Looking for rear springs with 75mm inner diameter and longer than 320mm

[notly1988]

Hello,

I convert a Polo 86C to electric drive.
Since the box is now a bit heavier and deeper, I would like to balance that with stronger Ferdern. Front are Golf 4 springs in it, which fit perfectly.

For the rear Passat 35I springs fit, but all I had found so far had a wrong measure.

I'm looking for springs with 75mm inner diameter, wire diameter around 10mm and a length of more than 330mm. The springs must have a constant diameter, so do not get to receive a small winding.

Is there in the forum specialists who can help me there ?: Help:

Nice rest weekend,
