Hi there,
I went down to fulcrum to check my alignment and tell them about my problem and they found out that the castor is almost align.
According to them the castor for cars like silvia,soarer and skylines, need to have the Front Left Tires a bit more to the front. Only way to allow that is to fit a adjustable Castor in it.
Just a reminder when changing the upper arm bushing which is usually worn for skylines, go for the adjustable type which cost almost the same.(It is a common problem and can be fix by replacing with after market plastic bushing and firm up the steering and handling.) Approx. 250-300 bucks
Anyway. The advisor in fulcrum advise for a wheel alignment to be redone. Since Bob Jane Screw it up. Cost my another $88 at Fulcrum.
After the realignment. The Steering Wheel is straight and the pulling left problem is greatly reduce to be very little.
