Hey, I need some coilovers for my car since the suspension on it now is not good enough. I keep on scratching my back tyres. I got a good deal on some Konis for the front and Sachs for the back, with "some" coils. They are about one year old. Should this be good enough and will it just be a straight install? My E34 is a '89 if that matters. Thanks in advance.
