      Amazing springs

      I had these fitted yesterday at Mountune HQ. First impressions are good. Pogo effect severely reduced and car feels much more comfortable over sections of the road I know would be jarring before. Sports setting on the suspension is still harsh however I feel is much more usable & a viable option now when going for a spirited drive. Steering feels slightly heavier too (probably just placebo) and I’ve also found the car has even better handling now than it did before. I have noticed the quicker you go the less difference there is to the oem set up but on a normal motorway cruise or a quick B road blast the car is transformed. Overall very happy with the purchase, will wait a couple of weeks & get the car in for hunter alignment, not that I’m expecting any issues at all in that regard! Just the intercooler left to go then modification is done (probably!). Thanks Fred, Ryan & the rest of the mountune team, see you at Ford Fair!

      Sport spring kit -RS

      Easy to fit, Car stance now looks even better, can’t say I’ve noticed a big difference in ride quality but then I don’t use the car very often
