Castor correction

Do you know if rhinordys arms are castor corrected.

yes for 2 1/2 inches

I spoke to Ray this morning he told me his arms are 3 inch castor corrected he also says he fits genuine suzuki bushes as they flex more. Rays arms are £260 including delivery which seems good value to me.
I should receive my arms next week, I'll let you know how it feels once I've fitted them.

This is crazy have you never heard of M.E.D ( minimum edge distance)
Do not do this it will all end badly
Infact i wouldnt recomend any of the ways posted as they all drop the arm at the front reducing ground clearance , real corected arms doot sit any lower than stock

Hello Reaper

Very good observation for MED

I calculated before drilling the tensile shear on the metallic walls under the new hole.

When the screw this fitting to the specified tightening torque, the friction between head of bolt and washer (nut side) and inner tube of bush with metallic walls, exempts of calculations. The high friction distributes the tensions. In the picture the indentation is observed taken place by washer in the metallic wall.

The extreme situation is when the screw this improperly adjusted. In this case, the force takes place a shear tensile under the hole.

I calculate this shear tension for the screw this improperly adjusted in the critical vehicle conditions (coefficients of friction tire/floor =1, the whole weight of the vehicle transferred to the front axle), in this case the shear tension in the wall under the hole is below the maximum tensile shear recommended in the low carbon steel, also below the stress of fatigue of material.

Thanks and sorry for my poor technical english.

Nice 1 Gustavo a man who obviously knows about Engineering material stress and going around a problem instead of just busting y wallet open and lineing someone else pocket for load of old rubbish up grades that are no more fit for road use then what you have done man after my own heart

Richie, I dont have a pic of my caster correction arms (Front only) but they are best described as similar to RR,s below

www.rhinorays.co.uk/ART/radius_arms38.jpg

But instead of the triangular cut outs they are round holes. They are obviously by a manufacturer and not home built but I dont have a clue who, can anybody identify them from this simplified description? Im now thinking of getting my hands on a set of RR' rears so it will be interesting to see what yours are like when they come.

And what of the top of the hole that has next to no wall thickness , im still very sceptical of the wall on the bottom and wouldnt trust that on road nevermind offroad
And as said before you are still dropping the front of the arm way down into harms way , a good hit on that and it will rip that hole like butter

I did notice to radius arm is very close to the steering arm in one of the photos
