Where is the best place for the rear springs? Behind, in front, or on top of the rear axle? What are the advantages/disadvantages of each position?

Thanks

Scott, we use the locations for the springs as tuning tools. The only spot I do not agree with is on top of the axle. Especially in a mod. You can not use the rotation of the housing to your benefit this way.

it all depends on what type of suspension you are using

What type of chassis do you have scott? there are many variables that play into answering this question. You can get some good advice here that may not be applicable. Give a few more details and maybe someone can give info that is better suited to what you have.

We run a Pro Chassis, with a torque arm and monoleafs supported by sliders. I personally think that the springs infrot will cause a greater lever effect, thus planting the rear tire harder. It was just a question because all of the cars I see now, run the sliders behind. Thanks for the replies

I just saw a new Castens chassis today, it had the left spring in front of the axle and the right on top of the axle. IT was a three link with a pull bar. These cars seem pretty quick to me.

I'm very near the end of a project where I cut the whole rear clip off my car and changed it from a 3-link torque arm to a 4-link w/ floated brakes (6-link??...bitchin', dude..). For my spring mounts, I've built perches on clamps that have the mounting holes on axle center and 3 1/2" off center. I can put it in front of or behind the axle by removing the clamp and turning it around. I plan to put on a lot of laps at at least two test days changing them around and running it right away so I can note the differences on the same surface. The best way to find anything is through trial and error seat-of-the-pants feel..better to make your errors when it don't cost you a race.

Hope it helps..
Matt
