Hey everybody - thank you very much for all of the advice & input. I went with the 500 series, Swift springs, 8k front/16k rear. I posted some pics at the end of the thread to show the stance. I didn't go too low - I'm old. LOL

The build quality is impressive and they look real nice out of the box. Awesome finish. Mind blowing quality. Major bang-for-buckage here & made in the USA!!

Thanks again everybody & to all of the threads about spring rates & brands to consider. Couldn't have done it without y'all.

Orig post:

I've been reading through many threads re: spring rates. Want to say thanks to everyone who has posted some great info & insight. Y'all are fantastic!

I've narrowed my choices down to two:

BC Racing, DS Series, standard variant (not extreme low), Swift Springs upgrade & default spring rate 7K/mm (~392 lb/in) front, 14K/mm (~784 lb/in) rear.

Fortune Auto, based on info I provided them with how I use the car & my goal for the suspension upgrade, recommends their 500 series, Swift Springs with 8K/mm (~448 lb/in) front & 16K/mm (~896 lb/in) rear spring rates. I can also get the 7/14 K/mm combo.

I do not know the actual lb/in rates - I just used an online converter to determine those. Both mfrs only show rates in K/mm.

Curious to know if any suspension geeks out there can comment on expected ride quality changes. There are a lot of you that seem to really know your stuff on this subject!!

OEM ride quality is not as bad as I thought - but it is definitely jittery/bouncy on lousy CT roads. Some are bad enough that I feel the car lose grip/hop a little at times.

Appreciate any help/insight on what I can expect with these set ups, which spring rate option you might go with. I am leaning towards the Fortune Auto set up, so it's the spring rate I am most interested in hearing your input about.
