thanks Glamis. Not sure I understand the difference between high/low compression vs. just compression. Also curious if anyone has some helpful links or simple examples of each of these.The 2.0 has preload and compression. The 2.5 has preload, high and low compression, and rebound. I have my rear 2.5 set to 10 rebound, 0 high and 0 low compression, and they are still too stiff!
