The roof on the 2020 plus 6 is more or less exactly the same as the outgoing trad, drips and a lot of air around the kidney area from the doors. Just had the pillar rubbers upgraded but has made the roof rail much more tight. On our recent trip back from Malvern it rained we still had some drips but when I Put the car back in the garage I released the tension on the rear rail which I think I will carry on with from now on.One of the guys I spoke with said the earlier roof with the flaps over the door is better than the flush newer version. Over tension on the header rail might be an issue there is no chasis twist on the plus 6 for sure . Em
