cool mod, I'll wait for the dragstrip testes if you share the difference between the stok 3.07 and 3.46 gears (you were running 3.07 before I guess, or 3.27? )

I'm thinking of putting 3.46 on my slk too, but I'm afraid of start issues on dragstrip, we don't have proper dragstrip with glue, so it's hard to push the car from the start. I only get 0-60 is 2.2 or 2.4 as I remember.

bob the slk-s have 245/40 stock size, not 245/45.
