Lock spacers
 

Anyone installed any or can recommend some?

What are lock spacers? I feel like I should know what you're talking about, but I'm probably used to hearing a different term...

Spacers that give the steering extra lock for drifting.

Ah, I'm not sure about that. I know there are shops developing new knuckles, though. Parts Shop MAX, for instance. But I have no idea how long until they're available.

Steering rack spacers.

Megan Racing has inner tie rods with a small spacer built in. Won't give you that much extra angle though. The big difference will be modded knuckles, which as stated above, is in the works right now

I'm concerned the Kot above makes too many other compromises in geometry for regular/circuit driving. I think the angle gained from the kit is excessive.

I'd like to try lock spacers first.
