my mk3.5 fiesta zetec turbo running about 280/300bhp was fine with adjustable lower arms and gaz gold coilovers ,the problem is that most people with a modified car buy suspension etc , fit it and then dont have the car set up correctly. it also had power steering which helped with the torque steer , i remember when i picked it up from grove garage and drove it to ian howells house and let him have ago in it , he just couldnt believe how little torque steer the car had , in the end i had to take the keys off him!
