Cure for the tramling is the 4s. I went 305/325. The handling is night and day. I took my Cup2's off at 500 miles. This is the best mod I've done so far.
Perhaps the factory peddle setting is off. With the car off(duh) put it in first and use your foot to lift up on the peddle from underneath. Then press down on the clutch. You should hear/feel a "pop" as it adjusts. This should lower the bite point.
