I only use it on the street. The ride feels kind of bumpy - but I've never ridden in another classic car or another maverick before so I don't have a point of reference New moog suspension on the front, but 45 year old shocks all around. Don't know how much shocks would affect that either - the front feels alil bumpy too.... All rubber bushings
I If you find the ride is to bumpy/hard, remove the bottom (#4) leaf; that will make a difference. I agree w/ Rasit -- dump those 45 yr old shocks! I have 4 KYB Blacks on my car, they are reasonable priced and they look factory. Also, they ride nice. I assume road conditions in NC has better roads than hr in Midwest and the fourth leaf on my car was to much kidney banger.
add-a-leaf ' spring setup ... as Crazy said, I put them on a worn out set of stock 3 leaf and they did nothing. I guess I was thinking they would rearch the springs... the way Chip used them are what they are for. ...stiffen up leaf springs when going to add weight to trunk...
