QUOTE(Woody @ Nov 15 2013, 05:53 PM)  QUOTE(nolift914 @ Nov 15 2013, 07:16 PM) QUOTE(sean_v8_914 @ Nov 15 2013, 12:19 PM) lots of great recommendations from very experienced racers here... springs store energy. stiff springs store more so the release (off-loading) is quicker. more skill is required to manage that faster release and to be ahead of the car as you go higher in spring rate. shocks dampen the spring energy. shock valving should be matched to spring rate. big changes in spring rate require changes in damper rate. im sure many will disagree with the correlation between spring rate and skill level. I am sure you are correct, that why I post here. I am trying to learn as much a possible. The 914 has re valved bilstein's which I now believe are matched to the springs. I think what I was experiencing was a high spring rate with a very low grip level from the med compound r45's which resulted in quick under-steer with little warning. With the increased grip level of the 35's the suspension is working as designed. In addition to the driver catching up to the car with the added seat time. Looking foward to next season! Driver catching up to the car. Story of my life. +1 (IMG:style_emoticons/default/smile.gif) |

Use charts as reference to get yourself in the neighborhood. Every 914 handles
differently under the same settings and every driver has their own style. Test, adjust, test, adjust, test and accept changes using your own ass. There are so many variables. But, you know that... What works great at Sebring, sucks at Lime Rock. If you think tires are important, try asking someone what pressures they're running. |
