KW Clubsport Coilovers 2 Way Suspension

We have just taken delivery of a KW Clubsport 2 Way Coilover suspension kit for our Astra H Sprint track car, which will be fitted over the coming weeks and set up prior to its first outing in 2015.

Here’s a preview:

What makes KW so good? Apart from their build quality, assembly process, attention to detail and technical support?

Their durability and resistance to rust, meaning KW coilovers continue to work, unlike cheaper competitors where spring perches corrode onto the struts making adjustment impossible.

All KW coilovers are made using high quality and perfectly matching components and materials. So both their renowned racing applications for international motorsports benefit, but also your KW coilovers for the road.

All KW coilovers, Variant 1, Variant 2, Variant 3, Street Comfort and the adaptive KW DDC coilovers from the KW iSuspension range are made from stainless steel. Whether the strut or the trapezoid thread or the vehicle-specific connections – KW only use stainless steel. KW stainless steel “inox-line” coilovers in conjunction with corrosion-resistant springs and elastomers stand for a long-term driving pleasure.

  • Highly corrosion-resistant
  • Unsurpassed quality
  • No signs of wear at the adjustment mechanism – also during long use
  • Trapezoid thread in stainless steel eases height-adjustment
  • Perfect look – permanently
  • High load tolerance

How resistant to rust are the KW coilovers “inox line”?
KW wanted to know precisely and therefore worked together with the Fachhochschule (University of Applied Sciences) Esslingen. The chemists and engineers of the FH tested the KW coilover struts made of stainless steel. So in total nine coilover struts from six different manufacturers went through a quality check.

Brake and Chassis Upgrades – Astra H 1.9 CDTi

Enhancements being carried out to the brakes and suspension on an Astra H 1.9CDTi (150 PS) 3 door sport hatch.

To improve the chassis our Courtenay Sport Clubman Plus fast road suspension upgrade was fitted, which is a full kit that includes original equipment (OE) genuine Astra VXR dampers and a set of DAP Road springs, which not only improves road holding but also lowers the car by around 25-30mm.

The front and rear brakes were upgraded with EBC Turbo Grooved front and rear discs with EBC Red Ceramic (fast road) pads all round, and the system was bled with DOT 5.1 fluid.

Speedline Turini Alloy Wheels

Type 2120 – Turini. 8″x18″, 65.1mm, 5x110PCD ET38mm (possibly ET35mm) for Astra H VXR fitment.

We would like to have these Speedline Turini flow-formed 18″ wheels manufactured for Vauxhall/Opel fitment. If there is enough interest we will get a small batch of wheels made in 3 colours: Silver, Anthracite and Gold. The flowforming process makes these wheels extremely strong and light. They are fully heat treated up to motorsport specification and ideal for trackday use.

This would be a limited production run of wheels, meaning we do not need huge numbers of people to get this moving for delivery early 2015, and limited numbers would mean a certain level of exclusivity.

Target Price £936.00 per set of 4, depending upon the level of interest. (List Price £1008 inc VAT)

Please contact us as soon as possible to confirm interest giving your preferred colour. There is a contact form at the end of this post. If we achieve the desired numbers an order will be placed with Speedline upon receipt of payments from all participants.

Specification: 8″x18, 65.1mm, 5x110PCD ET38mm (possibly ET35mm) for Astra H VXR/OPC fitment. Will clear big brake kits such as AP 4 Pot and K Sport 8 Pot/D2 6 Pot.
These will not require a ‘fitting kit’ (spigot rings) or wobbly wheel bolts.

Colour Suggestions:
Gold suits White and Arden Blue cars.
Anthracite suits Silver, Red and White.
Silver suits most colours.

An iconic Speedline design, the Turini wheel is known for it’s classic good looks, durability and light weight.

The wheel comes with the ‘seal of approval’ from some of the worlds most important car manufacturers, as an original equipment option or line fitment. The 18″ version employ the world renowned Speedline patented Flowforming production technology, ensuring the ultimate marriage of low weight with high strength.

