TLDR: whose running stock style springs instead of coilovers, which are you using and do you have any issues with bottoming them out?
Curious to see what you guys are running or having luck with.
I'm looking for a dual purpose setup for both street and auto-x (probably more emphasis on the street)
I've acquired a full e30m3 suspension setup so I have the ability to adjust roll center to correct for lowering and will do the offset rear subframe bushings.
I've been perusing the e30 spring rate thread and I think my stock 325e springs are:
106 front / 245 rear (baseline/stock height)
the e30m3 springs that I have should be:
140 front / 250 rear (.75/1" lower than baseline height)
Where I'm getting hung up is most lowering spring reviews seem to talk about bottoming issues and being too soft etc etc. What's confusing to me about that is relative to the m3 springs I'm only seeing .5-.75" of additional lowering but spring rates taking a similar increase as 325 to M3:
H&R sport 180 front / 340 rear 1.5" lower than baseline
The IE stage 3 springs seem like they'd really suit the bill at 2" lower than stock and spring rates of 315 front 575 rear but they're out of stock and no sign of when they'll be back.
I'm trying to avoid going to coilover as don't want to modify the NLA front struts but I recently discovered the JOM front coilover sleeve which seems designed to work with unmodified fronts. Something like that might be an option and would allow me to chose better spring rates?
