How to get rid of understeer in a 1970 340

Recommendations:

  1. Stiffer front T-bars ~1.0" or greater.
  2. Stiffer front anti-roll bar. A 1 1/8" bar is available.
  3. Rear anti-roll bar. Even those that mount on the axle are better than nothing.
  4. Same size wheel and tire F/R. Larger rear tires promote understeer.
  5. Fresh F/R suspension bushings. Polygraphite preferred but even new rubber bushings better than old ragged worn out stuff.
All the bushings were changed last year ,used polygraphite all around . Will look into the Hellwing . I beat the new crap boxes yes , but when I push it I get understeer , not when braking into turns but when accelerating into long sweepers or accelerating out of the turn . Feels like the front wheels are lifting and the car is not responding to the steering .
KYB had those on my ramcharger in the 70's , those ride hard real hard. What about Koni , they still around , worked well back in the day , will also look into bilstein . Have a feeling the KYB will rattle my teeth , a least that's what I remember in the ramcharger , up here with the potholes and rough roads they might break the car .
