    Somebody makes a K1 drum that holds more clutches, it strengthens the 1-2 shift. I have to look it up who made that but it was mainly to strengthen for high horsepower figures.

    I would only assume that low hp #'s like 400 range (5.4L) and a strong built trans would just last much longer!

    Yes id expect if its a good part it should last a very long life, but its not the horsepower figures thatll kill it as much as it is the torque.

    Since the throttle plate shuts briefly during that shift id expect the life to be really quite long, in my 95 C180 im up over 354,000 without a hitch on it's 4 speed, its had 200,000 of shifting first to second under near full load every time.

    Apologize, the high tq. Figures would do more damage then HP.

    KC,
    You heard right ... the one I got was up first and someone bid furiously against me to $4750aud, the second one went for $3750aud, both with lite a-piller damage, they are the first rhd clk55's I've seen damaged in 2 years. Have seen a 99 E55 at one stage not sure what it went for,Keep a look out on pickles,I'll let you know if I find anything else!.

    Cutout, the pressed in area's required cutting to allow the recess to fit flush, the clk boot doesn't appear to have this. the metal is so soft you could almost beat it with a soft mallet to the desired effect.

    Cant see those attachments, can you upload them to photobucket instead so they automatically load on the page?

    Can you get the correct 3.07:1 gears to fit it?

    Mate if you see anything that cheap, either E or CLK or whatever else i can take a direct swap 55 engine from, let me know, ill grab it!!

    Sometimes the attachments bug not sure why, I'm attaching as I assume they are loaded locally on club202, hopefully this outlives photo hosting sites and there's less dead pics in future!

    I have heard there is a large case diff with 3.06...I cant recall which model it is from though.

    Itd be ideal if there was a straight swap in LSD for the standard rear end in the C43, its strange the C36 had one and the others dont.

    Does the CLK or E 55s have an LSD?

    I think itll be a bit of a handful getting off the line with the 55 engine and stock diff with no LSD.

    C36,C43,CLK55,E55 none ever had lsd afaik.

    The ESP brakes the spinning wheel for lsd effect, of course not as good as the real thing though still much better than totally open!.

    Edit - do some mechanical lsd's cause understeer?

    The C36 does indeed have an LSD from all ive been told, very long time since i drove one, they were asking $68,990 for it at that time, so i bought another Corvette.

    It would have to be a very tight LSD to cause understeer, id be more concerned about power-on oversteer.

    My 95 C180 will spin both wheels evenly too... In the wet!!

    When my c230 was made someone opted for the LSD, my data card shows it and the 2 marks left on the pavement prove it

    the 2.3 leaves marks? =P

    What year is yours?, some 4 cylinders run the smaller 124 diff iirc. same as some 190's etc, maybe your option was a similar clutchpack style to the 16v 190 back then?.

    Both the 97' US spec C36's I've had, no LSD. I believe the ASR was in place to correct traction.

    And I have yet to come across anything in the US with LSD.

    Only my 211 E55 had it installed after later on as a upgrade.

    I always had my eye out for a BMW E30 325is 3.73 LSD because they looked very close in size as well as someone telling me the axle bolt patterns were the same, all I'd have to do is fabricate the diff mount points and convert my driveline to U-joint instead of rubber disc. Just a rumour.

    As far as I know C36 started out with ASR, at some stage this incorporated braking of the spinning wheel to mimic an LSD, later when ESP came along( C43 onwards) it incorporated all that plus yaw control.

    EPC doesnt show any lsd diffs for C36, only ASR is mentioned with the diff part numbers which iirc is a sensor slot on the diff housing?.

    The one i drove never had traction control, i thought they all wouldve by then but this one didnt, no button for it either. It had abit of trouble spinning the wheels for long anyway, it just seemed to want to take off instead. Was quite fast once it was moving.

    3.73 would be good for the 5-speed manual,

    I ran a 3.69 before along with a 6-speed manual and boy that was fun! But in the hands of the inexperienced, well, that's why that car is now parting out!

    Yes i was going to say would be fine for a manual, single or double over drive, but the auto would leave you revvin the s*** out of it on the highway!!

    I helped swap out my mate's 91 ZR1 to 4.10:1 from the stock 3.54:1, i reckon it was the best money ever spent on the perfomance of that particular car.

    later MB 6-speed manuals in the higher torque application run 2.47 rear,2.82 should be perfect for the C43 then?

    With a 55 engine maybe, but i wouldnt want it any taller with the 43 engine in there!!

    Id have to guess 1st in those 6 speeds would be a lower gear than the autos by quite abit, and possibly even 2nd as well, if they are using such a tall diff id say 6th is a 1:1 ratio, or 6th would be damn near useless.

    I wonder if its an over drive 6 speed in those at all then?

    Id be interested to know some gear ratios for their boxes.

    Probably way too much effort to get a bloody 7 speed in there!! If that could be done, youd then have full tiptronic control.
