Full set of 8 xT45 Rose Jointed Wishbones.

Our EP Tuning Race Wishbones are expertly crafted from the best materials for the application namely Aircraft specification certificated T45 steel tube.

The spherical bearing tube ends are CNC manufactured from the best EN14 steel, even the welding wire is specific to the process to keep the welds as strong as possible and alleviate any possible cracking.

A huge amount of time has been spent on the design and development of these as they have to be precisely accurate to within a few thousandths of an inch which is quite difficult to do when any welding is involved.

We have alleviated this problem with the design and manufacture of the best CNC manufactured jigs that take into account any shrinkage caused through the welding process. The order of how the welds are put down in specific rotation also makes a difference when you are welding to these very accurate tolerances.

Expertly TIG (Tungsten Inert Gas) welded to the highest standard and argon gas purged atmosphere creating a smoother stronger weld.

We use the highest quality NMB spherical bearings of which 16 are 30mm OD and another 8 are 35mm OD.

Fully assembled ready to install on your race car, they are supplied with 316 grade stainless steel conical spacers and new wishbone pivot bolts.

Black Xylan coated for the ultimate corrosion protection, although only 5-10 microns thick its properties reach far beyond that of zinc coating.

Military vehicles and aircraft use the same process as they have to resist the highest levels of corrosive salt spray tests currently applicable.

The original Lotus wishbones are made from seam welded steel tube which is cheap to manufacture but because they are seam welded the wall thickness has to be high to keep the necessary strength.

Ours are designed to be lightweight yet at least as strong and much stiffer than the originals.

We have done this by using larger diameter tubes in some areas and because T45 is such a good material we have managed to reduce the weight by over 1/3rd.

Original set of 8 MK2 VVTI wishbones weigh 18 KG our Full set of 8 weigh less than 12 KG.

Our wishbones have been thoroughly tested on many race cars; the latest has just won the GT championship outright in Australia.

Depending on your set up there are various other adaptors and bolts required to complete the install but please contact us for the finer details.
