In your opinion, what is the best way to help a 4/Z car turn in the middle of the corner without carrying the LF front wheel a foot in the air? LR spring in front or behind? Best bar angles? Please feel free to discuss
Thanks

I'm thinking about converting my car to a 4 bar LR and swingarm RR. I see people writing about putting the coil spring behind on the LR for dry slick. Where do you put it for tacky? On top or in front? Is the spring attached to the birdcage? If so, is the shock also connected to the birdcage? And if so, where can I buy a birdcage like that?

This question is forever going on. There are so many varibles that there is no pat answer. My old heavy ex monoleaf, now 4 bar car, has both springs in front, shocks in rear, on floaters. The engine is a little flat tappet 350; and it really steers great and flies on dry slick or dusty tracks. When its wet, the thing steers okay, but lacks the ponies to be fast. With this set-up and a full 32 gal. tank of fuel I get 51% rear.
Now if the chassis was lighter, had aluminum heads, and pinto spindles; perhaps the rear % would be such that I'd need to move the LR spring behind the axle. so...go figure

Gene, What are your springs and shocks connected to? Birdcage, axle housing, or something else?

Springs are on coil elimantors mounted to the floaters. As are the shocks. 200# lr, 95 shock,150#-200# rr 9 split valve,depending on what the track is like. dryer=softer. I try to maintain equal ride height no matter the spring rate.

Gene, What are floaters? Are they the same as birdcages?
