Tod,
A 70 on 1600 has a standard front suspension height of around 380mm and
320mm in the rear. Bump steer begins to be a problem at around 320mm (with
the stock x-member) and excessive -ve camber in the rear starts to happen
below 290mm. As you have 240K struts the thinner 240K insulators may have
also been used as these are 15mm or so thinner than the 1600 as usually a
240K strut with a popular heavy duty spring (Lovells, Pedders etc) gives
around 320mm on a 1600.
Your car must be fairly nose down and possibly be a bit twitchy in the rear
when cornering as well as suffering from bump steer. The 1600 should not
have any more than 25mm nose down attitude to handle at the best of it
capability. The 5mm difference in the driver's side measurements is quite
typical of a suspension that done a few kays and nothing really worth
worrying about.
regards
Terry

Hi all, I am trying to find the best ride height for a 1600 that is suited
for street driving that doesnt cause the bane of all lowered 1600's bump
steer. The best way to compare is to measure the distance
from centre hub to guard lip so if youve got a tape measure handy could some
of you post your measurements for comparisons, could u also list the struts
etc you are runin. I beleive mine is way too low at the front and this
combined with the offset lower control arm bolts has made a mess of the
geometry ie lots of bump steer.
The current setup is 240k struts, lowered springs(unknown brand) and sports
inserts(unknown brand), offset lwr control arm bolts.
The heights (guard to hub centre) are:
Front Left: 310mm Rear Left: 320mm
Front Right: 305mm Rear Right: 315mm
Does anyone know the stock heights as im pretty sure the rear of mine isnt
far off stock. I am thinking i may try putting the stock control arm bolts
back in and obtaining some 180b offset strut tops but im not sure if this
will give a suitable amount of camber, anyone?. I recentley replaced the
steering box with a 120y unit as mine was very sloppy due to the excessive
bump steer id guess, i also replaced all the tie rods, but i havent replaced
the idler arm/bushings could this be another factor adding to the bump
steer? I think i will need to obtain some strut spacers to correct the
geometry otherwise. Thanx in advance.......Tod
