I know there is a big difference between the spring for a Z4 Sport & Z4 Si modles,
but does anyone know wether SPORT Springs fit ALL sport models (i.e. a 2.0lt & 2.5lt) or are they engine size specific ?? :?
Optional extras on the car, I believe, which I presume make the car a tad heavier requiring a slightly different spring. Might be worth ringing Suplex in Sheffield and asking the question.
If you look at the full correct list of springs, there are so many different variations.
Got mine from Suplex on Lillywhites recommendation (01909 770660) and for a 3.0i E85 M-Tec setup, the total cost including next day delivery was only £109.00
