Ohleins are 4 times the price!
The BC's will be a great addition to your car Waffle.
I have them on mine (I'll get ohleins when IV saved up) been on for loads of track days and plenty of nurburgring trips.
Settings wise, just experiment with them if it's just road use. Probably start on the middle settings 15 front 15 rear.
Just remember not to run them on 0/1 settings (softest),it should say that on the instructions it's not good for them.
My ultimate advise would be fit them, then get it booked in somewhere for a really good geometry set up "fast road" will suit. Try and take it to somewhere that preps race cars etc etc it will transform the car :twisted:
