its 1725 on webers and a 4 branch exhaust

I will be using it for classic rallys it has full cage with diagonal, door bars bucket seats and harnesses skidded exhaust and a hydraulic handbrake in the centre of the car mk 2 escort bilstein rear shockers gaz fronts green stuff front pads on ebc discs poly bushed front end
fuel and brake lines run inside and a sumpgaurd (yet to be made)

if it shows promise but lacks power I will treat it to a 130 bhp coltec engine

to think I nearly sold it a few months ago its certainly gone too far to sell it now !

They better fit this time, think the other ones are slightly out of the cup at the top I'll have a check tonight.

If your using a hybrid prop and English what engine you got in it?

£27 is a good price Luke.... is not much more than I paid for new old stock ones. (£20 each)

They sit in the cups perfectly and would pass mot no problem
They are tight when off the car you only need to compress the spring a little to get the top cap and top mount
I will be fitting small lowering blocks to the rear with a ford axle with lsd
If your not in a rush I can let you know better in a few weeks when I finally get to
Drive it !

Andyb.... I think you could be right about the 9''. Coz with the turret top screwed on there was plenty of slack in there. Do you know weather yours will pass the test with them ones (175lb)? Do they sit nicely in the cups?

And arrocuda... Thanks aswell, tryin to find them at -50mm is quite hard at the minute.probs my heap of **** phone is causing this lol.

Yep..... the keeps hold them in place and even the ones that I bought which were the shortest I could find had to be compressed by about 20mm to wind the turret nut on. With -50mm springs they will be permanently compressed by about 40mm within the strut with no load on them. So even when the wheel is lifted off of the ground the springs are tight in the keeps.

Mk3sceptreluke
I have sorted mine by using rally mk2 escort rs springs rated at 175lb
with a free length of 11" which just fit without spring clamps (can press down by hand)
I think you may have mk1 rs sprimgs which are 9" free length which will be slack when fitted

Std rapier spring are 13" f/l unknown poundage (very soft prob 100lb )
mk2 rs 2000 std spring 130lb 11" f/l arch lip to floor 23"
mk2 rs2000 175lb spring 11" fl arch lip to floor 24"
the extra poundage giving a higher ride height


Gaz reconditioned the old struts for £168 pair inc return postage
I haven't driven it yet but I am sure it will be ok

happy to help with any info you may need to help you decide

AS Jason said.... Ebay is always worth a shot as old stock new ones are often sold on there. If you just want to buy them at OEM prices then you can get them here.....

http://www.europerformance.co.uk/pages/products/search_car/product_sub.mhtml?car=fordsierra;category=loweringsprings

As far as I'm aware there are no build differences through the range apart from maybe the Cosworth 4x4, but I'm not a Ford expert so stick with the standard models and you should be Ok.

If you are looking for a 2" drop you need -50mm springs. You can get a bigger drop than this but they might be harder to find. I acheived -96mm by using a combination of spring and a lower profile tyre in order to enhance the drop and minimise possible clearance issues when cornering.

On the rear axle, as Martyn (UMU) pointed out, you need to be careful that it doesn't bottom out when you have passengers or extra weight in the boot. Easiest way around this is to add an extra leaf to the spring set if it is a problem.
