SXE10 Altezza rear camber



Uneven rear camber values on SXE10 TOYOTA Altezza were corrected yesterday. Because the right side wheel base was prolonged the other day, rear wheel alignment and constructive geometry were changed leading into various discrepancies everywhere in rear suspension construction. So, made up I my mind to correct it into zero thrust condition yesterday. As we know, camber adjusting can not be done independently, instead moving rear wheel vertical inclination causes toe discrepancy, consequently, they should be done together with at the same time when scaling and setting both toe and camber inclination. The procedure proceeds by reducing so to speak tolerance trying and cutting several times with patience. 75 minutes negative camber value was applied on rear wheels under the condition of 2 mm toe-in(tire outer surfaces) with zero thrust. The importance of establishing zero thrust condition in the car is emphasized especially on FR models like Altezza. We can easily imagine that the thrust line is the key to push the object straight forward in playing Billiards game.
As mentioned before, vertical inclination is measured with DIY special Pendulum device 1,719,75 mm radius reading 2 minutes per 1 mm at it's measuring point, horizontal checking is done by the level device imbedded with LASER pointer.
