I know this is brought up alot but I would like to know if you could design your own chassis some of the things you would like or change. It seems to me most chassis are the same and nobody tries something different. things Im talking about are long wheelbase or short wheelbase and why. Wide or narrow track and why? Is it possible to design a chassis where the percentages are set to not have to add lead. maybe somebody is doing this already but where im from I have seen jet,dirtworks,kosiski,bms,larkins,bigdogs,frc pro,harris and they all seemed to be copys in most aspects.

WELL I'LL START OF THE REPLIES.

THERE ARE A LOT OF CHASSIS OUT THERE AND ALL OF THEM I FEEL ARE BUILT A LITTLE DIFFERENT WITH THE EXCEPTION OF THE OBVIOUS COPIES. UNFORTUNATELY THE MODIFIED CLASS HAS RISEN TO LEVEL WHERE INGENUITY IS NO LONGER. IT IS HARDER THAN EVER TO BUILD YOUR OWN DESIGN, COMPETE AND WIN. THE CHASSIS THAT YOU MENTIONED HAVE HUNDREDS OF CARS ON THE TRACK EVERY WEEKEND. 9 OUT OF 10 TIMES WHEN SOMEONE IS LOOKING TO GET INTO MODS THEY LOOK TOWARDS THE CAR WINNING AT THEIR LOCAL TRACK. IT IS SIMPLY EASIER TO AQUIRE A CAR YOU KNOW WILL WORK THAN TO SPEND TIME ON A BRAINSTORM AND HOPE. I MYSELF AM PLANNING ON BUILDING A CHASSIS THIS WINTER WITH A FORD STUB(REAR STEER) AND A FOUR LINK REAR, WITH A DIFFERENT STYLE TORQUE ARM OF MY OWN DESIGN. I'LL PROBABLY RUN IT A MONTH OR SO, IF DOESN'T WORK THE DW-8 WILL BE READY.

RAIL ROAD TIE REAR BUMPERS GIVE GOOD REAR %
AT LEAST THAT IS WHAT THE BOMBER GUYS TELL ME. LOL

First thing, about all the different makes you mentioned their not all copys of each other each chassis is designed with aspecific a genda in mind,setups, springs,scaling are all different.if you want to build your own chassis be more specific on your goals. left side, rear, what type suspension ,theese paramenters all make a difference in the design of a chassis .back to you later LITTLEMAN

i think that part of the problem is the "throw away chassis" cars are so light that one good hit and the chassis is gone! its seems to me that no one would spend the time it takes, to come up with new ideas, like what you are talking about when you have to worry about being 400# over weight and then under horsepowered! also when dirt works has 7 or 8 guys running house cars and trying new set ups every week it becomes hard to get the same repeatabilty as them. i on the other hand dont mind it ( mostly because im not rich and cannt afford a new chassis). i got an older arrow chassis from up north (South Dakota). it was suposed to be a d.w. take off but they put it on a impala chassis not a metric one. last year we put on a 2-link with a pull bar and seemed to do ok with it. i put adjustable uppers on it this year and finally the chassis is working. the impala chassis is 2" wider in the front than the metric one. i think this gives me a little better corner in stablity than the narrow chassis does.? but i also have to run alot more angle on my j-bar! i guess what im saying is money is a big factor and if you have more time than money it is amazing what you will come up with!!!

There are chassis out there that are trying different things. The problem is that not many racers want to buy an untested design so manufacturers make what they can sell. Shryock R&D's designs all the time for Harris. Only the successful elements make it to production. Hoover makes a longer wheelbase car. Lots of others doing similar work that you rarely hear about because it gets tested before it goes to the production models.
