To assist with integrating the Mazda RX7 S4 FC front suspension into my Mazda 323, I've decided to see if I can create a solid works model for the suspension and then one for the Mazda chassis to see what fabrication work is need to integrate it. Looking online into engineering tutorials I found a site called Grab CAD community and a tutorial on there around spring design in solid works which looks fairly strait forward. https://grabcad.com/tutorials/tutorial-how-to-model-a-suspension-spring-in-solidworks-and-show-design-intent The main issue I have is the Lower Control Arms (LCA's) are a rather complex shape and will require me to up-skill in SolidWorks to be able to reproduce them. I'm in the process of sandblasting the part and taking some better images from which to model it. *UPDATE -- 1FEB17 nearly finished sketching the LCA and spindles

Mazda_323 The above link is for a suspension model I measured from the stock Mazda 323 suspension and setup in  the model creating tool at Racing ASP to assist in mapping the stock Roll Center and predicting the new roll center with the RX7 FC Suspension.

Having come across a Mazda FC shell cheap that still had a majority of the suspension components less the struts, I've decided to embark on swapping the whole front sub-frame over. This means creating new guards as the old ones won't cater for the increase in the track width and either adapting the sub-frame to suit the 323 chassis or vise-versa, which ever is the easiest. To accommodate the track width of the  FC will require several modifications: the center of the strut tops to be moved outward by 38.5mm The Frame rails need to be moved outward by 57.5mm Here's the comparison: Mazda 323 FA4US Vs FC Dimensions Vehicle 323 Mazda - FC Wheelbase 2,311 mm (91.0 in) 2,431 mm (95.7 in) K ingpin Inclination 8.3 deg 13.45 Length 3,820 mm (150.4 in) 1986-88: 4,290 mm (168.9 in) Width 1,595 mm (62.8 in) 1,689 mm (66.5 in) Curb weight 812 kg (1,790 lb) 1,223–1,413 kg (2,696–3,115 lb) Wheel size 175/70R13 205/55R16 ...
