Spring rates for daily?

[nrubenstein]

Really? I've gone from H&R Race/Bilsteins to H&R/Konis to H&R Sport/Konis on full soft, and it still rides like total shit compared to my stock B5 A4 with factory sport suspension, particularly over poorly filled potholes, railroad crossings, road joints, etc. Tires may be partly to do with it since I have performance tires on the E30 and all seasons on the Audi. I can't imagine your 330i would have vastly stiffer suspension than my A4. Makes me wonder if something's wrong with my shocks.

He drives on Washington (state) roads, which, as I recall, are pretty smooth. Unlike, say, the DC area, where we have frost heaves and potholes.

I’ve been on 275 to 1050lbs. springs in the front of BMWs for reference.

275 is too soft for coilovers IMO. IIRC my original setup was something like 500/600. It wasn't so bad actually with good dampers, but I ended up putting the 500# springs in the rear and run 400# up front now. It's only slightly stiffer than my stock 330i with the koni's set to full soft.

If you have Bilstiens it's going to ride like crap no matter what though.

275 with an 8” spring is great with coilovers. You just have to preload the spring to get to the right ride height. It’s a LOT more compliant over bad roads. It works, even with a heavy lump of an S50B32 up front.

I'm going to stick with 400F/550R. Just got an email back from GC and Donovan said those are good rates for DD.

I think you want to be more like 275 in the front.

Is 400F / 550R too aggressive for DD duties? Maybe some of you guys have something near this setup and can recommend.
