My s2erst seems to have extremely heavy steering are there any common things that can cause this, the cars been lowered on a spax sportkit and polybushed at the front, could it be steering rack??,track control arms, etc...........the steering is worst oviously when trying to park/slow moving but its still heavy when driving, its a pity because its spoiling the car and im toying with the idea of selling up for a nice power assisted cossie but id love to sort it as i love the car ..........................please help , thanx
