[QUOTE="Braahp, post: 757447, member: 21441"] Look at this chart. Shows the various force along the stroke of the forks. You'll see little difference with the stock springs and oem spacer vs. the .38 springs and 10mm of preload. Your stock springs were actually stiffer initially until forks were compressed more. Use the stock metal spacer. I couldn't get it to line up and space correctly posted here but you'll figure it out. spring rate (kg/mm) 0.35 0.38 preload 20mm 10mm - - Force@ stroke (lb) stroke (mm) 38.6 33.5 30 54.0 50.3 50 65.6 62.8 65 77.2 75.4 80 88.7 88.0 95 100.3 100.5 110 111.9 113.1 125 123.5 125.7 140 135.0 138.2 155 146.6 150.8 170 158.2 163.4 185 169.8 175.9 200 181.3 188.5 215 192.9 201.1 230 204.5 213.6 245 216.0 226.2 260 227.6 238.8 275 239.2 251.3 290 250.8 263.9 305 [/QUOTE]
