Message	Hi, :I wonder if this setup would change the travel of the upper arm? Not sure, you'd need to find someone with more info than I to answer that one :) That lower arm design is very similar to the Nagisa Auto upper control arm design. (Pic borrowed from Nengun website). Bearing inner and on the outer end they have twin heim joints (which UK and us "colonies" call rosejoints). The Japanese really do make some high end stuff, this is by far far the nicest FUCA design I have seen for Z32. The catch? About $920USD for a pair. Not cheap but again I have to wonder if powertrix style arms sell for $300 is it worth spending $900 on a pair of arms that will be the last you'll ever buy? :Hard to say. I don't know if SPL discovered the twisting :problem on their own or through Unique Auto Sports. :Why didn't UAS try to sell theirs in the US? I just recently :stumbled upon them a few months ago while digging around :on aus300zx.com. UAS probably could have sold a heap of :them here if they would have promoted them. UAS does :some very impressive custom suspension setups from what :I've seen on aus300zx.com Ha I'm just stirring -only so many ways to design a pivoting Camber arm right ? ;) Looks like the Japs have been on to the pivoting thing for some time -we in the West just like to think that we have rediscovered the wheel haha. UAS have sold some of their parts through conceptz and powertrix, but yeah haven't really gone global. Not sure why but I think alot of it is to do with production costs etc. That and pricing -it's very hard to compete with your vendors on price, however with boutique items I agree there would be a market for them. :Question...Are they bushed? No they use Japanese NSK bearings inner and outer. So the rosejoint is "captured" within the body and the king pin passes through the body, the bearings and the rod end. The outer edge of the arm is allowed to rotate horizontally but there isn't any vertical free play outside of the normal travel at the inner end of the arm. Looking at the SPL design; for the pivoting motion to occur I believe the rosejoint needs to be located at the outer end of the arm or else risk fouling on the body brackets under rotation. That said the SPL design is very slim so I may be wrong? I would tend to agree with observations that leaving the rosejoint unrestricted could be a bad thing.... The arm needs to pivot on a horizontal axis but in this case what is preventing movement up and down? Also without any body support that heim joint is going to need to be seriously strong. The UAS versino one arms bent M30 centre sections... This was rectified in V.2 but yeah that rod end on the SPL arm is going to be under serious load...
