Modified Nissan Skyline GT-R Suspension and Alignment Specifications

If you don't have a stock car, then here are a few suggestions for alignment from a few sources:

First - from Mr. GT-R, Hiroshi Tamura


  • Recommends up to 4.5 degrees negative front camber and 1.5 negative rear camber.
  • For short circuits use up to 5mm (13/64) toe out front and 0 toe rear for all circuits.
  • For street use he recommends 10kg front and 8 kg rear spring.
  • Track use he recommends to reverse them or 10 kg front and rear.
  • When using 15-18 kg front - use 2 kg softer rear
  • Set up car like a front wheel drive car
  • Attesa system relies on the factory ECU to sense engine load and when you change the engine load mapping , it affects the attesa system response
  • He uses LSD type front diff for some short circuits
  • He likes 245 tire on a 17 x 9 20mm offset wheels for R32 . Or 17 x 9.5 with 265 tire
  • Disconnect Hicas for circuit use
