7/9 ( personal BB) or for ABS 0 wheel : 6/8, for ABS 1 - feel free to use your preferred brake balance. I recommend to run 2 click higher at the rear.
Recommended setting for DS3 user :
Steering sensitivity at +1 or +2, all aids off, except ABS 1 ( if not comfortable with ABS 0 ) with 8/10 brake balance as starting point.
Notes :
I always wanted a nicely built CRZ, for this 450PP version, I used different approach than usual, Street Tune
For a start, I go for turbo in order to achieve necessary power and decent torque delivery that won't hurt the tire too much.
Then suspension comes from J's Racing Showa Street Sport Coilover with low spring rate aimed for street comfort but also still fun at at the track. The coilover allows 30mm max drop at front and rear, spring set at 2.8/3.9, some might think, wow, that's just too soft, but don't worry, as the car is lightened at 1040kg, and excellent damping, the ride is supple but firm Front damper is set to avoid excessive dive under braking, while the rear is set to achieve better traction on exit and mid corner.
ARB has been set at moderate stiffness at 3/3, giving good steering response and still nicely planted on mid corner.
For LSD, I have used 1 way low preload, with low locking rate to help with reducing push on exit when using lower grip tire. An alternative for those who can take advantage of better traction and good throttle control is 33 acceleration sensitivity.
Transmission has been fixed with corrected gear ratios, and final gear from 2014 CRZ model year which offers higher final ( lower top speed + better acceleration ). Additionally, the 3rd gear has been replaced with MFactory 3rd gear set at 1.357. The stock 3rd gear is too wide spread from 2nd, as it was set for city/highway driving. With the Mfactory gear set, the spacing is perfect now and offers brisk acceleration
The weight distribution has also been fixed at 59/41 as in real life spec. The J's Racing CRZ was tuned and tested at Tsukuba, Willow Springs Street, Brands Hatch GP and Bathurst
When tested at Tsukuba on comfort soft, it's capable of 1:05s lap.
ENJOY
