MX5 shock bearing question

[jason 82]

I am about to place an order for some Gaz shocks from rally design, & I can't remember what size bearing/Bush I need. I think it's 14mm in the mx5 & 12mm in the Sierra. Does anyone know for definite please ?

Hi Jason

I believe mx5 are 12mm not near car tonight so can't measure but almost 100% sure.

What's the price on Rally Design shocks and springs? I ask as i've just been looking at the Protec Haynes kits here at £547 for shocks and springs:

Thanks Gary. JPS, they are really cheap. £260 ex vat for shocks & springs. The shocks are Gaz ones, come in 1.9 or 2.5 I.d with an option of bearing or Bush shocks. The variation of springs is brilliant as well! I have previously used these on another project & found them brilliant !

Rally design catalogue page 71 in the 2018 catalogue. There is an online catalogue, the springs to suit are on page 69. I have tried uploading a picture for you, but I can't figure out how to upload them sorry. Www.rallydesign.co.uk hope this helps !

Hi I got mine from Rally Designs.
Just stripped mine down to clean everything up and when I removed the shock from the wishbone at the rear, it seems wobbly on the bolt at the top mine has 12mm bolts but the bushes in the shocks is quite a loose fit, same in the wishbone bushes, never really noticed before, they haven't worn as the car hasn't been any where but they don't seem right to me, anyone know if they should be like that the holes in the suspension brackets as supplied are all 12mm
But the poly bushes are definitely a bit bigger.

From what I gather the bushes are generally made as per the book, which is a 12.5mm hole ( some places do make them with 12mm holes) this could explain the 12mm bolt Being a bit loose.
You could ream them out to 12.7mm which would then fit a 1/2 inch bolt.

Hi I have just measured them in the shock they measure 12.56mm and in the poly bushes they measure 12.3mm, if I reamed out shock ones to 12.7mm for half inch bolts as you suggest I would have to enlarge the mounting bracket holes which would be very awkward especially the top shock mount at the rear, do you think it matters to be that loose in the shock mounts? or should I get new bushes at 12mm.
