For the sake of packaging I would like to run my protech coilovers at an angle close to 45" very similar to what the Haynes roadster front
suspension runs at.
Is this a terrible idea? Google search suggests the maximun angle should be about 30 degrees off horizontal
Cheers

Something you need to remember is that the effect of the springs you are using will be affected by the angle ie if they are upright you multiply the
spring rate by the sine ( 90) =1 if they are at 45 degrees you multiply by the sine(45) = 0.7 but also as the suspension is compressed the angle
worsens and the spring in effect reduce in rate.
When you mention 30 degrees that's 30 degrees from upright ie actually at 60 degrees sine(60) = 0.87.

Hi. There is no issue in running the dampers at that angle in terms of it physically working. 30 Deg is about as far as you really want to go as the
fall of rate increases dramatically after that, but if no other choice then as mentioned the damper and spring are not really doing there job and you
really need to be looking at getting dampers modified and revalved to work with the application.
This is also where so many kitcar manufacturers loose the plot by recommending spring poundage's that are way way out for the application and
dampers are barely even working. Depending on exact suspension design and ratio of wheel to damper movements you can end up with a car driving down
the road with 8mm of wheel moment over the bumps and ripples in road and the damper is barley moving 1mm IE the spring and damper are not doing much
of anything
