Race format and scoring

This will be a single-elimination tournament. Races are one-on-one. A car will move on in the bracket only when it wins two races in a row. Cars will alternate lanes between each race.

The car that wins the final race will be declared the winner. Race host has final decision in all races.

Bracket seeding will be random.


Cars are given a NO + tolerance over the stated weight limit. to account for variance in scales. The weight limit is 60g as noted by the track's scales.  There will be NO + tolerance.  Any car that exceeds 60g will NOT be allowed to participate.  It is better to come in light than over.

Cars that fail to run or fit on the track, or that happen to break during racing, will forfeit their matches. Cars that arrive broken will attempt to be minimally repaired before the racing begins. Cars that break during racing will not be repaired or replaced.

I'd  watch your Zero Tolerance on the weight...we've had the TE Rule in place here at RLD for a reason...scales vary and the surface they sit upon which all can play a part in the weight shown...especially in for thought.

  • Second. Even +/- 1g would give people some more confidence. Spending all that time to build only to get DQ'ed because the scales are different is a shitter. — redlinederby

I wonder what it is about late fall that leads people to want to put American Muscle in that time slot.  I've got six cars going to the RLD event half a month later, so it's unlikely I'll have time to do one for this.  Plus a big family obligation, as I'm driving across the country to help take care of my mom for a bit.  But, I look forward to seeing what other races you come up with in the future.  :)

  • Hey...I've been doing mine since Nov 2017...I've just got more company now :) — LeagueofSpeed
  • Oh, I know. It's just interesting that the same themes come up at the same times of year. How many different Camaro things were held at the same time this summer? It's like everyone works on a similar vibe, or somethign. — GenX_VintageRacing
  • ...very true...I've had the Summer Series planned out 6 years in advance...Summer 2018 to 2023 — LeagueofSpeed

I appreciate all of the feedback. To answer a few questions and let you in on out train of thought let me explain. I come from a Circle track racing background. My dad races, my uncle races. I raced, my cousin races go karts, etc. One thing that I have found is if you bend even remotely on the rules, ppl take advantage. This will NOT occur here. There is a range from 0-60g any entry can be. Just don't be over. When my cousin and I ran a local go kart track we a very few rules, but the ones we had were set in stone to keep things fair and even across the board. The same applies for us in diecast. Don't be heavy. The ONLY rule other than having a car within the specs. 
As to why we are doing American Muscle, well to be quite honest, in the past 8 months that I've been been involved with diecast racing I've noticed one thing above all others, 85% of those involved (give or take) are over the age of 35 mostly older than that. So, for our very first race we chose the cars that WE love. Our second race in November is NASCAR style stock cars and Dec has yet to be determined. It may be trucks, it may be sub compacts we still don't know. In January we may start two mail ins per month. By then we should have two more tracks in the league. I can't comment on too much of those so as to not offend the powers that be but these rules will always apply. From my experience once people understand that you are serious about the rules and Th at they apply to EVERYONE, it makes for better racing and a better overall experience. Thanks for listening and I hope to be racing with you soon! 

Redline Derby has been around for more than a decade...we are the Mecca of Diecast Racing...we've seen this hardline weight rule go south many times...go karts and such can't be put on a scale that weighs in grams...and not everyone has the same scale or weighs on the same surface...the TE Rule is a recognized rule that has been used in Diecast for many...many years...but Good Luck with the Zero Tolerance...

...League of Speed, RLD Event Coordinator and been racing Diecast hardcore for 4 I speak from experience

Case and point regarding Diecast cars and the surfaces they are weighed on...

...same scale...same car...

40g to 57g...same car...same scale...until we all get the same scales and near identical surface...all Diecast Host should use the TE Rule...

  • With all do respect, it is very simple for all builders/racers to have universal sets of scales. This is accomplished by 2 ways. Always weight your car on a hard, flat and level surface. Next use the nickel test. Place a nickel on your digital scale and if it reads 5g you know your scale is true. I am a professional chef and baker. This is the standard way a truing a digital scale. All scales will perform the same if used correctly. Cheers! — MoparMAC

I figured out pretty quickly that the kitchen scales were not appropriate for measuring 60 grams accurately.  In a sport where weight is so critical, accurate scales should be essential kit.  Here is what I'm using:

I'd like to see more details about the track and how races are filmed.  Do you have a Youtube channel?

  • Hello. Thanks for the link for the scales. Yes we have channel on YouTube. Low Country Diecast Racing League. Cheers! — MoparMAC
  • Lol! I'm using the black version. those jeweler scales are nice. Always make sure to turn fans off or turn away from scale! hahahaha! — CrazyEights
  • their channel is low country diecast racing league. nice track. it's quick. — CrazyEights

Simple fact, all scales are not created equal. True you can weigh a nickle but not all nickles weigh exactly 5g. I've tested. My newest scale similar to one shown has had to be recalibrated 3 times since I started using it. Why? Cell phone got to close. Read on the instructions and it clearly says keep it away. It may have gotten to close taking a picture of a car being weighed. My 20 year old postal scale by Royal is still quite accurate. Just no decimal. The 'no tolerance' is a tad much in my books. (TE 2 gram rule has become the sport standard). And it isn't the fact that house cars have a benefit of being dead accurate vs 'come in under weight' not to get penalized or not even run. Yeah, I'll have to think about this one.

I've hosted more races in the last 2 years than just about anybody in Redline Derby or Hot Wheels Downhill Racing Facebook group. Grant you being a hardass wouldn't have garnered me the respect I receive from racers who come to race at the Bayou City Diecast Raceplex. Where you get fair & honest racing on professional grade tracks. Good luck.

Race On & Race Hard!

  • That sucks. I don't do Facebook or I'd join that. — CrazyEights
  • Well, we do post the FB live video on YouTube but that is not live. It’s about 3 hours behind. — FPD_Racing
  • I am so confused? I thought WE WERE ALL CREATED EQUAL? Ops!!! Okay, nevermind.... Your talking about Scales. This is by far one of the best discussions ever. Just because of this controversy, I want to RACE in this one. I suggest we all build a car that weighs in at 50-54 grams and if you go over by 6 grams, your screwed. If you don't you get to race and you have a chance to be the Big Mac on the Hill or the Mac Daddy of the Hill, or the MAC N Cheese of the Hill, You get my point! — RIVERA_RACING
  • That's where you got it twisted,Riviera. Equality is a myth. It doesn't exist. The events of the past few weeks have proved that. — CrazyEights
  • I agree Mike! — RIVERA_RACING

Hi, Just found y'all's channel.  I read the rules.   I have a Shelby Cobra (Larry Wood) white with Carrol Shelby written on the side.  It weighs 36.1g, if this is acceptable to you, this is the car that I will enter for your Oct. American Muscle Tournament.

Thank you for your time, Po'Boy Racing

  • Shelby Cobra works for me, one of my favorites. 36.1 is a little light but is definitely within the rules. Does Po Boy Racing have a logo? If so please send it to us. I'd like to use it on the track I am currently building. — FPD_Racing
  • Please email me at for the mail in address. The cost for the entry is $2. If you would like your car returned it will be At least $5. Basically, whatever it cost to ship to us is what it will cast to ship back. We look forward to your entry arriving! — FPD_Racing
  • I emailed you too. — CrazyEights
