Event Release/Photo by McCarthy Photographic

Charlottetown, PEI. The Rules package for the Maritime Street Stock Showdown occurring at Oyster Bed Speedway on Saturday, June 24th have been released.  The information can be found here and on the event website www.streetstockshowdown.com .

Race Promoter Tom Nicholls of BPMS noted “The rules package should provide for parity amongst all participants. In deriving at this package we as a group looked at what was the easiest way to implement a rules package that would require the least amount of work for the drivers. In the end you only have a few variables to work with being items such as car weights and gears. We have to remember some may be racing that Friday evening as well or the week-end prior and after and do not have the time to make wholesale changes in their racing season”.

“I am certain there are other ideas out there but this is the package for this year and it will not change. To be race ready for the event it basically means one night in your race shop, possibly adding weight and/or changing rear end gears. There has to be some give and take to give every racer a fair shake at winning. So we encourage all drivers to work within the rules package and their home track rules package”.

 

RULES PACKAGE

 

  • Street Stock Cars and the Scotia Truck Class.
  • Maritime Street Stock Cars may compete under the Oyster Bed Rules Package – see oysterbedspeedwaypei.com .See adjustments and rationale for such listed below.

Weights

 

  • Minimum weight for any car is 3500 lbs.

Rationale – It is easier to bring all cars to 3500 lbs. It is easier to tech all cars at the same weight.

 

  • Maximum left side weight is no more than 56%.

Rationale- It is easier to add 100 pounds to the left side for all 3400 pound cars to get to 56% from their current 53%. You want more left side weight on a banked track.

 

  • Maximum rear end weight is no more than 48%.

Rationale – It allows the 3400 pound cars to distribute weight where they wish to on the left side of the car with being allowed a 48% rear end weight along with the 56% left side weight.

 

  • Weights are driver in the car and full of fuel PRIOR to the race. For example, the 100 lap race weight allowed is the 3500 minimum pre-race weight.

However, any car weighing substantially less than the average of the other cars post-race may be disqualified pending further inspection.
