I've changed my prefacelift shifter for a facelift one, it was pretty easy, just remove the old one, twist the plastic rod that the button hooks on to around 90 degrees, stick the new shifter on
Little before and after:
Most RS style grills should come with brackets to hold the sensors, they need to be flush with the surface of the grill and the number plate needs to be high enough above the sensors to not trigger them
It's a pain in the *** to do, the flange bolts are not the easiest to get to, ideally need some cut down spanners or banana spanners Can't comment on drone though, i have milltek ones, they have a bit of drone in a certain rev range but easy to live with
The aftermarket air setups are great providing they're set up properly and maintained well, that's where most people go wrong! Oem air suspension does seem to have a lot of issues but I've never had to experience it.
I have 3p on my S4, no regrets!
