with rubbing post alignment when had it set to 8F 12R. I raised the car up about 1/4-1/2" and got rid of most of the rubbing unless I hit a harder bump. The crappy thing I'm still frustrated about however is that all 4 have different max values which seems like a crappy quality control issue. (FL 15, FR 16, RL 19, RR 14) I e-mailed Charles with no response. Makes me wonder how many people experience this since another person responded with the same issue on my other post. As much as I love powertrix products, it makes me wonder if I shouldn't have gone BC Racing since my BMW coils are ALL 32 clicks to max... not 1-3 off like Powertrix. :/
