Hi,
For parts SMD sell all parts for all the cars they sell including TCO2C/X2C :

The fastrax turf rippers are a little disapointing as in grip levels but might be ok on wet grass. The schmacher's provide the best grip on astro and not far behing the ballistic's. When silverstone first got astro we all used turf rippers as that's what the club sold at the time but they were never going to be as good as the schuey's.
Hope that helps,
Steven
