Rear springs for Ohlins?

So I have Apex ARC8s with a+45 and +62 offset with 235/40/18 and 275/35/18 Dunlop Star Specs that I am having a hard time fitting with my ohlins with the drop I want. As of now I have the kit springs and am about stock ride hight. I think I could go lower in front with some 5mm spacer. In the rear iwas thinking of getting swift springs to replace the kit ones and want to be lowered about an ince so the tires tuck a little if that is possible. I daily drive and auto X it some. I also want to start doing track days. I was thinking a 8" 672 rear spring would be good. Is that length good or should I get something else. I may want to raise it up to stock hight in the winter. I have the stock subframe bushings in the back so I don't know if I want to heavy of a spring rate. Maybe even Dow around 600 would be good. What do you guys think I should do or what have you done? Thanks

Yup I got the ohlins and camber plates from Harold at HP Autoworks. Great guy with tons of knowledge I just hoped to get some more info and experiences on here before calling. Anyone have anything to share with the group?

To be able to lower the rear of your vehicle more with the Ohlins, you will need a 65mm ID 9" spring at the rate of your choice. 672 in/lb would be the max. I would go without M3 rear subframe bushings.

OEM rear Ohlins spring is 10" in length.

Just ordered some 560 lb rear swift sprinds with trust sheets as well as the m3 front wishbone and control arm kit, and H&R 5 mm spacers. I figured if I am going to pay for a corner balance and alignment again I may as well do the m3 front bits at the same time and save a little labor cost as I bet it was just a matter of time before I wanted to do them. Now I need to save up for a LSD and the rear subframe bushings. I also have an e92 front sway bar and bushings I got from HPAutoworks a while ago that I have not installed yet. Man does HPA have any frequent buyers program or minor sponsorships or anything? I don't even want to add up the totals anymore. I will have a M//ini M//ean M//acine after the LSD and M3 rear subframe bushings.
