Small update, I've moved to a new thread on designing my own front SLA suspension. Regarding the OTS kit from AE, its nice, the tubular front cross member is perhaps the best of its kind on the market. Part of me wishes they used slot-nuts instead of their current configuration but its not a huge deal.
Interesting, sorry to hear. I find their rear suspension pretty well designed, the rocker ratio is 1:1 which is not great but nothing you can't fix by making your own. Though for $4000, I feel it should've been disclosed at the very least. Their new packaging system for hardware is great, though their shipping packaging is quite bad. Their customer support offered to replace some parts that were damaged in shipping, need to follow up to check what the ETA on those RMA'd part is.
Regards to you giving them feedback, not surprising. I've also tried starting a technical discussion with them that they didn't seem super interested in, understandable they're running a business and are more concerned with keeping the doors open than answering questions from a guy that already paid them lol. These guys are developing kits for a bunch of Datsun/NIssan chassis, and now the E36 chassis so I doubt they have a lot of time for guys like us.
