Possible/good idea or not?

Explain a bit more walt iam having a blonde moment ???????

What about adjustable/excentrical mounts at the top of the shock towers instead? Imho that would give you more adjustability and stability.Those are available for Golf MK2 and they fit on the 02/03 also don´t they?

Wally's point:

As the stock suspension geometry is lowered, the design of the lower arm becomes a problem. At a certain point (when the pivot angle >90 degrees) the wheel gains positive camber as the suspension compresses.

As per this-


on the left, stock ride height, compressing the suspension results in more negative camber (blue shadow). In the middle, the lower arm is pointing up as the suspension is lowered so further compression results in the bottom of the tyre being pulled in. On the right, the balljoint is spaced downwards from the spindle reducing the angle between the lower arm and the strut to less than 90 degrees. This fixes the problem.

The other option is the raise the inner mount of the lower arm. Changing the strut angle will reduce the key angle but not by much and it adds a lot of unwanted static camber.

If you could machine a spacer with the correct tapers and internal/external threads this would really improve the handling of lowered cars. As a bonus, it would also fix the similar issues with the anti-roll bar.

Thanks Bruce, that is EXACTLY what i meant! Not sure if possible with new arms from Lee, but if there would be a way to incorporate the extension, then that would make it an extra selling point and I would want a set now as I am contemplating extension possibilities at the moment.

The higher up mounting on the inside is theoretically a sound alternative, but the arm is already on the high hole of the mounting (as original) with '74-> suspension and higher is fysically not possible there..

Whats the weight difference with stock arms Lee? Seems like it would be hard to shed weight on the original design, but would be happy to be proven wrong of course! It would be nice if the extra weight of the extension(s) - which would be heavy - could be made up some by lighter arms!

Right o iam with you all now wally you cant believe the weight difference between the two moly is so light . so what we need is higher ball joint end ????

Yep! I have some 9cm clearence towards my 18"wheels from underside ball-joint to wheel rim. I think 2 inches higher will fit any other wheel, make it worth the trouble and be effective enough?

BTW, I really like light-weight in suspension components!

Already do these versions just about to make them adjustable next little project.

[70Turbobug]

I understand perfectly what the extension does and it´s more than likely the cheaper solution.But you are also multiplying the torque on that joint between the extension and the arm.Possibly of no concern,though? Maybe thomas07056 can share some experience on that from racing?

Hi

With the ball joint extension picture that Wally just posted they could be made to make the fitting of the 944 stubs easier instead of using an adaptor bush.

On another tangent. Real weight gains could be made with a 3 bolt set-up using molly lower control arms, those cast lower control arms weigh quiet a lot.

We never use adaptor bushes, just buy the german ball joints thats what those are in the pics, id never trust a bush.

Great 2 problems solved in one, much better than the adaptor bush

another way of doing it would be to use a spherical bearing rather than a ball joint in the outter end of the tca. that way you can then use a shaft to attach to the strut. this shaft can then be made adjustable in hieght so you can set it up to what ever ride hieght you want. this is commen practice on many rally/race cars. yes a spherical joint might be a bit much for a road car and wont last as long as a ball joint but it works and is very strong.
this is on a golf but uses the same idea

Regardless of what people think or prefer,I´m sure you´ve given your products a lot of thought and sounds like you wouldn´t sell anything without trying it out and giving your approval first.It´s good to see that another person is offering quality products to the acvw community! Keep it up!

[Wally]

Yeah, I would REALLY like to try this new tca on my car for the new TimeAttack2012 season. Which starts BTW already in march Lee, so get on with it!
