Cat SX/SX2 setup change frequency

[/tobys]

I'm researching which 4wd car to get and considering an SX2. As this isn't out yet, I am assuming that the setups will be similar to the SX (despite big bores on the SX2).

There seems to be a wide range of settings and options that can be used, certainly it appears as though there are more compared to B44 and BMax4.

So, my question to SX owners (past and present) is: Once you have got a base setup, how much do you need to deviate/tweak between different tracks?

I think the SX2 looks really good (I drove a Cat 2000 EC for a single meeting about 12 years ago and it was one of the best 4wd I had ever driven) but I am concerned about "chasing the setup" at every track I visit - which I don't want to have to do. Naturally, I understand small tweaks are required on every car when visiting different tracks and I can get my head around changing springs/oils/piston, but factoring in wishbone spacing, anti-squat, castor, one-way, chassis material etc would concern me. Looking at the setups (posted on the schumacher and the petitrc sites), to an untrained eye there seems to be little similarity/commonality between the them and I would guess it can be easy to lose you way with it?

Anyone care to comment on their experiences? I guess I'm looking for some reassurance that a 90% "base setup" can be achieved which then requires only minor tweaks to achieve the final 10%.

Thanks guys
