Which spring?

[mwh57]

Hey everyone. I'm putting together the front end for my roadster and ran into 2 options I'm not sure of. I am going with a buggy spring front and coil overs in the rear. My questions are, 1- spring placement Behind or Over, what are the pros & cons. 2- spring eyes Standard or Reverse. I am looking to do some long runs and want as much comfort as is possible with buggy springs. More important is trouble free miles. Any feed back will be helpful. Thanks.

First, welcome to CHR! I hope you find what you're looking for here and enjoy a long ride.

From your profile info in the upper right it appears you're building a '27 Roadster Pickup? Your asking questions related to ride and comfort, but the answers are going to affect the stance of your truck more than the ride. Stance is just about the most critical design issue you'll face related to the "wow factor" of the vehicle. I'll offer that my buggy spring front (Pete & Jake's dropped axle, 5 leaf spring w/slider pockets, mounted above the axle) is very stiff but it tracks beautifully and drives great with no bump steer. My rear coil overs are much the same, and I think I will be going to a softer, slightly longer spring on them to try to improve the lumber wagon shock to the spine on bumps at some point in the future. I may also look at removing a middle leaf from the buggy spring at some point, when I've got nothing better to do....

Some basics to consider are that front springs/schocks are at an area of the chassis that is pretty constant in load where as the rear is subject to a much more pronounced variance of load from occupents weight plus fuel and /or trunk/bed loadings-the rear of a coupe/roadster(2 passenger vehicle) with 2 passengers can vary as the passengers could be say 200# each and fuel load easily vary 100 more lbs plus trunk weight (chairs,cooler,xxx) the front loading won't be effected as much----------this will most likely result in shock settings that are considerably different rates compression/rebound front to rear????????

Spring on top, reversed eyes.
The spring behind creates issues with the tie rod you want to avoid

There's more involved too... What style front cross member do you have ?
