I like the spec tire in general because way back in the 90's i started to get in to touring car racing and Proline came out with a premounted tire set that costed 60.00 a set and at our track it was a huge advantage and they didnt last long(s3 compound i think). As much as I loved it, im not rich and long with batteries and motor of the week it took the fun out of it for me.
Now 9 years later im giving it a try again, the Cs 27 seems to work at a lot of places and it holds up well and they are not 60.00 one run tire sets.
You car has enough tuning options that you should also need to have the "HOT" tire of the week to compete. My 2cents
