well what do u think is the firs thing i shud think about befor putting hydraulics on my car?
Hmm...
Here's some thoughts...
What are you are going to do with the hydros, how many batteries, what moves. Depending on that, you would need some reinforment of the frame.
Find a good vendor to buy the parts from, compare prices and service and location.
Get a few books on aircraft and industrial and lowrider hydraulics and electrical. Plan and learn as much as you can before the install.
Get an idea of the tools and safety equipment.
Get an idea of how you plan the layout in the trunk, size cylinders and hoses to the front.
If you're having someone do the cuts outs, find a good shop or someone that knows what to, and, what not to do.
