Hello everyone,
Im new to this website and so bear with me when it comes to the more or less dumb questions. i'm building a 1/18th model of a sprint car.No particular driver or team,it will be a generic one. Now I'm building this,basically from the ground up but not really knowing what the hell I'm doing in terms of the mechanics of a sprint car.I've always liked watching them at the track and so that is why I've been fasinated by the sport of open wheel racing.
So now with this in mind,I need all of you guys help in building this kit!I'm starting to scratch build the rotors but I'm having a problem with a couple of things and here are some of what I'm talking about.
1.Can anyone please tell me after I've built the rotor and calibers where does the wheel hub go?
2.Is there any detailed diagrams for the break systems on sprint cars?
3.Based on the model instructions,there is only 1 pair of breaks and that is on the left side,should'nt there be breaks on all 4 tires?
4.Now as for the wheel hub,is that the part where the bolts are attached to?
5.If so,what is the size of those bolts as well as the lug nut size?
6.Does anyone or any website have good quality photos of a sprint car system?
I guess this will be all for now,I hope you guys can help me with this.
Thank you :-)

I too at one time was fascinated by sprint cars and their simplicity yet very advanced and technical in some areas, without growing up around them or never having one close enuff to hold (aww love) or put hands on mind you . it can be relatively overwhelming as to what goes where and "how does that work" comes to mind plumbing systems on the modern car are very sophisticated but once a gentleman gets the hang of it its pretty entertaining watching new fans try understand it. SOOO. anyway I enjoy explaining how this beast eats tires and makes noise and smells awfully good when running Ill see if I can clear some questions for you without going into extreem detail of the mechanics (Im terrible at explaining in a nutshell but ill try) shortly after being "just a fan" I became a crewmeber, then my chance came to purchase one in pieces and I had to assemble it from the ground up, I luckily had a local racer that was a great mentor and helped me through the phases of the build, besides, he sold me the car, Now ive driven several rebuilt them after crashes, junked a couple,totally rebuilt them in the off season ,ect so ,every racer on here can tell you what size wrench/or tool they need for exactly every fastener, bolt,pin, clip ect a good book to purchase would be Steve Smith Sprint Car Chassis technology, you can reread anything you dont understand and hopefull get aquainted with the items , its a pretty basic book and maybe deals with the Era car your building.. Mind you Todays racers look for a edge some brake syastems ect can be very different from one to the other, same with cooling,fuel,oil,steering, But the Mid 90"Gambler type car is a good Platue of what is typical of a sprint car if there was to be a Generic type car,
1. wheel hubs are a (now direct mount type configuration) some call them a Wide Five type deal , the wheel unbolts from the Hub on the frontend leaving the Rotor attached to the Hub on the LF of the car , 90's ish they utilized a six pin configuration which resembled a typical wheel on a passenger type car, but only used 3 lugnuts,
2/3. brakes commonly use a "inboard brake" on the rearend, which uses a "live tube" much like a gokart axle the 3" dia tube rotates there is no Axle located inside the large aluminum tube you see on the rear, very strong and lighwieght, some racers will occasionally use a RR brake much like the one and only caliper youll see located on the LF, there is no RF brake that wheel is just along for the spin.the rear tires obtain their brakeing because of a locked live axle that has no slip the ring gear bolts permenatly and solily to the rear axle thus two wheels can be operated by one caliper (see, simple isn't it!)
4. hubs are the center of the wheel , again this piece commonly remains on the car on todays conventional sprinter when the "outer " wheel is removed, NOW on the rear wheels the hub is splined it remains on the wheel when the wheel is removed from the car, the axle drives the rear wheels by use of the splined rear axle.
5. a direct mount style hub used 3/8 " coarse studs 5 of them located on the hub, top teams will utilize titanium studs to reduce rotating weight (aww but its so sophisticated now!) the use of titanium is excellent, But pricey, it can be found almost everywhere on the Pro's cars..
6. Call Speedway motors, request a catalogue , there is excellent photos of parts and pieces you can paw over to understand how it all bolts together, besides next time you see a crumpled wing, and the driver is pissed, you know he just spent about $1000 dollars! and there is the simple part again!, it just simply takes MONEY!
www.speedwaymotors.com 1-800-979-0122 tell them youll take one of everything, ill email you my address to send it too. good luck with the model, itll turn out excellent im sure, Sprincars!, their a beautiful thing!

shoot me an e-mail when you have a question. [email protected]. been going to the races since I was four in 79 . I race my dad raced. we had a shop for almost twenty yrs where we assembled sprinters and sold everything to bolt on them. we even manufactured a few pieces including the frames. good luck in your new addiction. theres nothing better than climbing in that baby.

You can also just GOOGLE Sprint Car front axle. I found several pictures that show them on line. As well as Sprint car brakes.
As far as Brakes go as was stated Left front only. Flex line from the caliper to the frame then Zip tied to frame up to motor plate. Then zip tied up frame to the master cylinder.
Left rear inboard brake is from the same master cylinder. Brake line is zip tied to frame down by the rear end then a flex line to the caliper. If you run a Right Rear brake you put a T where the left rear flex line come off the frame and zip tie the line across the frame to the right rear where there is a fex line to the caliper.
On pavement you run all 4 brakes, as well as a brake biaser so you can move the brake power to the front or rear depinding if you are tight hitting the wall with the front or loose hitting the wall with the back when braking into the turn.
Also the best thing for you to get the Steve Smith books with Jimmy Sills as the man doing the telling. Is just type in http://www.ssapubl.com/productList.aspx?track=DirtTrack&car=Sprint The DVD is the better than the book it has video of a sprint car and how you set it up.

Hey dirtdevil,
Thanks for the info., and the quick reply. if I need any more info I will have to look you up,deal? lol and as for that book by steve smith "sprint car chassis technology" do you have that book?If so, I would like to know who is the publisher and what is the ISBN# so I to can maybe buy it.
Thank you

do have the book, it has been years since I looked anything up in it , and honestly, its proubly under a bunch of sprint and midget magazines, (or openwheels) and or a few playboys lol (if I start look now I may never find It.. lol im easily distracted) if you find the Speedway catalog it is listed in there specify to speedway you want the "sprint " edition otherwise you'll get bombarded with IMCA or Hotrod stuff, which is fine too..if your into that type of car ect. like someone posted on here Google the parts your looking for, much of what your looking for is right here only a click away. keep digging. I find most good and not so good information on the Net. Google Images might be helpfull for your build. If I lived closer I would have no problem with you coming over and looking over the car, Im pretty sure most racers don't mind visitors in the shop if everything is operating smoothly,explain what your building, get aquainted with a helpfull local,buy his shirt, become a fan, be good to him when his luck is down, cheer for him like you were on his wagon from day one when his luck is good. you'll have no problems getting generic info from him, most of us enjoy, new fans..
