I am suffering with a tram lining effect on my car at the moment which doesn't inspire confidence when trying to use it's power. I seriously doubt it's the coilovers though but more to do with castor/camber.

My ride isn't harsh except for the most severe of bumps and I am running gravel spec dampers with 250 front springs and 170 rears. I have a set of 275 springs to try on the front but I am not sure if I am going to yet.
