Hello fellow M-42's.  Have a 1992 original owne,r Bilstein Shocks, otherwise unmodified, calypso red, 172,000 mile lots of fun 318is.  Like the lightness of the vehicle, nimble responsiveness .  Look forward to reading about and sharing info on this Forum.

First question:  Have you chipped your M-42?  Which chip?  Is it worthwhile to put chip in?  What are the downsides to it?

I know this is probably an old question (it is for me) but am really interested in your opinions.

thanx

Jim Conforti chips are the way to go from what I hear. 

gotta see pic's of your car too, sounds pretty good - what type of shocks, sport or heavy duty?

Hey there, I am new to the forum, just wanted to pop in and say Hi, I am just looking around checking out the chat. Abe

Welcome aboard.  Here in the states the S usually means coupe or two door.  On some earlier models the S could mean sport package.  So a 318 convertible would be an S, since all convertibles are coupes.  Generally over here the verts are referred to as C, so yours is 318ic.  The convertibles generally have a stiffer rear spring to handle the extra weight, and the layout of the rear suspension might be slightly different.  The front part of cars are not different.  Get a Bently manual or Haynes repair manual and it will help you very much.  Also use www.realoem.co m to help answer systems questions about your car.
