Can you tell me what your 4 link's specs are so I can plug them in to Dan and Greg's calculator?
I like how you have like zero rear steer and that's what I'm trying to accomplish. At least I don't want to have oversteer when turning. However, I've got to deal with the fact that at the frame end my links have to be higher (frame is 25" off the ground) than I like.
I don't have a lot of options for link locations (without hanging in the way) so I end up with like -7° roll axis angle at 7" of compression and 10° at 12" of droop. I picked those numbers because that's what travel I get with leaf springs.
I can only go 50" forward of the axle centerline and I can only go 4" rearward of the axle centerline. The bottom of the frame is 25" from the ground (wish it was 24" or less but that'd leave me no up travel in the front unless I went coilover and full hydro). Maximum width in the front is 35" and maximum width on the axle is 51". I have 12" of available height up front. Height on the axle I'm only limited by the moment arm of the bridge on the tube.
