Hi, just to report on my first day with the RCC shocks and the 21T pulley:
I first try out the RCC shock without the 21T pulley just to se the difference without any changes on the car, it really was a difference in the handling of the car it felt much more smooth I could really notices the difference with the old shocks.
I then when and install the 21T pulley but change the set up of the car:
Down stop front from 0 to -1
Rear from 7 to 8
Camber front -3
Tires Front 40 61mm
Rear 40 64mm
Toe in rear -3
Toe out Front from 1 to .5
Shocks RCC Front Red, 3 holes, 40W, Tower position move from 1st hole to 2nd hole
Rear Red, 3 holes, 35W, Tower position 1st hole
All the rest left the same:
Front Diff medium hard
Rear Diff soft
Front Anti roll bar 45°
Rear Anti roll bar 2mm, 0mm inner
Front Roll Center 1mm under
Rear Roll Center UPPER Low inner – LOWER LOW
I used the new 4mm Chassis.
The result was excellent the car was well balance for overall performance, no traction roll, and very good steering and good punch coming out of the corners.
