take a look on petit for Ben Smith setup at Herts last year as an example. You do need the dirt inserts to achieve the “later” letter settings and depending on what you run, different length driveshafts may be required to retain correct engagement in the drive cup. I think it might be the dirt car UJs in this case.
Just circling back to this now I have played with the rear hubs some.
Initially I was running H (wide) and that was nice, I changed at a practice session to B Narrow and that was horrible, really locked in the rear and then was unpredictable when it let go.
Last time out I tried F (wide and low) as that was what a mate was running. Much nicer, rear end while freer was much more predictable, only comment would be it had a little too much on power steering and not quite enough turn in.
I think I will either go back to H or try F wide and high (as per Ben's Herts setup you suggested). I think for our track that may lock the rear in a little too much, I know at the National with the number of cars and layout change the sand came up a lot at the National so I can see F wide and High being good for that.
I think with the flat Mezzo tyre it's all about keeping the car flat if you need the rear grip or using the lower RC heights to allow the car to roll off the tyre tread a bit to free the rear end. Slowly getting my head around...I think.
Thanks for the help.
