The final rules for the heads up classes at Bowling Green have not been posted yet. I do know that for TSM at Bowling Green if there were to be any changes they were to be first proposed to me. I did not receive any proposals.

If you are interested in participating in the TSM Point Series, then you must follow that set of procedures/rules in order to obtain points. The rules for the TSM Point Series are posted in the TSM forum on www.T6P.com

Please post the rules here!

Tire/wheel size clarification....

I have a set of Simmons wheels on my car. Rears are 10"x17", yeah I know you old school guys just love those tiny 15" rims...

Can I run these in TSM with a slick that meets the dimensional rules? So a 10.5" wide by 28" tall slick on a 17" rim? This should be a disadvantage to me, can I do it?

Thank you.

Hey Dave.
You might want to ask this same question over on t6p.com as more of the TSM racers seem to visit that site more often.

TSM Information Center - t6p.com - Turbo Buick Regal Resource

I personally don't think it would be an issue as long as the tire measured within the rules specs. Nothing wrong with the high tech look IMO.

[david buschur]

I'll do that Patrick. Thank you.

[slaytera666]

I had no idea Dave raced Buicks too. You learn something new everyday.

[david buschur]

I've done a little Buick racing First time to build one for one of these classes though.

Getting any questions answered is about impossible. Must be to keep the competition down

I think most are just trying to keep an edge on the comp.

[slaytera666]

Well if you race Buicks like DSMs/EVOs, you'll do just fine
When Is Buschur Racing going to start selling Turbo Regal parts?

[david buschur]

slayterra666, Probably will not go into the Buick market. It's got plenty of guys copying each other already. I was quite ticked off today to find some parts I ordered were knock off's of the parts I thought I was getting. What a crock of crap the performance market is. Just looking forward to hanging out and doing some racing. Probably will pick up a lot of tuning work from this though.
