You'll be glad you added the Ackermann.....the car will roll so much better and continue into and out of the turn without scrubbing off much speed.....
Post 362 we go thru bump steer on the rear of the cobra.....might help......
KMP 259 Phase 2
Will take you thru a complete steering change......we went with a Appleton rack & pinion
Good change.....I look forward to the improvement for you.....
