Stiffer, obviously. And it likes to followcamber and imperfections in the road more.

Comfort thus far seems to be unchanged. Very happy with that.

Can't comment on hard driving handling, the weather is too grim to try at the moment

Did they calm down the rear floatiness the stock PP springs give?

Reason I ask is because were all either calculating spring rate incorrectly or these springs are actually softer than PP springs, hence why your finding comfort is un-changed.


US PP Springs: Front 165lbs/inch & Rear 728lbs/inch
US Pro-Kit progressive springs: Front 200-314lbs/inch & Rear 800-914lbs/inch (30mm front / 25mm rear)
UK Pro-Kit linear springs: Front 150lbs/inch & Rear 650lbs/inch (25mm front / 20mm rear)



So if we are correctly working out the spring rate the UK Pro Kit is not only linear VS progressive but its also a lower rate spring compared to US GT PP springs.

Of course nobody knows the spring rate for the UK/EU GT PP springs.


Still these look to be a great option for those wanting the lower looks with absolute no change in ride quality, on the basis we have calculated spring rate correct, but two of us have done it now and both coming to same conclusion.

I feel like the rear float is more contained, yes. It settles back to 'balance' much more quickly.

However, these things are always very subjective!

I am a little tempted to try them, just not sure how they would work with uprated dampers and uprated anti-roll bars, could be an in-balance and now I've switched tyres the cars compliance has improved a lot. :)

I have a set sitting here I plan to get into the sales thread this weekend along with a 2015-17 boot liner. No need for either now that I've moved over to the 2018 order

Boot liner will probably still fit, doubt the boots changed AT ALL for the MY18s. Structurally all looks the same, just some panel look alikes.

Your probably right Manders but it's just sitting here taking up space. May hold onto it until I'm able to see if it fits or not. No real hurry to shift it.

The continuing supply issues (in some parts) seem very strange.

A friend here in NL (not on the forums) just ordered a set from the local Ford Store.

Delivered in 4 days with zero issues.
