my name is Thomas. I am racing a Gr.A Rally Mini in the Austrian Rallye Championship. Here a video from the last season:
Sadly we had an accident at the end of the last season and now we are rebuilding the Mini. I want to use the situation to improve the handling of the car.
There are two things I dont like one thing is the very bad torque steer and the other thing is that the car gets very nervous on bumpy roads. I was using red spot rubber cones at the front and standard at the rear, GAZ shocks, minispares race anti roll bar at the rear and 6J13 Wheels.
To get rid of the torque steer I want to use spherical jointed tie bars and lower arms. Furthermore I got the advice to set castor to 0, has anyone tried this or other ideas to reduce torque steer?
For the other problem I want to change to coilovers. I think that the rubber cones dont give the suspension enough room to work when the road is very bad. In my thoughts that shold be better with a coil spring. I have an old but little used Spax coilover set that I want to try. I have read that the rear springs of this set are too hard. Is there someone with expierience in using coilovers for rallying? Which spring rate is working?
Would be very happy if someone could help me with my questions.
best regards Thomas
