I machined my own AN16 weld bungs and had them welded to the radiators then used the necessary fittings and braided hose. Expensive but works and looks awesome. I also used some silicone hose bought from a race shop here in WI wher they sell elbows of many different degree bends and straights. Also a bit pricey but again looks awsome as its blue in color and easy to use. The silicone hoses are way easier to install!

I see you also use some kind of metal tubing. Whats the purpose of doing that route? Is it cheaper than runing hose that length or ?

Because it is based off the Edge design but not The same as the Edge's Rearend. I have mods that suit CVs with longer travel using longer axles and a shorter centershaft.

Say Doug, can I take the center section on the barracuda and put it in the piranha? I like the way the PIRCV is built compared to in the piranhas.

Why do you think its called a PIRCV???

PIR for Piranha
CV for Constant velocity drive axles and joints.

Havent you seen the home page of the Edge???
There is a Piranha fitted with the PIRCV...

I thought thats what it was called. I just like the double a-arms in the rear. Why are more people going to the double a-arm in the piranha? Is there something wrong with the origanal design?

The Double A arm rear suspension will be a little more expensive as there are more components.

One of the advantages in a double A arm is it allows the wheels to droop, (sag downwards) when the buggy is unloaded.

This means in situations of hard cornering the inside wheel will stay put on the ground when the vehicle has some body roll.

The amount of droop depends on the design, but the idea is to keep the wheel either upright or slightly into negative camber.

You never want a situation of positive camber as the wheel could tuck under.

Droop also keeps the wheels under traction on bumps & hollows.

Double A arm also has the advantage to be able to design the suspension to control the amount of negative camber during suspension movement.

Negative camber is good for a buggy, it aids in stability.

Single arm suspension moves through an arc & progressively goes further into negative camber.
Progressive camber change is also good, but with a single arm there is going to be a limit to suspension travel as the wheel will start to become horizontal.

Double A can be designed to have the amount of camber you want for the job at hand.
It’s also a stronger setup, the pivot points are spread over a larger area.

This aids in absorbing torque reactions from the drive shafts & spreading suspension forces into different areas of the chassis structure.
