I have two questions regarding the proposed TEXAS Street Stock Championship Series.

 

1. THR and HMP rule differences, what will the official rules be?

2. If the following adjustments are allowed on leaf spring cars, why aren’t coil spring cars allowed jacking bolts? Seems to me that these adjustments are a type of jacking bolt, it's not as if jacking bolts are expensive.

I didn't include CC San Antonio, since I wasn't sure if their were any dates schedualed for those track. :D

This is purely a guess on my part, but since HMP doesn't have a SS class (they run hobby stocks), I'm thinking the rules will be closer to the THR rules.

 

I think these races were aimed at the THR Street Stocks, but I'm not certain. That's just what it seemed like when I listened to the announcement on the M-zone show last weekend.

 

BTW, the THR cars cannot run leaf spring sliders, but adjustable shackles are allowed this year.

You're right, but if you compare the rules from both division and apply the more liberal rules you get a good amount of HMP rules. They might be called hobby stocks, but when compared to the THR hobby stock rules they are more like street stocks.

The HMP Hobby Stocks are very similar to the Houston Dirt Hobby Stocks. This is the first year and we are learning, but we felt we could attract more dirt cars from houston then cars from out of town.

I’m not disagreeing with the rules, I heard something about the hobby stocks coming from a dirt track. I believe this is a good move by HMP, in my opinion they desperately needed a entry level class. The hobby stock classes at most tracks across the country attract the highest car counts and usually provide the best racing.

 

Unfortunately, like the late models the tracks can’t seem to play nicely together and have uniform rules that allow racers to race on there off weeks and the big end of the year races at the various track without spending additional money for changes to make their cars legal or competitive. :D
