Best way to cut the castor blocks?

[Cassp0nk]

Hi guys, whats the best tool/approach for cutting the castor blocks?

[Cassp0nk]

ok did it

Dremel cutting disk and 2mm drill bit for extending the pilot hole through. Bit of a faff given no one wants 3mm but I guess its not cost effective for schumacher to fix the molds?

It enables you to lower the front outer pivot ball height by approx 3mm - by skimming the shoulder and grinding it flat with the remainder of the block.

On high grip tracks like many of the ones over here, this helps reduce some of the front end bite (a reversal of lowering the inner pivot if you like).

You can always shim the pivot ball back up to standard height but you may need longer threaded balls to do this since 3mm of the material they otherwise screw into has been removed.

Hope this helps

Which inner pivot is being lowered? The upper camber link?

[Gnarly Old Dog]

Yes - I mean the inner pivot ball of the upper camber links.
Lowering it tends to make that end of the car more aggressive and increases bite. Raising it does the opposite and takes away some of the bite.

The reverse happens at the outer pivot.

Come and find us at EPR and we'll work it through.

All the team drivers here do it, so I felt I must follow sheep like

My setup is probably going to be a mess though as I can't go the whole hog on all their options as Schumacher are too tight to include enough spare shims to play with setup out the box. GRRRRRR
