Just by measuring the gap between each wheel and its adjacent trailing arm, and calculating the adjustment to get the axle central – welding some thick washers to the mounting bracket that fits on the boot floor, and re-doing the bracket hole. This was in preference to re-doing the boot floor GRP and redrilling the holes in the boot floor. The only difference introduced by the springs is if the panhard rod moves by rotation from the horizontal position, which of course it will do when the suspension wheels go up/down anyway. Arguably (if the measurements are taken when the panhard rod is horizontal) it could be prudent to adjust the panhard rod a ‘little long’ because any suspension movement up/down will tend to effectively ‘shorten’ it , thus moving the axle towards the right. An other (more accurate/heavier) way would be fit a watts linkage, which will keep the axle central. At the end of the day from (my albeit simple) calculation it appears (ignoring rubber/poly ‘squash’) there is only about 3mm ‘movement’ due to panhard rod during suspension travel (someone will maybe prove me wrong?)

I guess you adjusted your axle position by moving/modifying panhard rod mounts mounts? For me an adjustable rod (diy or buy) seems a better way to go particularly as I am likely to be experimenting with different rear springs which will necessitate tweaking the rod length.

I did this on mine, and the only bushes I could get were poly, so they will be also fitted.. martin Sent from Mail for Windows 10 From: [email protected] Sent: 03 November 2020 12:40 To: Quantum Owners Group Subject: Re: [Quantum Owners] Saloon rear ARB mounting hardware £12 is certainly cheap for a BMW part! Will be interesting to see how this looks when you get it all installed and of course how it performs. Pretty sure I will need to follow a similar route My rear (suspension that is) ) needs a good working over - needs shorter springs (the ride height is way too high - the rear has the 4*4 look which seems common on Quantum saloons) - needs an adjustable panhard rod (axle is quite offset) - needs new trailing arms and poly bushing all round....

I found it by lots and lots of picture comparing on the net, then took a gamble on the 12mm which was just £12 delivered! I have designed some extension arms to go onto the original ends , this will offer adjustability and reduce its torsion rating.

Can I ask how did you arrive at the BMW bar solution - trawling through scrapyards or did you find some reference material regarding bar dimensions on different cars? I started searching by just by looking at photos of various bars which have similar shape/proportions. Mazda MX5 front was one candidate although I haven't measured one up yet.

Anything over a few years old will possibly be difficult to obtain. BTW how did the Land Rover servo fit on the Q03?
