Kyosho RB6 - Roger Mills - Steering rack

- Kyosho RB6 - Roger Mills - Steering rack - Calming the car -

I've had a few people mention that the RB6 is a little "pointy" for them. The solution is an easy one, if you reverse the steering rack so the moulded in arrow faces back you will move the track rod ball studs back 1.25mm which will help calm the feel of the car.

If you want a bit calmer feel still then try using the LA246 low profile ball stud which moves the ball back a further 1mm.

This combination really helped tip-toe around a super slipper Kiderminster yesterday morning and I will probably leave the rack reversed and use longer ball studs / spacers to go back to the original positions when appropriate as the ball studs can be got to without taking the rack apart.

Just another great tuning aid for the already very adjustable car.

Forgot to mention that you unscrew the ball studs and then screw them back in facing forwards after reversing the rack ... I know it sounds obvious but I'm sure somebody somewhere will forget

The reason I did it was when I first got the RB6 I found it was very darty & pointy to the level that I was having to take 3 bites at most high speed turns. I'd turn, the car would bite hard so I'd reduce lock to stop it hooking then it would start to push lightly so I'd have to get back on the lock. Certainly not the easiest or fastest way around the track.

The car was very good over the bumps and had good / balanced grip but just needed smoothing out a little to build confidence, reversing the rack did that.

The difference is 1.25mm, I often combine that with a low height ball stud so -2.25mm over the normal rack position with no spacers.
This gives a significant ackerman reduction / change thus smoothing the car.

I like a car with a lot of mid-exit steering but that isn't too pointy / agressive on the way in.