NOTE: These wheels are listed as available online on other suppliers’ websites, however having spoken directly to Speedline they have confirmed there is no stock of these wheels in a correct Vauxhall fitment, except by placing a minimum quantity special order.

FLOWFORMING – What is it and how does it differ?:

Speedline’s flowforming process is a unique solution to a common problem – how to make a wheel both light and strong.

Speedline’s flowforming method is unique within the wheel production industry, and patented.

This means that only Speedline can provide this precise technology.

The casting used to produce the wheel is much narrower than usual, but with the same amount of alloy that would be present in a conventional casting.

The casting is then placed in a specially designed machine within an additional mould. The hot casting is then spun at high rpm within the mould, and formed into the shape of the final wheel.

The resulting grain structure within the alloy of the wheel is linear, flowing in a single direction (see image below).

Cast versus Flow Forming

Cast versus Flow Forming

This grain structure pattern (shown above), combined with the exceptional quality of casting required for the process, gives the rim area of the wheel huge mechanical strength, and elongation. As a result of these mechanical characteristics, Speedline are able to reduce the thickness of the rim area resulting in reduced weight, without compromising strength and resistance to impact (see images below).

As can be seen from these images above, the flowformed wheel rim profile is much thinner that the usual cast wheel, resulting in lower weight and reduced inertia, making the wheel respond faster to acceleration and braking forces.

Astravan 1.9 CDTi Stage 3+ Tuning Package

We had this Astravan 1.9CDTi here recently for a few days undergoing some fairly extensive upgrades to cover the engine, brakes  and chassis.

Performance:
A Stage 3+ conversion. The van was fitted with our hybrid turbo charger, full 2.5″ stainless steel exhaust system (turbo back), full height CSRacing Intercooler and 80mm Air Flow Meter with revised inlet air path. At the same time an oil and filter change was also carried out.

After the hardware had been fitted, it was round onto the rolling road for ecu remapping and a full set up, which achieved 223bhp and 377 lb ft torque.

Braking:
At the same time a K Sport big brake kit was fitted, under the 17″ wheels, to greatly improve the stopping ability over the original factory 308mm brake set up. Red 8 Pot calipers, 330mm x 32mm 8 grooved and ventilated front discs with EBC Yellow Ceramic Pads. The brake system was bled through with DOT 5.1 brake fluid.

To ensure adequate clearance between the wheel spokes and the calipers a TÜV approved 3mm spacer has been fitted with longer 28mm black wheel bolts.

Handling:
The van has also had our Courtenay Sport Clubman Plus fast road suspension upgrade which is a full kit that includes original equipment (OE) genuine Astra VXR dampers and a set of DAP Road springs, which drops the chassis significantly, as can be seen on the before and after pictures below. Ideal for fast road and light track day use.

Gold Plug Magnetic Sump Plugs

Gold Plug Magnetic Sump Plug

Gold Plug Magnetic Sump Plug

Gold Plug manufactures Magnetic Sump Drain Plugs of the highest quality. Constructed from a 303 Stainless Steel body that houses the strongest, highest temperature, N45SH Neodymium magnet available.

The magnet is secured in place with a proprietary 2 step process and will never come out. Advancements in technology and materials means Gold Plug is continually evolving and at the forefront of technology.

The strong Neodymium magnet collects any swarf or wear particles missed by the oil filter. These particles are abrasive and potentially damaging to the engine. The magnet will hold any collected metal firmly, unaffected by temperature variation until the oil is changed.

Magnetic sump plugs are a proven product and even used by some manufacturers as standard, examples are available on the market today however few match the quality of Gold Plug and those that do are very expensive.

  • M14 x 1.5 for most Vauxhall Sumps.
  • High Quality Stainless Steel.
  • High Temperature Neodymium Magnet.
  • Collects particles which are not filtered out by the oil filter.
  • Simple to Fit.
  • Made in the USA.
  • Includes Sump Plug Washer
