This little rod I bought has rear coils. It rides like a lumber wagon. Every little bump is rough. The spring cal. says they are 214lb springs. If my 225lb buddy try's to push it down it will hardly move.Would dropping down to 150 help this thing?
Any pictures of the set up? the angle of the coil over can make a difference too.( decreases the spring rate the steeper the angle...to a point where they become non effective as a suspension member.) also be sure the shock is still good, it could have gone bad and be binding? but 214 # does sound a bit high for that car im hopefull 200# in my Tudor will do the trick, so far it acts right , but shes not on the road yet.
I've got a pair of 225# TCI All Americans on my 29 roadster and I think it rides pretty good. Firm but not harsh. I think 150s would be way to soft. You may try 180s or 200s. Remember these Model As are on a 103 inch wheel base so they will be a little choppy.
no coil overs. The rear is out of an A body Chevy. The springs are pretty far back, they are behind the rear end. They used a nice Pete and Jakes front set up and did a hack job on the rear.
Need to make sure the suspension is free without the springs, whether they are mounted in a slider or whatever. Maybe some bushings need to be freed up.
The old trick on that used to be Corvair front coils. I would have to side with John Evans and say 150lbs would be pretty close. Depending on the what they are, might have a bit of a hard time finding them these days. Elpolako and I were playing with this a couple of weeks ago, and we hit upon the idea of Chrysler K car rear springs. There were several rates to choose from, and they were a constant wound spring that was in the three and a half to four inch range. Of course, I can't see your set up, but before you say it's "hacked", you need to know that this was a very common rear spring setup before the days of the 1-800-rod-shop world we've known for the last couple of decades. All things considered and set up right, it works really well.
