Alright so I need lots of opinions on this.
So, I found out why I was struggling so much to raise the rears. I guess with D2s they think you just want an automatic minimum 1.75"-2" inch drop in the rear. I'm trying to achieve between a 1.25"-1.5" drop like I have in the fronts. The spring length is 160MM in the rear. Almost all other coilover designs for my car have 170-180MM length springs. That gives me a 0.4-0.8 differ which would immediately solve my issue. Spring rate is 4.7k they make a 6k rear spring would that raise my car up 1/4" in the rear because slightly stiffer? There isn't a set Spring ID as it an S Spring so it is difference from top to bottom. I was on the phone with D2 technical I sent them pictures and they gave me most of that technical info and say "yeah that's as high as it will go in the rear", "out of all the Mazda3's that have called in 13 years you are the first that wants to raise it". LOL.
Technical said he could email the headquarters wherever they are in Asia and ask them about a longer perch and a stiffer 6k spring. He said that could probably solve the issue but there would be a cost (obviously). So he will email me back Monday or Tuesday with the info.
My question is should I even stick with these coilovers? I know a lot of systems where their rear drop is almost stock height or maybe an inch drop at the most. My fronts are 100% fine and I love it. The coilovers overall don't feel bad. They ride decent and have treated me well. There is the possibility of me spending $200-$400 for new perches and springs and it not fixing my issue. Or I can spend $1k for a new system which would be BC that I know has a good reputation for a cheap coilover in the Mazda3 Community for track/auto-x, have normal ID 2.5" springs, know for a fact it will fix my height issue, cheap to fix supposedly, and have people that know the coilovers better than me? Oh and Black Friday/Cyber Monday coming up so I could possibly buy new ones for even cheaper.
Oh and I want them a certain height for handling characteristics needed for my car on softer springs in the rear. Thoughts?
