  • Tyre pressures must be right all way around. If the engine is as heavy as you say, you should probably go for the 2.2 numbers - 1.6 bar front, 2.5 bar rear.

1.6 / 2.5 bar? The manual says 1.6-1.8 front, 1.9-2.1 rear. I do 1.8 and 2.1.

The front end has to be quite soft to cope well with the lightness of that end, especially on the 2.2. Since your seem to have about the same weight distribution as the 2.2, you should go by those numbers. So I don't think you should follow the 1.6-numbers.

  • Since you have replaced the rear springs and anti-roll bar, you should also uprate the front end to 2.2 spec, especially the anti-roll bar. The anti-roll bar is a lod transfer device and it transfers loads between tyres during cornering between the left and right tyres, as well as the front and rears.

What is "2.2 spec"? So a thicker anti-roll bar. What else?

Torsion bars, i.e. the springs. I don't remember if the dampers are different too, but if they are, then uprate them too.

But start with the tyre pressure, I have received a few good lectures from Roy Gillard about this Smiley In one case, when his car was new, he almost lost the rear end in a roundabout (if I remember him correctly) because tyre pressure was set incorrectly by a garage. Getting it right (1.6/2.5 bars) cured the oversteer tendency for him.

I don't know what is wrong with barts setup

ik have koni at 75% on my murena, with shortened 2.2 springs. i have a 1.6
in front i also had monroe. and original torsion bars. i have seen barts murena. and when i push the back down, it is as stiff as mine.

I had an excellent road holding with my murena, accept the front was leaning to much.

now i have koni's in the front, the roadholding is even better.

can't carjoy help you bart?
