I got a 73 240Z last fall and spent the last year gathering the 72 intake and a header, along with a ton of odds and ends parts. Got the thing running sweet now, but I fear I made a costly mistake in simply replacing the tires with a set of new, in the same size.(BFG's 245/60R14) They look slick on the car, I'm an old guy and like the fat sidewall and raised white letter look. The problem comes in when I get the back end into a slide while curving to the left. the front left tire hits the tip of the lower fender extension. This is easily fixed using a fiberglass spoiler. The second is more significant. The original owner, who has died since I got the car, modified the struts with longer (and softer) springs so I rub tires on dips and bumps. All the spring setups I have come across can be lowered, but I need to go up like a 1/2 inch in the rear, and 3/4 inch in the front. That would put me exactly where I sit now. I'm looking for a source for a complete, adjustable coil & strut set that can be adjusted for height & damping. Also, I want to get stiffer spring rates as well. Anybody have an idea of a place to start my search?
