We got involved once the car had already been built and asked to help them sort out the aero. A press release on that here: http://www.amb-aero.com/mca_s13_amb_aero/JordanMugen wrote: ↑Wed Oct 17, 2018 1:04 pmVery interesting stuff!gixxer_drew wrote: ↑Mon Oct 01, 2018 1:12 amAlso on your earlier post about the smaller diffuser on MCA. The diffuser was "stalled" when we started work on the car. The spoiler addition in 2016 made a lot more rear downforce and reduced drag but did so even with producing some lift on top of the rear diffuser overhang.
Originally we designed the spoiler and shorter rear diffuser together for 2016 but only the spoiler was completed in time for 2016 event.
Is there a good reason the MCA team uses a S13 Nissan Silvia and not a S13 180SX? I would guessed the shallower C-pillar angle of the 180 would be a better base for time attack platform...?
So those decisions were made before we had any involvement. I prefer smaller cars these days. From about 3 years ago we shifted focus for time attack cars to efficient production as I felt it was the low hanging fruit now and downforce could be whatever the tires tolerate or drag allows for.
