San...I would suggest going with one of the D3 setup sheets but turn down the boost and go to a 7.5FDR to start....or there about. Not too many places race boosted 17.5 on carpet anymore here in the US. After Vegas Im sure SP will have some more setups as its a class there. Until then you might be on your own with alittle trial and error you should be in the ballpark I would think.
