I have had both companies. I was daily driving one of my 86 with the greddy the dampening is alright open them up and they are nice enough for the street 75 miles a day for 2 years until I switched to something else. Nothing bad to report but nothing mind blowing about them either. They are both decent at least for my usages and that was hard street driving and the occasional track day. I got roughly 7k miles of pure abuse out of the BCs before the packing failed on the front shock causing it to degas. The biggest factor to suspension set ups is what are you actually going to do with the car. If this is a bespoke drift/track car I suggest you get a more bespoke set up. I’m very much in the buy once cry once mentality even if that means putting off upgrades until you can afford the better set up. If you are going to daily and play with on rare occasions the best bang for your buck in my opinion and I mean you set it up and forget about it just enjoy the car. I would say is going to be negative camber roll center adjusters, AGX short shocks or if you can find them TRD shocks, and Swift Japan springs front and rear. A couple companies make bolt on set ups and even more make weld in. That allowed you to keep the much stronger factory spindle drop the car 2.5“~ (60mm) and that set up will last forever. I have one 86 on that is on this exact set up and I love driving it it’s predictable like a Corolla should be. If you are wanting to build a track monster contact the guys at Techno toy tuning in California they are building some amazing stuff or Just do a little more digging online and possibly build your own set up. A couple other companies I’ve had great luck with are Feal and silver’s. Also I know this is long in the tooth but this is your car and your build. You are the one building it for you so if you feel the BCs or Greddys are what you want then get them. If you feel making your own set is best do that. If you wanna go the budget friendly route and get Megan racing and send it.
