B4 front hub carriers
 
Hi there

Can anyone tell me the changes that will be made to the handling of my B4 when using 20 degree, 25 degree (kit) and 30 degree hub carriers ?

According to the B4 manual, the higher the castor amount the more initial steering you gain and less exit steering...and therefore if you run less castor you get less initial and more exit.

However, before I started racing 2WD I was always under the impression that more castor gave less initial and more exit, whereas less castor gave more initial and less exit.

Maybe its different for 2WD and 4WD? I have no idea :)

From the B4 tuning manual-

• Use 30° of caster (optional #9593 caster blocks) if you need
increased steering entering corners and less steering exiting corners. It
will also be more stable when accelerating through fast bumpy track
conditions.
• Use 25° of caster (#9580 caster blocks) if you need less
amount of steering entering corners than the 30° blocks, but more
steering in the middle and exiting corners.
• Use 20° of caster (optional #9592 caster blocks) if you need
even less steering entering corners and more steering exiting corners.


hope this helps.

Yup as the B4 manual says, 30 degree is good on the B4! Wouldn't bother changing from anything but 30 on the B4

I've tried all three block indoors over the past few weeks - the bigger caster angle seems to make the steering smoother, without really affecting total steering (a small decrease perhaps, but nothing dramatic).

30 degree blocks (indoors at least) do seem noticeably better, they give a much smoother steering balance than the 25 or 20, and suit the car well.
