You are responsible for the min. weight of your car depending on what additional allowances are on your car. All cars start at 3100 lbs. w driver. Add your weight penalties up and together you will have the total weight you must be after the race.

 

Example: if you run a 3 link car w/ rebuildable shocks, high rise intake manifold, sheet metal body, w only a portion of a firewall then your weight penalties will add up to 200 lbs.

 

Base Weight Rule 3100 lbs. + 200 lbs. in allowances = 3300 lbs. is your new min. weight

 

We reserve the right to eliminate any gray area rule that is exposed by a competitor at any time. Ask before you do it could say you alot of time and money. 2014 rule package should allow drivers some flexibility. It levels the playing field for those that don't want to upgrade or run certain parts vs the driver's that do. We believe this will make for a much easier way of teching cars prior and after races. We hope our effort pays off for everyone involved in the series as we strive to making the shootout bigger and better every year! Rules are out early this year for your benefit. We will continue to review any neccessary rule adjustments to make the best possible rule package for all involved.

Question. In this post it says no tubular front or rear clips allowed. In the Street stock shootout forum it doesnt say this, it only says no tubular front clips. We are building a street stock and we have already installed the tube rear from the the front clip back. Are we illegal for this series?

Well our two time champion has been on 8inch both years. I think there is an advantage for 10 inch on loose greesy tracks but when it Texas do we have that? Usually only under certain circumstances. However we do have from time to time fantastic runs by guys on 10 inch stuff. Race #1 was won by #75$ Bo Beckner and he is on them. So I guess it depends on who you ask if that helps any.

Do the 10" tires help that much? My purestock engine meets all of the rules for engine package a. I was thinking about putting some 10" tires on and running it with yall in December.

 

i would ask local track you run at if you race in streetstock would it have any affect on racing pure again many folks are leaning toward this bein a beginner class on what class you race not by cost of class oe experience,. jmo

After careful discussion and learning what is becoming available in the shock industry we have massaged the shock rules for 2014. We still are allowing alot of shocks we are now just more clear on what is exceptable and what will require a weight penalty. Please review.

 

We have clarified a few additional items in the rear suspension area as well. Also refer to allowances and those additions as well. Please review.

 

We will be concentrating on motor loop holes and gray areas over the next few days. Stay tuned for any possible adjustments there as well.

Lets make sure everyone understands the 2014 rules are simplifying what we are currently running under from a series standpoint. We are not asking anyone to upgrade or have to change parts. As a matter of fact you may find the rules benefit most more then ever due to the weight penalties that some will be taking on due to how their car was built and the type of parts being used. Get a good grasp of the base rules and then read the Allows that require the adding of weight. You might end up with your car being able to run up to 300 lbs lighter then others. From a track standpoint if a track adopts our rules it allows a track to pull cars from other tracks on rainouts and off weeks. Again drivers are not having to change anything but if they want to they can with a few weight penalties. A racer with these rules have more options then ever before also with the most possible cars. Regardless what some my feel good or bad for anything to work we have to consider the best options for tracks to get better car counts on their normal nights. These rules do exactly that and will give the techmen one set of rules that they can enforce.
