Can anyone tell me what sort of damper this is because I need something like that to stop my RV8 from having a sideways rocking motion and I haven't even started the engine yet. The original Luego rubber mountings seem a little soft. The build is only weeks away from completion now.

Is it def a damper? It looks like two bits of tubes sleeve-welded together.....

Possibly a modified Austin Mini (to distinguish from the fake bmw mini) engine stabiliser bar.

They are NOT dampers.
They are anti roll bar drop links.
Cut, shortened and sleeved, and welded back up.

Mini Engine stabilizer was another earlier version, but same idea / simmilar part.

I would also weld a tube into the square chassis section for the bolt, as drilling a hole that big in it, will weaken it a little.
You really want two of these bars one on each side. Bear in mind the direction of the stresses from the Engine and especially if you have more than the std 3.5litre Rover engine

I have found this on the net after some googling at this website. Seems a little expensive though in the States $109.00

Not sure whether these would be too stiff

Yes they would be too stiff. They are hard eyes, and the cut drop links have rubber eyes which allow an amount of flexing, which is needed.
Believe me there is a LOT of torque in the RV8, and you need a bit of give and take in the mountings!


EDIT:
They Help prevent the engine from rocking and knocking the exhaust pipes into the side panels, and damaging them, and the exhaust header pipes, which aint cheap!

these could be converted to have rubber bushes fitted / grafted on, then a degree of adjustment can be made to fine tune the damping

True... but £50 ($109) versus £3, and its no contest!

My V8 and gearbox are mounted solid on to the chassis with a solid torque arm - no bushes or damper.

No problems at all in fact the gearchange is much better as there is less slop.

Before some bright spark suggests it no the chassis has not cracked, its a lightweight chassis and the engine is pushing out 400ftlb torque.

The rubber mounts and dampers are designed for limo's we are driving sports cars so dump the rubbers and save weight
