Whats the total weight with driver? the 300/250 rear springs sound pretty stiff for a metric car. If its in the 3000-3200lb range I would go lighter rear springs, 250/200 range. 50 lbs of bite is also pretty low for a metric car. I would add another 50-75 lbs of bite and see what you think. More bite and cross % will free up the car on entry (off throttle). Eric

Now I don't run a metric, but I have heard a few things some are doing. So here it goes. One guy runs a inch taller LR spring sometimes 250-300 rate. Another thing I personally realized that seemed so simple. A few years ago our division changed over to Hoosier g60. We were running around 3.5 neg camber on the RF. We are now up to 4.5- 5.0 deg of negative camber. Noticed that the sidewalls at just rolling over. Changed that and the car drove totally different ( better)
