Put my hand up at side of shock, and does appear to be some sort of spacer / extension at top. Thinking about it, surely if spring length is reduced this would allow drop required (approx. 35mm) as sizes on diagram are with car unladen (does drop approx. 25mm when sitting in car). I presume as long as new spring weight is correct would still have same travel with lower wheel gap ?
Oh the joys of kit cars. Thanks Calum. ________________________________ From: quantumowners@googlegroups.com <quantumowners@googlegroups.com> on behalf of Jim Hearne <j...@quantums.info> Sent: 30 March 2017 13:23:14 To: quantumowners@googlegroups.com Subject: Re: [Quantum Owners] Lowering springs for my 2+2. From: calum mcpherson Sent: Thursday, March 30, 2017 1:00 PM To: quantumowners@googlegroups.com Subject: Re: [Quantum Owners] Lowering springs for my 2+2. Afraid i’m pretty sure that’s the higher rear spring and shock mounts. To be sure, check at the top of the rear shock, you should find an extension screwed to it. They used specific Quantum rear springs to make up the extra length. I’m not sure why the early 2+2 were like this, i guess they did the moulds and then realised the car was just too low to be practical. The front end they could change by modifying the spaceframe, the rear had to wait until they modified the moulds. Jim Attached rough diagram giving sizes and pic of boot showing strut top, measured rear spring sitting unladen at about 250mm.

Too long since i looked at one of the springs to remember the length. But, a picture of the area around the top suspension mount in the boot should tell me which version it is. Or, what is the chassis number ?, mine is 99 and has the high mounts.

Thanks for the prompt reply Jim, I haven't a clue on the rear mounts, is there a rough length of spring that would indicate which I have at rear or front for that matter ? I don't want to be buying and fitting std. XR2 springs only to find I still have the same problem, but possibly a harsh ride too, as I have read that std. XR2 springs are too harsh for rear anyway. I have attached a pic (I think), with new wheels fitted to give you an idea of car, Thanks. Calum.

The 2+2 already sits lower than the donor Fiesta for a given setup, the XR2 was around 20mm lower and lowered XR2 spec springs will be another 30 or 40mm at least. That's why Quantum recommended their red springs at the front and 1100 ((taller than XR2). As a first step i would just try standard XR2 spec springs, not lowered ones. One thing to watch out for, depending on the age of your 2+2, the early ones (up till past chassis number 99 at least) had rear spring and shock absorber mounts on the body that were about 60mm too high, Quantum fixed this with spacers on the top of the shocks and extra tall rear springs. If your car is one of these then you will need to compensate for that on whatever rear springs you get. My 2+2 has coilovers on the front and standard XR2 rear springs, but mine has the high rear mounts. So i've effectively lowered it around 80mm from the Quantum intended spec, it is too low, i have to drive across most speed bumps at an angle and even then they hit the engine crossmember or exhaust. And i can't use it to go to work as the uneven B roads cause similar problems.

I was going to change springs anyway, but now have brought this job forward as not looking as I want. I understand that the manual states 'Quantum red springs' for front and Fiesta mk2 1100 springs for rear, however when looking at lowering springs, most seem to be a standardised Fiesta mk2 set up , most covering full range excluding XR2 !!!! Anyone got any experience with lowering springs , any recommendations would be great . Car has std. XR2 engine set-up, thanks. -- -- You received this message because you are subscribed to the Google Groups "Quantum Owners Group" group.
