Bmax 4 ||| 15 degree caster blocks
 

What's the feeling on these 15 degree caster blocks? Are the a must have?
Do they only work on a certain kind of surface of track? What benefits do you get over the standard 8 degree blocks?
Any feedback will be appreciated.
Thanks.

I have them, they are nicely made. essential? no not really, but I've seen the plastic ones get pretty beat up through use and abuse (not on my car). mostly ball studs getting ripped out or bent.

Now 15 deg over stock 8? I'm still sure I preferred my car before on 8, but I've made so many changes since then it's difficult to judge. Once RHR practice evenings start running again I'll be able to back to back them and know for sure. In theory it should soften the effect of the steering(input), increase stability and reduce some off power turn in.
Lee Martin and Shin run them, with 2mm shaved and spaced back on the arms, allowing for a new ballstud position on tge steering arm. This is in high grip.

I know a lot of the top drivers use them, sounds like, as you say not essential.
May still get a pair, fancy trying them, especially
as I run on high grip tracks.
