Hello,

Could you help me to select correct rod end. I'm not building a formula SAE car, it will be two seter, but main principles gona be the same.
Weight, i suppose, gona be about 350-400kg. I think what the main factor for selecting rod end is distance from lower und upper joint and the distance between inner joints.

Thanks for advice!

Rom, the reason you have had no response to your enquiry is that noone out here in Forumland has any idea what you are talking about!

sounds like your car might end up a bit heavy.

You'll probably be best with 5/16" heat treated rod ends

Try aurora RAM-5T (teflon liners)

sorry for my englisch http://fsae.com/groupee_common/emoticons/icon_smile.gif

For example if my car weight 500kg, and distance between upright p/u points is 230mm. Is there some principles how to select for cicuit racing rod end, and safety factor?

The weight is only prediction. I modeling car in solidworks. Now the weight is 235kg, but modeling is not finished yet. Engine i will take from hayabusa, CBR1100xx or ZX12. There are engine, frame, mannequin, wheels and steering wheel.
What about camber gain? If suspension travel in bump gona be about 50mm should I to pay attention at this?

its probbably a good idea. spherical joints only allow so much rotation. they do make high misalignment versions but their axial capacity is less and they weigh more.

what do you mean "axial capacity", could you explain? I don't knew such term.
