It took me a while to work it out but a quick call to the supplier confirmed it. These springs will take you down to 35mm at the front though mate. You need to have a look at the bold print at the bottom of the page.
Its getting annoying how everyone insists that people to go for Bilstein setup's. Its down to the individuals requirements, the ride height they are after and finally their budget. There is no doubt that Bilstein are an excellent setup but they are out of some peoples price range. Equally Kam Racing is an excellent place for car parts, however there are certain makes you cant buy from them which reduces your choice. If you want to follow the sheep or have a hefty bank account then Bilstein all the way mate
baaaaaaahhhhhhhh...
