You know what's really impressive? All of that original text was entered into the computer using voice dictation software - RSI FTW! I just had to make minor corrections and formatting after I was done.

Glad the information is useful, and as an update, I'm still loving this suspension setup. Over the years I've found that tire selection comes into play when tuning the handling. When I moved to Bridgestone RE11's last fall they introduced some understeer which I dialed out by increasing the stiffness on the rear shocks by a quarter turn.

Don't be afraid to experiment. Autocross and skidpad/figure-8 exercises are a great way to explore the settings in a safe environment. You may find settings you like for autocross aren't quite right for a track day. Minor changes can have big effects. Have fun with it!

I really do think 500# in the rear is not enough. Check post #20 by the OP!

In my case, I was also bottoming on 560# before I upped it to 672# in the rear then swapped the 560# into the front and sold the 504# I had on the front. Never any problems afterwards.

Even the OEM springs, I believe, when fully compressed do exceed 500#. There is a chart I ran into on e46F that had rates per inch compression of various progressive springs applicable to e46's.

That said, I've read of spring setups exactly like yours but usually paired with either stiffer shocks/adjustments + near empty trunks.

After, reading post 18 and 20 might go with 450/700. But not sure! I'm worried about my full audio system in the trunk and meth tank. Gotta call TC Kline and ask their opinion.
