mbzslk230k, Your website says that you would like the BRABUS K1 Tuningkit for your SLK. Do you know anything about this? The W202 C-Class is not listed on the Brabus site any more only the W203, but I expect the 2.3 Kompressor Pulley upgrades are very similar. For the SLK and CLK 230K's it lists: BRABUS K1 Tuningkit, 210 hp / 154 kW BRABUS K1 S Tuningkit, 220 hp / 162 kW, Export only! Have you ever had a quote? The estimate I got from Carlsson scared me into giving up on the idea. I wondered how much more of a laugh the cost from Brabus is?
