under slung,..over run????

[ALF401]

This question always make me laugh....how many of your race cars don't have top rear frame rails becauase it has under rails? It's not a question of overraill vs under rail. It's to under rail or not to under rail, ive never seen a DLM not have top rear fram rails.

Here at Warrior in the mid 2000's we did build ea style a lil differnt if it was a"overrail" car it had larger diameter rear rails than if it was built to have underrails then "overrails" were smaller. But sense 2007 all of our cars have the same diameter rear main frame rails and under rails were a option to our customer untill 2010 when they became standard.

So look at it that way to under rail or not to....

So all warior car new than 2010 are underslung cars??

It was late 2010 when warrior stopped making it an option. So they maybe a few 2010 cars that don't have under rails. And as far as bolt in we have done 1 car like that but the underraill never got taken out.

we tried the bolt on under rail on a blue front rocket, i didnt really like the way its setup but we did notice a small difference in how the car reacted to change on the track and the way it drove and there was a small difference when we checked it with changes on the scales. your average driver will prob never feel the change but a highly experienced an skilled driver will. i think the most change we seen on the scales was around 4-5lb's change on a adjustment between with the rail and without, so thats telling me its def taking flex out of the car. i believe there needs to be some flex in a dirt car, if there wasnt it wouldnt really leave no room for errors or misjudgement in setup and i dont think the car would work right without any flex, but i think rearend is a place you dont want flex to be excessive. its also pretty amazing to see the difference in flex between one manufacture to another. you can definitely tell a difference in the quality of the chassis. most people know who makes the fairly popular low quality car now days its crazy the difference between them and a high quality chassis.

All dirt cars have some flex in them, they have to to be able to work. A rigid car on dirt doesn't work well, don't beleive me? Ask GRT how the computer car worked out for them.

We run a Lazer Chassis and our came came with an underslug setup that is removable but we have found great success with it. We removed it once but wasn't pleased with the results so we put it back in. It does stiffen the car up which our driver likes. Only problem we had was an incident where a guy got into the right rear on a restart and it bent the underslung into the right rear tire and cut the tire down. It was an adjustment tab that we never used so we cut it off with a torch and have had no more problems!
