tee hee - it's a 230TE so you can draw your own conclusions
What is strange is that the speedo is more accurate with this tyre wheel combo than the original 195/65/15 set up - I think Ian Walker will back me up on this as he got the same results - perhaps the W124 was originally designed for 16" rims?
Not sure of BHP on C36. It ranges somewhere between 270 and 290 depending on which review/which fuel used etc...So I'm using 270 bhp as a ball park to get an indication. 0-60 times are officially 6.4 ish seconds although I've read a couple of reviews at 6.7 and some quicker. Has anyone actually tried a 0-60 run in their C36 to get a definitive answer. I've not tried myself yet as I haven't had the car long and its got a couple of things that need sorting before I go too mad in it.
