  • The Rally E30 M3's

    How much of say a Prodrive rally M3, is different to the BTCC M3 that Prodrive would have building at the same time? While the DTM cars are well documented here, I know little of the rally cars.

    So does anyone know how the engines, the shell, the suspension or anything else would differ ?

        The engines are in a different state of tune certainly.
        The Rally engine is tuned for midrange punch and for midrange punch no matter what effective gearing they happen to use.
        The DTM car are tuned and geared to achieve max redline horse power for the longest staight of the particular circuit they are using that weekend....they made i think, 80hp minimum more than the least powerful DTM spec.
        I believe the bodies in white were not as extensively Um....*enhanced* on the rally cars as Boreham were not pulling the same shenaXXXXns as Cologne:p . So they were heavier and more like todays Group N.

          A mate has a works rally car in fact the twin of the Fina car pictured above. ( PRODRIVE )
          Engine wise as said above built for Midrange punch ( 300 bhp ) ( 9000rpm )
          Shell was much the same. Light weight glass, fuel cell in wheel well,
          Same six speed box running a lower final drive. ( 5.1 )
          Suspension was Bilistens longer travel.
          330mm discs up front with AP 4 pots 16in rims front 17in on the back.
          Weight 1200kg dry.
          I don't know much about the touring cars though, I would love to post photos of the car at some stage.
          Show me interest and I will take detailed pictures and post them.

            Thanks for the reply Declan . Some cool pics of the Ex Duez car in action there. I'm sure there's a lot of interest in more pics and details, so please do take some .

              Autohabit ( Alan ) was kind enough to find some magazines articles of the rally M3's for his archive and mail me the scans. Thanks Alan.



              Enjoy

                  This is all GREAT!!!

                  Next question for those that are well schooled (or can ask their mates) on the rally cars.
                  What spring rates and lengths are used for the various surfaces, i.e. tarmac, gravel-smooth, rough gravel? What damper rates and damper travel for the same conditions?

                  Details, man! This is like giving tuna to a shark. I want more information.

                        Prodrive were into using Speedline wheels back in the M3 days, so that would be my guess, no idea what the model name is though.

                          Spring rates I have no idea whats being used on my car, ( Very bumpy tarmac in Ireland )
                          I will find out over the weekend,
                          Getting car ready for the Circuit of Ireland International Rally next weekend.
                          Wheels are indeed Speedlines, I think they are called Corse, no longer made though.

                            How long have you had the car Declan? That really is a piece of BMW history you have. I'm surprised it's not in the BMW museum though pleased it's still doing the stuff on the stages.
