fitted the redtop to the Corsa b and all seems fine apart trom the bump steer which causes the car to 'wonder' down the road. This can depending on the road turn into torque steer adding to poor handling. I do understand the difference in bump and torque steer please dont confuse the two.
The car has generally very goop grip and torque steer is no worse than expected.
The suspension is uprated but not of a quality set up, just Gmax springs and shock absorbers lowered 40mm, although the front has gone further now due to the increase in weight.

Has anyone got any sound advice about eliminating the bump steer issue? I understand i will need to uprate the suspension, but before i go chucking cash in the wrong areas can someone give and sound advice from their own experiance.

Jake, that is a superub definition of bump steer. I have spoke to many peolple to day and concluded that i just need better springs and shockers. The advice is to get specific courtney 2.0 front springs and bilstein front shockers. This should restore the ideal ride height and good bound and rebound control with the damper.
