Darren with regard to all the S series rear ends apart from using different suspension arms all the location points are the same , i lined up s13 s14 s15 subframes and the main difference is diff mounting change and the different designed camber arm to clear the shock/spring. The reason most people would go with the s13 might be that there more available since larger build numbers of the cars and with the two different length diff housings in ca to sr cars making many ratios available.Personally i run a adaptor spacer so i can change between the two with the same tailshaft. If you stick all the point on the subframe and hub into any suspension program you will find that binding in direction rotation isn't a problem if all arms are adjusted to there standard length. With standard points the ratio between them within standard amounts of travel will work fine , but if you change any of the lengths the ratio is out and them movement/distances of travel will cause more a pulling action then binding.

Anyway under the weight of the vehicle the weak mounts would just bend/flex which causes the geometry change that might be worst than any hope that solid has in performing better and controlling over rubber. Then main issue really comes with the rear design being great at high ride heights and progressing worst in camber change and toe closer to full bump. I double checked by graphing the changes at different ride heights with string lines after testing a few times and it confirmed the problem. I relocated a point then changed to different bushing's and pillows in location's where there would be a problem if i needed to adjust geometry. This might not be a problem in your country just the track's here are so rough that worn t50's will alway's pop out of gear :wink: here most people are aiming for between 140-210hz wheel frequency, what is the planned rate for this car ? and its usage.

I find it interesting that you want to control the roll moment without exerting any roll stiffness with a bar . No matter how low the center of gravity i wonder what effects in a 53/47 balanced car it has on the roll axis though transient movements where forces of change in direction add to the loading. How is a soft rate going to control that ? do you have active suspension planned ?
