I'm currently in the process of rebuilding my rear suspension on my ex-CSP CRX and looking downgrade the rear spring rates from the current 450lb rear springs on my OPM coil overs. The car will see primarily daily use with the occasion auto-x and open track day. Currently I'm running 27mm torsion bars in the front which from what I understand are the equivalent of 375lb spring. I'm also running OPM camber plates, illumnas, no front sway bar, and a pretty gigantic rear bar. The question is what rear spring rates will offer me the best trade off between comfort and road feel. I'm debating between 250, 275, and 300lb rear rates hoping for a better ride but I don't want ruin the fun or ability to rotate easily in doing so. If anyone has an opinion or some feedback I'd greatly appreciate it. Thanks again, J-Man

Most of kits that sell go from 250 to 300 lbs. 300lbs are stiff but are streetable, and good for track.

Go with 350s in the back, and change your front torsion bars to 24 mm.
Still a little stiff, but good for a street/track combo.

Well thank God for that, 'cause if I wasn't, this would probably have never worked.
