Technical Gaz coil overs

Time for an update! I have now removed the A arms for shot blasting, and I'm going to fit Gaz coil over shocks, has anyone fitted coil overs on the rear? If so did you leave the original spring mount in place?
I have GAZ coil-overs on the front, but fitting them to the rear is a totally different ball-game----MUCH more difficult. I can't really see the point of fitting them to the rear on a "road use only" car. If you do go ahead and fit them, be prepared for quite a bit of "settlement". Also, when my 'coil-overs' were originally supplied, the spring-adjuster-ring was held in place with a 'grub-screw'---NOT a good idea; ask for a 2nd PLAIN ring and a 2nd adjuster-ring spanner. You will also require "helper" springs in order to hold the spring in place whenever you jack-up the rear of the car.

Hi Hobbler I'm not sure why a helper spring would be required, I have been recommended Gaz, I also have them on my Cobra replica and know them to be of good quality. My question was did the original spring mounts remain, or did you remove them, did you have integral bump stops or retain the original stops.
 
A helper spring is there to stop a the main spring become loose and unseated when the suspension is at full droop. If a spring is uncontained at full droop this is an MOT fail due to the risk of the spring not relocating correctly upon recompressing of the suspension. Realistically the risk on a coilover setup is low, but that’s still the law.

I do not wish to be patronising, but there’s a lot of misconception about coilovers and their benefits online. In theory a ‘coil over damper’ shock absorber is just the concept of having a coil spring surrounding the damper, in practice when most people talk of ‘coilovers’ they also expect to have a threaded collar allowing height adjustment.

There is nothing about a rear coilover conversion that would work any better compared to the standard Fiat set-up with a separate coil spring and damper. It’s just how the same parts are arranged. All you gain is the fine adjustment of height with the collar.

In the front, on the other hand, converting from leaf spring, to a wishbone and coilover set-up will make considerable improvement to both geometry and ride.

If you are looking for sporty handling I would suggest getting a front coilover and some sports dampers for the rear. There are various suppliers of lower/stiffer rear springs that fit in the stock location.

Right maybe I should've explained further, they are units that have the double ring to secure the bottom of the spring, I would question why a coil over shock would be assembled so loose as come away from it's mount, but anywho, I appreciate that people will give opinions, if you prefer the original set up fine, in your opinion, others have preferences, reasons for choosing what they choose, I haven't asked for information regarding the front suspension, I know what I want to do there. My question was if anyone has fitted coil overs did they remove the original spring mount, an answer to the question if possible would be appreciated, rather than an opinion. I can always ask for an opinion.

Whilst I totally agree with "Goldenrust", I accept that we have not answered your question. Whilst I haven't myself fitted rear 'coil-overs' (for the very reason that Goldenrust explained) I have fitted new rear dampers and "original pattern" springs. From what i remember of the layout, I would have thought that you would NOT use the original spring mounting points---this is because the coil-over units would be using the original damper mounting points and the original "factory" spring mount would get in the way of the 'coil-over' unit. There was a Forum member (Andrew Harvey) down in the Canterbury area who I seem to remember fitted both rear discs and rear coil-overs---maybe he could give a more educated answer.

I'm not using the original spring mounts, have you not read my post? Try again, come on people, let's not let this forum become a place where opinions take over from answering questions and please look at the questions. I will tell you a bit about me, I will try to use something that is not necessarily supposed to work, and look at how to make it work, this may involve machining or a slight redesign. I enjoy making old engines work better by using new tech, so in short restomoding something to suit my purpose, judge me if you will, there is so much that can be done to continue using and enjoying these or any other classic cars, how people do this is up to the owner. These forums should be to support people, and not say what is unnecessary.

Your original question was---"did you leave the original spring mount in place?" which until you have just advised us that you are not using them anyway, would leave Forum members to assume that you were asking if one would leave the spring mounts "on" or "take them off". I am not judging you, but was just trying to give you a sensible answer in relation to your ORIGINAL query. As I said, I had not personally fitted rear 'coil-overs' but was trying to indicate as to why you would need to remove the spring-mounts. I also gave you the name of a Forum member who had possibly done this modification, as a possible source of advise/information

Hobler why would I use them with coil overs, come on man. The Original question WASN'T considered. I am not going to get into a pointless discussion, I will just say don't presume, because.......
