RND Motorsport proudly present the Spherical rear beam bearing kits suited to the MK5 Astra H, including VXR

Spherical bearing kits are designed to replace rubber bushes with free moving, perfect position retaining spherical bearings. Far superior to poly bushes, these remove all bind and retain geometry perfectly, allowing for a large increase in feedback from the tyres through the chassis, allowing you to feel them communicating with you. The rear bushes are known to deflect under steering conditions creating a passive rear steer effect. Without this your car will be more predictable and you will carry more speed round the corners.

As they are merely a pivot point most vibration is not passed through them when driving normally, it is only when lateral G's are being built that they transmit energy to the chassis, so they are not as harsh to live with as you may be thinking.

They remove all movement other than pivot out of the rear system.

They feature;

Dust Protection Seals.

Maintenance Free, PTFE lined, High Precision Speherical Bearings.

High precision CNC manufactured Components.

These are the outcome of years of extensive testing from us of longevity on british roads and multiple cars. Proved to dramatically improve the feeling under all driving conditions - if you like the best quality and performance in your suspension then these are for you. Looking for those vital few seconds on lap times, these again are for you.

Fitted to a many high powered track only Astra with only positive feedback. A memorable comment described how it was now easy to hold a four wheel slide around the long sweeping right hander at the end of the pit straight of Oulton Park!

This kit up for sale will include two complete bush units to replace the rubber inserts on your rear beam. Approximate fitting time would be two hours- the old bushes will press/chisel out very easily

Please contact us for over seas postage - we will send them but will have to quote upon request

Adjustable Cam pulley for the Inlet and Exhaust Camshaft of the Vauxhall Z20 engine.

This pulley will allow you to time your camshafts to deliver maximum power where you want it, ideal for use with aftermarket or alternative OEM camshafts in your turbo Z20.

It includes the sensor ring on the backside, as shown in the picture above, so that the ECU is kept happy no matter where you position your exhaust cam.

For maximum performance when fine tuning on the dyno we recommend using a pair as this will then allow you to fine tune both the advance and the overlap to extract maximum performance from your engine.

This is just for the one Cam Pulley pictured in the first picture above. See our other adverts for a combo of both  at a discounted price.

For fitting instructions please take a look at our technical info page for this item - Cam pulley info 

You probably also want to consider a fresh cambelt and waterpump whilst you are in there replacing these, which are also available from us.

Designed to replace the standard oil cooler pipes and their all too often leaky flexi joints.

Made with Hydroscand EGEFLEX1 EN 853 1SN hydraulic hose meaning they are more durable and flexible than the standard Vauxhall part.

The final and nicely suprising benefit of using our upgrade hoses is they are actually cheaper than the standard Vauxhall part.

Need we say any more...

Astra K03/K04 Turbo flange- this flange will not fit the corsa VXR K03 

Suitable for welding to 3" TUBE 

Internally profiled for best possible flow out of the turbine area. 

Made from  304 S/S  

Fits KO3/KO4/KO6 Astra Turbo and retains the use of the standard exhaust clamp. 

Convenient for when making new downpipe.

Gear shifter spacer units ,   ideal for getting the gearstick that bit closer to the steering wheel for more comfortable rapid use. comes complete with all mounting hardware . 

Initially developed in a taller version for stripped out car interior usage , these are smaller in height but still give a better position than standard.   These are as tall as you can go without having to remove the centre console.  If all that is alread removed you may want to look at our taller kit, this is the prefered height for full track usage.

Some very mild trim modifications are needed to just get this to squeeze back in retaining the gear gator , its also a lttle bit of a fiddle to fit too. Aproximate fitting time of 2 hours total 

Gear shifter spacer units ,   ideal for getting the gearstick that bit closer to the steering wheel for more comfortable rapid use. comes complete with all mounting hardware . 

Developed for track usage on a stripped out car interior , feel free to fit them if you also run a stripped out fast road astra. 

This kit will rais the gear shift unit around 100MM ,  this is often the most you can go without having to customise the dashboard to allow the cables through to the engine.  

Astra VXR Inline fuel filter kit.

In more recent years through testing many Astra Vxr's we have noticed that there is an issue that is becoming more of a problem on some than it is others. The issue comes about due to the fact that the Astra VXR leaves the factory with a fuel filter that is deemed fit for purpose for the life of the car – this means its a non replaceable type fuel filter, the car at standard power should have no issues running.

This is not always the case, especially more so when tuning the car to much higher levels of power or living in an area where there is a greater risk of contaminated fuel. In such a case there becomes a point where the car can no longer fuel safely. The long term effects of this can be catastrophic for the engine long term and can also lead to stress on other items of your car. Through the car being unable to adequately supply fuel in the correct quantity would suggest that the filter is blocked, this will mean that your fuel pump is overworking itself by quite a lot. The fuel system pressure is regulated at the far side of the fuel rail in order to keep the pressure maintained across all 4 injectors, this is typically 3-3.3 Bar of positive pressure without any boost in the reference port. With a blocked fuel filter its possible for the fuel system pressure to jack up further pre filter and this will cause unnecessary strain and most certainly prematurely wear out the fuel pump.

The solution

There are two solutions, one is to buy a whole new fuel pump cradle from Vauxhall themselves, this will include a new fuel pump as well as the in built filter. Not the cheapest option by far.

The second solution is to modify the existing setup in such a manner that can allow the fuel filter to be changed at more regular and appropriate service interval. This second solution also gives us the chance to replace a standard fuel filter with something more performance oriented that has a higher overall total flow capacity. The design we have ended off favouring allows the customer to connect in this fuel filter without having to cut any of the OE fuel lines under the bonnet. By installing a new in line filter in a different location. The old filter can be bypassed internally in the fuel tank and eliminated from the system. On the high power setups we will actually remove this filter from the in tank surge pot to increase the capacity, only advisable to those who feel technically confident in doing so.

Advisable to fit a new fuel pump at the time of doing the operation, one less hose to cut off. Installing a new ASNU fuel pump with new filter will ensure you better fit the criteria for fuel pump warranty, fuel pumps fitted on old filters are always void of any warranty.

The RND Astra VXR In line replacement fuel filter kit includes :-

A Bosch high flow motorsport quality fuel filter

Bracket and fixings to attach the filter to the bulkhead
Clamps and fixings to hold the filter to the bracket

Fuel fitting for the filter to take the OE fuel line from the fuel rail feed side

Fuel fitting to replace the fitting in the fuel rail

Fuel fitting for new filter far side

 ***Teflon lined PVC coated stainless braided hose to join the fuel filter to the fuel rail ***

^^^ *NEW* - Now includes main fuel line from Racing lines - Aramid motorsport fuel line ^^^

In tank fuel hose to route fuel supply from pump direct to tank lid 

We have developed this kit to be as straight forward as we can although some technical knowledge is needed, its advisable to pressure test your fuel system to above its expected working pressure upon completion of installation.

We have run nearly 600 HP through one of these filter kits without issue, we believe that this would be the top end of this filters capability and regular changes would be required at that power. Contact us for spare filters, we have plenty in stock.
