can supply pictures if reqiured.

[-unknown-sss]

Can you supply the business name of who services these DMS coilovers in NSW? pretty keen.
