billet alloy uprights and arms

[GianniGiudici]

Hi

do you know someone that sell and build billet uprights and alloy arms?
tvr originals are always rusty!

cheers

Would they be strong enough ? Unless you made them out of some expensive materials like titanium or something I thing the strength would be a major problem.

Gianni which car do you have i know someone who has CNC'ed them from billet for the T cars

Porsche are cast alloy.

what model do you want them for ?

[dvs_dave]

Loads of cars have alloy suspension arms. Would be interesting to develop a "bolt-on" suspension set-up that was able to address some of the geometry shortcomings associated with the standard set-ups.

Thesev have just been made for the latest Sagora conversion .They have been machined from billet but worked out quite expensive . I am looking into a modular version so rideheight and track can be adjusted while hopefully costing a bit less .

[BliarOut]

Do they significantly reduce unsprung weight?

Would it help to reduce costs if they can be produced for Griffs/Chims?

Having been involved with the development of ally replacements for steel suspension components, there is nothing wrong with using ally (right grade of course) providing the part is designed to provide the same strength etc. This means that it should not simply copy a steel component. So making a ally copy of the steel wishbones is crazy as the material has different strengths. Designing from a scratch a replacement wishbone with the same geometry is another matter but it is not easy as there is a lot of work needed to ensure that it is as strong as the original steel version.

Agreed, you can't just copy the steel components like for like for the reasons you've stated, but if you're going to the trouble of re-engineering the suspension components, you may as well try and sort some of the other known geometry issues whilst you're at it?

Alternativley you could use an existing ready made suspension set-up from another vehicle/race car and then develop adaptor plates to allow fitment onto the existing chassis suspension mounting points? Might be a cheaper and more effective way of doing it?

This is what I meant when talking about the strength. Alloy could be used but it would require a complete redesign of the component taking into account the strength characteristics of the material used and the loadings that will be placed upon it.

thanks guys
i have a cerbera
and i'm looking for the uprights and the arms, both lower and upper but in alloy.

teh one in the pictures are nice but were can i buy that parts?

cheeeers

[shpub]

The Cerbera uprights are already alloy so can't see what would be gained here...

[dvs_dave]

Fronts yes, rears no. Same with the T-cars.

[plasticman]

The alloy rear uprights are only about a kilo lighter from memory .There primary function was to lower the car while maintaining a horizontal lower wishbone . The camber adjustment on the top wishbone is by shim rather than sliding bolt.All the wishbones have been made in T45 CDS tube. A large part of the weight is the jeep bearing pack and hub and that is possibly a place to start investigating .

Hello

yes but i want a fully billet ally one

mine are totally rusti and horrible!

also
is it possible to fit the Sagaris lower and upper arms?
or they are different?

cheers

[GianniGiudici]

Also where i can buy them and what price?

[GianniGiudici]

nothing?!

[Slow M]

Gianni,

Mi Amico, you bought the wrong car, that's all. You need an M. Mine came with wonderful cast aluminium rear uprights that polish beautifully, and nickel plated wishbones. Gorgeous and purposeful.

Gianni, I tried to email you but your profile does not allow it , David
