well it looks like the mike's are thinking of bring x275 to the osca
(onterio street car association) up here in the north
i don't have all the detale , i think it just to see if there will be any interest
from the cite

i think this is really grate if it work out


So there's been some great discussion in the last 6 months in regards to reviving TS is some way shape or form. The super popular X275 Class has come up time and time again. Darcy Cummins put a tremendous amount of effort into making something happen with less than stellar support. Roxy from Parts Connection has also expressed interest in trying to help make this happen. I’m still getting PM’s and emails about the topic. Here’s my take: If this deal is going to happen and is going to have legs to grow I believe we would need to adopt the X275 rule set that John Sears runs that pretty well everyone has adopted. Like Darcy mentioned in the other thread, this rule set would allow local racers to travel to other races without fear that they are not rule compliant.
For this to work, the rule set would need to be adopted with little or no variation. I don’t think we could allow certain items just because that’s what you’ve got or what you ran in the past. We’ve made the mistake of going down that road in the past and all we end up doing is hurting you guys. I’m going to contact Darcy and Roxy and see if they’re still onboard with some sponsor support and if so I think we may be able to make this deal fly.
Here a link to the website:

Thanks again for the support John, we're looking forward to X275 in Canada!
Our home track is giving us some grief over bringing another 1/8th mile eliminator (we switched our 10.5 class to 1/8th last season) to their 1/4 mile facility. I have a meeting scheduled with the track owner to resolve the issue but otherwise we're full steam ahead for 2011.
The Mike's are good Jimmy, how 'bout you? Work, family, and the OSCA keep us hoppin' year round!

We'll keep everyone posted on our progress!
