Hi all
I have had an LX SS hatch, since 1990 that has, what I think, is a UC front sub-frame with aluminium mount steering rack.
I have HZ brake stubs with WB discs and aluminium calipers.
My question is, I have about 2.5 degrees of I think negative Caster (the one that makes the steering heavier).
This was done years ago when I used to race the car and now I'm driving it on the street more often I wanted to reduce the caster back to RTS specs to make the steering 'lighter', for want of a better word.
The car also used to run -5 degrees camber, great for the track but wanted less for the street.
Prior to being adjusted for racing the wheel alignment was standard RTS with -1.5 degrees negative camber.
I had the car wheel aligned by a reputable place and we got -1 degree camber but couldn't get less that 2.5 degrees of caster.
The wheel alignment guy suggested I get 3mm ground off the mating surface of the upper pivot arm to allow for more adjustment.
I know the front sub-frame has most likely sagged but over 15 years the camber/caster measurement hasn't changed except for what's been done recently.
Surely there is a better way to lower the caster than grinding the upper pivot arms?
thanks in advance
Hans
