My wife bought me a hotchkis sport suspension set for christmas for my 68.. it is supposed to drop the car about 1.5" from the factory ride. I am into the 70's style big wheels in back smaller up front and am currently running 275-60-15 on 10 " dishes in the back . The tires stick out about an inch at the top and when i hit a large bump the fender will scrape on the top of the tire . I was thinking of putting a set of air shocks on when I install the springs . what are the pros and cons of running like this ? will the car still hook-up ?or will the rearend just bounce around ?will I get any plus' from the springs ?
