indeed.. but riding the rear bumper and spinning the tires of the line are two different situations..

riding the bumper = damn hookin
spinning the tires = pretty self explained..

Anyway. thats my point of view.. and as ricey as it may sound.. i would rather drag the bumper than spin the hell out...

Spinning only hurts the ego, dragging the bumper hurts the pocketbook and MANY hours of work

Point was that they both tank the **** out of your e.t.'s

And both are not a desired outcome after doing your suspension work...

But riding the bumper will tank the **** out of your car too!!!

In all of our testing with different T/A's the short one works for most guys. Now you start makeing some power and things need to looked at differently. Our short T/A was tested on Super Street and Super Stock type of cars. Where you want the front end to jerk up out of the lights when they leave. Like someone else has stated it makes the car hit the tires harder to make it leave. Most of these cars are shall we say Lazy at the starting line..So with a good shock combo and a short T/A that is how we get the car to react..

The cars that have drug the bumper have been competitors pieces. If you set my arm correctly the car will hook and go BUT as everyone knows the only way to win is lean on it. So at times the bumper is there.
Not sure why you are getting pissy here. I was actually sending a customer to ask you the question. You are the sponsor here. Everyone praises you for your work. I don't have to praise you but nothing was meant negatively by that post. Go have a beer or 12 man.

I thought getting on the bumper meant the car is dead hooking? If the car doesnt hook it doesnt stand a chance of commin up? The reason it gets on the bumper is the lack of wheelie bars. If Madman's T/A's are as good as they say....... maybe he should sell the T/A's with wheelie bars as a package or include a disclaimer: May cause bumper damage, Use at your own risk. Not responsible for damages or neck breaking launches.

You can keep a car with **** loads of grip and power from cumming up... unless you make it front wheel drive or Tie the front end to a rail on the track like dem Jr. Dragsters at Speedzone!!!??

Makes me feel all warm and fuzzy inside.

You do not want a car to 'dead-hook'. In order to achieve maximum wheel speed you will need to turn the tire over. 'Dead Hooking' will stand a car up on a bumper or get it on the wheelie bars so hard you will unload the tires. A certain amount of wheel speed is to be encouraged to achieve maximum ET.

This is true. If you talk to most serious racers they will tell you that putting a car on the bumper isn't exactly a sign of a good working suspension but more so of a lack of power out of the hole. Like Ben said a car needs a little bit of tire "spin" or rotation at the line to make the best ET pass.

That is not true for a small tire low HP car.
