Car pulls on the exit of a turn

[djhedges]

On the exit for turn 12 at Portland International Raceway as I unwind the steering wheel for the front straight the car pulls to the right. It's a right hand turn in 3rd gear and I've been full throttle for a few seconds. It's just before the steering wheel is fully straight. It feels like something is unloading or unbinding. It doesn't matter how smoothly I try to unwind the steering wheel it always abruptly pulls and then everything is fine.

 

My friends and I are building a 91 Civic Si for chump car. The suspension has new

• Poly bushings
  
• New rubber trailing arm bushings
  
• New struts
  
• New lower ball joints
  
• New tie rod ends
  
• New steering rack
  
• OEM springs
  
• Integra trailing arms
  
• Integra rear sway bar (1mm thicker than OEM)
  
• Aftermarket slotted upper control arm with new ball joints
  
• 91 EX Honda Spindles

 

Front is toed 1/8" out

Rear is zero toe

 

This problem is a bit hard to search for so I'm hoping someone who races a Honda has come across this.
