      Better handling, more composure

      I have installed Mountune spring kit for my RS mk3 already upgraded by adding DSC Sport suspension controller. Adding these springs is an improvement I expected. The car handles noticeably better, with less roll, slightly sharper reactions to steering inputs. Ride comfort has slightly improved over small crests in tarmac. In general, my RS now feels better glued to the road. Height drop is – curiously - noticeable even from driving position (another improvement). What is suprprising is that the difference between Normal and Sport damper settings (from DSC Controller) are now more clear. Ride comfort in Normal mode is totally acceptable now. A big, big plus! Overall, a definite improvement to already good RS mk3 chassis. Now it is really a great driving machine!

      Bobbing along no more

      Excellent I do like the rather fetching yellow. But whilst retaining the normal RS trait of firmer than most, they are more compliant than standard. They have a greater progression & smooth out the bumps & help to stop the RS becoming a 70s throwback (pogoing)

      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!
