Twisting drive shafts in two?

[carowner73]

The crush zones are not built into the chassis, they are built to keep the chassis and driver from bending in the event of an impact.the chassis can be super rigid and still have plenty of crush for a short track. the chassis that is rigid is very consistent and setup dependant, some flex is desirable for touring type cars because you can get the setup closer quicker with less precision. the rigid racecar is preferable for the weekly racer competing at the same venue, once you hit the setup the car repeats week after week, but it may take longer to find that sweet spot.

All my cars are built with 12 to 14 sticks of tubing and are super rigid and setup dependant, I can race my car at a track 1 time and then go back a year later with the same setup and get the same results. I let my shocks and springs do the work, not twist my chassis all to pieces. I have yet to build a racecar that didnt make 10 seasons.

The more a chassis flexes the larger "Sweet Spot" it has for setup and is less forgiving of track conditions. A rigid chassis is harder to get setup and MUST change with track conditions. This is why the GRT computer car failed. They designed and built a car that would not flex and you could not keep the car setup for the track as is changed from the beginning of the race till the end.

A top dirt late model chassis builder several years back built a chassis that was built to flex so much they planed it to only race about 10 events before it would need to be replaced due to flex/stress cracks.Only put one setup on it and ran it at 9 events and it was first or second every event and then they swapped out the chassis and did it again for another 10 events.

Crash zones are built and designed into a car to allow the car to absorb impact by bending during a crash rather than transmit the force to the driver. The are SPECIFICALLY built into the chassis to allow the chassis to bend.

somewhere around 01-03 rocket made some cars out of a different tubing (i believe it came from a different supplier or something along those lines) and the cars wouldn't flex, most drivers hated them, a quick fix was to cut the cross bar out of the center of the halo to try and add some flex, anyone that ran the cars on bullrings struggled, some people had luck with them on big momentum tracks... and further proof of the lack of flex... it is easier to find a used 01 rocket than an 04 lol cause they are still around

We arent talking about a late model, a late model has absolutely zero influence on a street stock builder. The two have no comparison as to the way they are designed and built. Noone racing a street stock should give a crap what a late model has or hasnt done, period. If you want to race a throwaway car in street stock then you better have a big bank account or enjoy building new cars every year. I race against wanna be late model guys all the time, most just get tired of getting there asses out ran and move on up to late model, this is just before they go broke and quit.

My point is if you know setup, you will make it a lot longer with a rigid street stock than a throwaway car. If you reread my earlier post, you will see I said the touring guys prefer a car that flexes, this would be referring to most late model guys and a only a few street stock racers. I have yet to see a late model weigh 3200 lbs and run a street stock race, so it is hard for me to compare.

Oh yeah I almost forgot, the bigger sweet spot is bull. The sweet spot is about domination, you cant dominate a track if you are touring.You guys love to get on here and compare apples to oranges, tell everybody what you got is the way to go.

I like my cars stiff, you like your throwaway, we will probably never race, so what does it matter. My reputation speaks for itself were I am from, yours probably does too.

A chasiss is a chassis and good design basics fit if it is a 4 cylinder, streetstock, modified, latemodel or Nascar. A proper built car can flex and NOT be a throw away, there are MANY late 90's late models and modifieds still running and winning.

I worked for several years building cars for a company in Florida that won championships on dirt and asphalt from 4 cylinders to Hooters cup Sportsman and modifieds and they ALL had built in crush areas and they all had built in flex points.

The "sweet spot" I was refering to was what the chassis likes as a setup for a track. Oh and you can Dominate if you are touring. We won at a specific track EVERY time we showed up at a track even against the locals so even if you are touring if you can show up and win every time you pull in, that is domination.

My old green car was a battle tank, it may have still flexed but WAY less than most and it was good to go on ALL tracks all the time with my set up.

My new car I bought was lacking in a lot of bracing departments and with the same set up it was marginal at best and as Ive added bars in the middle to tie the x to the petty bar to the halo and added a engine bay cross bar etc. The car has gotten much much better. It still doesnt transfer weight like my old car or tip up on the rf like my old car but its much more rigid now and I could tell the difference each time I added another brace.

I think the flex it has now comes down to the lack of welded seams on the frame other wise the two cars are almost identical now.



LAST POST on this by me. I speak of my experience as its going on with me right now.

You are an Idiot and have proven it over and over, you have No idea who I am and what I have done. I have not posted one time on your post in weeks which you asked, so you have to try post and try to start by showing your lack of knowledge about me. Again you have zero knowledge about anything I have ever done in racing and I am not here to try to prove myself to anyone so quit trying to start something you are kinda like Hemorrhoids, you think they are taken care of and then you flare up again!
