When the camber is incorrect, it causes the weight of the car to transfer to the general inside edges of the rear tyres. This effectively changes the diameter of those tyres. With the front and rear tyres of differing diameters, the viscous coupling is being operated all the time, even in a straight line. This has the effect of generating more heat for the transfer box to deal with. Under normal circumstances the viscous coupling would only run when the wheels spin or on anything but a straight line. provided the tyres are in spec.
The general aim is to keep the txb as cool as possible.
Richard, I emailed you regarding a rear camber kit today and will contact you again shortly
Has anyone had any experience with tyres scrubbing at the front with -40mm springs? I had -30mm on my SRI with no scrubbing at the front but the Turbo is a lot lower. There doesnt seem to be negative camber at the front of the car (especially when comparing with the rear).
The front kit is probably out of my price range and I'm assuming that the rear is more important?
