    Custom radiator arrived which looks the business but it needs some slight alterations




    We stripped the struts down and welded them up, tested them through the travel on the car and had to make some further changes



    We then after looking at the strut design on other cars decided to try a different route to improve things
    Looked at the setups on newer Hondas and then Renaultsport cars, Megane 225 being the easiest to come by

    Removed spring collars to turn into a coilover setup



    Did not document progress from here all that well but see below different iterations

    What are the benefits of that over a Nova knuckle?

    What have you been trying to improve in regards to suspension geometry??

    Seems like a huge amount of work for possible gains over a proven available adjustable suspension kit.

    We can get between +1 and -3 degrees camber and 5 degrees of caster with out kits. Admittedly bump steer is still an issue but are working on that.

    Interesting read thanks. So in short:

    "By positioning the steering axis closer to the wheel center, a major cause of torque steering, the amount of center offset, was drastically reduced."

    So this is all about reducing torque steer rather than giving extra geometry adjustment. You find the torque steer particularly bad on your test days?
