I picked up my RS on Christmas Eve, early Christmas present for myself. Upgraded from an ST-3. The RS is a mid 2018 model with every extra box ticked and 2400 miles on the clock, virtually a brand new car.
So far I’m loving it although I have just ordered the lower seat rail kit as I’m over 6ft tall, you do sit rather high in the shell seats.
JCR kit dropped original seat set up by 55mm max. If you have ford’s modified seat drop, it’s lower than original set up by 15mn. If you use JCR kit you’ll be able to get down another 40mm from your current height. I lowered my seats with JCR kit, even though I had the ford modified version. The position of JCR at lowest works great for me, I’m 6’4’’.
