My Viking coil over spring has the numbers 10TP350 on them. Is this the spring rate and is this the current springs being sold. I thought I read that CBR had changed the rate?
You may have the compression and/or rebound knob(s) dialed too high. Reduce the setting to zero and try moving the suspension up and down. turn the knobs back if the suspension now moves. Then drive it to see if the compression or rebound need tweaking to your liking. I have mine at +2 on rebound and +4 on compression. Easy to experiment the different settings. I can reach in and adjust the setting without jacking up the car.I can barely bounce my front end now, 450's would be worse. Is 350 the current shock rating for a small block 67?
