Building Electric Drag Cart 101

Yall are right, I'm an off road guy. But I was just thinking about the stability of a lowered or modified long travel over a stocker. Its like night and day.

You guys are know more about racing than I do. Since I'm dabbling in the electrics now, I'll just watch and take notes.

I go along with COPB on the "I" beam for front axle, and you must be able to adjust Caster and Camber as needed easily.
I dont know of any "STOCK" components that I would feel safe with at the speeds you are looking for. Definitly much larger Spindles with HD backing to take the stress.
I am real suspicious of EZ GO spring mounts for this kind of speeds again. You should use adjustable springs and shocks for safety sake.
Some type of HD wheels and of course high speed tires, even some auto tires are not good for the high speed used.
I feel that some type of HD shielding should be around the motor and very much so the axle that you use. ( I dont think that the stock differentials that are available for Golf Cars are safe enough for your use?) I know that we have all used stock parts to save money and ease of installation BUT, after loosing 2 relatives to stock parts damage I think something on the order of what is required for NHRA drag racing would be good. I have seen too many parts come up through floors or out into crowds to not want some kind of protection? Thats my 75 year old 2 Cents worth??
Good luck on your project and I hope you keep us posted with photo's along the way.
 
DMS,
Thanks for your post & your concern. This project has been 3 years in the works. I have had several Mechanical Engineers look at this project from one end to the other.

This cart will be safe, fast & a EZ-GO. The black Club Car in the pic's turns 50 mph in 12 sec in the 1/8 mile. With stock gears. There is alot of speed
left in this cart.

The new cart will be built rat here, from start to finish plus its frist run on the drag strip.
 
Another slight problem. This is a pic of my 72 volt motor. Notice the space between the right of motor & the shock. On the new motor the shock will have to be removed & relocated. Are will it. How much of a suspension would I need. I was thinking, leaf spring's & bump stop's.

You would have to have very stiff springs. Shocks do not add support, they dampen the bounce so the cart doesn't act like a yo yo.
 
Actually these are 2 of a 4 leaf set up. We buckled the single stock leaf spring. They look like the letter S. Even the 2 leaf springs are starting to bend. I need to put all 4 leafs back toghter.
 
Thought so. I wonder about some sort of traction bars, (I think some folks called them ladder bars) like I use to see on the leaf springs of older hot rods, It kept them from twisting the spring and causing wheel hop(I think).
