    Dear Sir or Madam,

    this year we celebrate our 40th anniversary of our company. We are a well knowen BMW performance tuner with our own racing team. We have a great racing history regarding the DTM, LeMans, at various 24 hour and long distance races and currently at the VLN on the Nordschleife. With MK-Motorsport you can experience Motorsport.

    We wonder why in rFactor2 there is no BMW E30 M3 available.

    Our MK-Motorsport BMW MK-E30 M3 was successfully piloted by Kurt Thim (father of Nicki Thiim!) in May 1988 on the Nürburgring to the overall victory and we would like to be able to immortalize our vehicle in rFactor2 for our anniversary. Compared to the factory BMW our vehicle body has its own form and look, because we designed and manufactured our own body parts (for example front and rear spoilers). Our customers can still order the MK-Motorsport DTM spoilers and body part kits for their E30 M3 today.

    How can we make a contribution to the community so that everyone benefits from an available BMW MK-E30 model?

    We would also like to help and support creating a MOD that covers the 1988 DTM season with all the Opels, Fords and Mercedes and also all the tracks, of course with our MK-Motorsport MK-E30 M3 as a 40th anniversary poster child.

    What is the oppinion of this community? Are there enough touring car entusiasts regarding a 1988 season mod?


    Best Regards

    Yes please. Not sure of your modding expertise, but I suspect there are a few who could help if you need it

    Mangoletsi's pic of the car above was recently updated by me including the physics and skin:
    your car has the following spec using the available data.
    It would be good to know your figures for the same.I do not think it has your company spoilers though.

    Mass=1040 kg // do you have mass without driver ?
    CG rear range=(0.490, 0.000, 0) // fraction of weight on rear tires 49% rear
    BodyDragBase=(0.339) // Base value An arbitrary coefficient which combines the effects of shape and the frontal area of the car as input to the body drag calculation
    BMW 2.6 I6 engine = 356 hp @ 8750 300 nm @ 8250

    these figures i have but probably in a format not used by you.
    gear ratios ?
    ride height ?
    BrakeOptimumTemp=?
    BrakeTorque=? or sizes
    spring and damper settings ?

    did your spoilers inprove drag and downforce?

    Hello Philrob,

    wow, such special questions right from the beginning. Counterquestion: for which track and which time of the year? :-D

    No, we had to fullfill a specific reglementation for DTM 1988 and we owned a preseason MK-E30 M3 that we have used for several long distance races like 24h Nürburgring or Spa. So we tuned our 1987 car to match the DTM 1988 rules.

    Rules for all BMW M3 Group A in 1988:

    Mass = 1040 kg // Our mass without driver was 960 kg

    Rear-wheel gearing (not sure if we use the same physical base): from 3,15 :1 to 5,28:1
    Gear Ratio (1.2.3.4.5-R):
    2,337:1
    1,681:1
    1,358:1
    1,150:1
    1,000:1
    2,660:1

    Steering ratio (rack) 17:1

    Wheel/Rims size 9x17

    BodyDragBase=(0.339) // I have no idea :-D

    BMW 2.3I 4 cylinders engine = 310 hp @ 7800 270 nm @ 7000
    (Ford: 320 hp Merc: 306 hp, Opel ~270hp)

    Cylinder capacity: 2332 ccm

    Drilling and stroke: 93,4 x 84,0

    Compaction fuel air ratio: 10,5:1

    Mixing preparation: BOSCH Motronic

    Sizes:
    Length height depth: 4355 1680 1330 mm
    Wheel base: 2656,5 mm
    Track gauge front: 1412 mm
    Track gauge back: 1424 mm
    fuel capacity: 110l

    ride height ? // not sure what you mean

    BrakeOptimumTemp=? // Can't answer today

    BrakeTorque=? or sizes // We had 4 piston breaks with 32x332mm brake disks at the front and 32x280mm at the back and special tweaks we will not talk about :-D
    spring and damper settings // Can't answer today

    did your spoilers inprove drag and downforce? Yes of course! But it will be hard for us to make them a number in the rF2 simulator.



    Best Regards,

    Werner

    I guess with ride height he means ,,Bodenfreiheit“. I'm German and English isn't my native language, so correct me if I'm wrong ;)

    If you have force @ speed numbers, we can easily calculate the rF2 numbers.

    ground clearance = Bodenfreiheit so i guess i was asking this
    Looks like i got some things right, but my engine is too powerful and (2.6 that is only in text though, no bearing on performance)
    This spec car in game ran through the DTM for 1988, with no particular single track or date GRAB_050.JPG but all tracks in the series.
    Was your 87 car the #38 Robert Walterscheid-Mueller ?
    This is how it looks at the moment in RF2.

    Bodenfreiheit = Can't answer today... :-D

    In 1987 we didn't had BORBET but TUFFI (tuffi.de) and Kenwood as Sponsors. But yes Robert did some races for us at DTM.

    The thing is that we will not be able to match all variables of all equations in reality. For example we started the first races with just ~295 hp and over the season we "learned" the car and maxed ~316 hp at our last race at Salzburgring. The Ford Cossworth had >500 hp for example. They had extra weights of +350kg in 87 to get equal with other cars. But because of the extra weight they always ruined their tyres which was dangerous to all cars on the track.

    Thats why in 88 the Ford got specific air restrictors to take their breath. The first two races they still blewed everyone from the circuits and so their air restrictors where extended. The result was the Ford was not competitive at all for another 3 races.

    Or if it was raining, the little front driven Opels took over the pace. There was no chance in the rain against the Opels.

    Not sure if rF2 can handle all this :-D

    Cheers

    Werner

    I'd love to see a car mod made with your input, but the rF2 transmission model is too rudimentary to do it justice. You should see if you can get someone with the skills to program a better one. Better yet, you could use AMS as a platform instead: http://www.game-automobilista.com/
