WHY VFT (Vlamos) RUBBER SUSPENSION BUSHES?
Suspension bushes are some of the most highly stressed components fitted to a motor car. They undergo enormous strains and are subjected to the most arduous of conditions, generally with little or no maintenance or lubrication.
VFT bushes are specifically engineered precision components, which have been designed to replace the worn or aged OEM factory original bushes without compromising or altering the original suspension setup.
At VFT we utilize only the highest quality materials and components, resulting in products that meet or exceed OEM specifications.
Because of their superior design VFT bushes offer greater effective control of the suspension components, particularly when compared with the plastic or urethane type products.
With the technological advances in modern rubber materials, it is possible to reinstate the factory ride and NVH levels whilst maintaining the factory hardness, tension and torque characteristics, and even include factory design concepts such as the shock absorbing slots. The end result is a perfect ride the way the manufacturer intended the car to ride. Firm, supple, predictable suspension without the harshness, squeaking and increased noise which is often a common problem associated with the harder urethane and plastic type products.
By correctly engineering the rubber materials and the vulcanising process, VFT bushes can be custom made 10-30% stiffer than standard bushes, whilst maintaining the exact same noise absorbing properties of the standard OEM rubber items. This assures a continuation of the optimum performance and reliability associated with your Lexus automobile.

The OE rubber composition of the factory bushings in our Toyota/Lexus SC300/400 has deteriorated over time - hot/cold cycling road salt and other extreme road conditions will accelerate this condition. This bushing failure problem can occur in as little as 50,000 kilometers and almost always by 100-130,000 kilometers. Some symptoms of this deteriorated bushing problem are:
Replacing Your Bushes
Replacing the worn OE rubber bushings with VFT Bushes is a sensible and much cheaper alternative to the stock replacement control arms available from Toyota/Lexus!
VFT bushes are an economical upgrade that retain the stock control arm/sway bar assemblies and hardware, providing increased road feel and handling characteristics that only the Toyota/Lexus can provide.
An increase in braking stability is also achieved with VFT control arm bushings as the control arms will not shift or oscillate forward and backward under the extreme lateral loads experienced during heavy braking. If other suspension upgrades such as springs struts or sway bars are installed the benefits of each will be maximized when used in conjunction with the VFT bushes.
Ever spent the weekend replacing those old flogged out suspension bushes ?
Like the factory originals, the centre sleeve in most replacement suspension bushes is not designed to rotate within the bush. Rather the outer casting and centre sleeve are bonded together via a rubber membrane. It is the flexibility of this membrane that allows the suspension to move up and down. So if you jack up the car and tighten up the bolts with the suspension sagging at full droop, the bushes will twist to nearly the full limit of the flexibility when you drop the car off the jack and the suspension moves back up to static ride height.
A few miles down the road, when the suspension tries to move up over a bump, there's no give left in the bushes and they start tearing themselves in half.
The moral of the story : If you are fitting new bushes or if you are simply lowering your car, it is extremely important that you first loosen the cam bolts / sleeve bolts when altering the height of your car. This is particularly important for SC400’s and V8 Soarer’s as their bushes have shock absorbing slots and to a lesser degree in the SC300’s and 6 cylinder Soarer’s as their bushes are solid. It is paramount to wait until the car is sitting back on the ground before finally tightening the suspension mounting bolts.
This way the bushes are not pre-stressed or deformed at the static ride height and have plenty of give in them to allow the suspension to move through its full range of travel without tearing those new VFT bushes to pieces.
Celsior and LS400 VFT Bushings will be available in June or July of 2004..
