possible weight for a C4
#61
i have an update here:
Got my car back from the workshop (were the unibal conversion was installed). Some additional mods are done in between (GT3 starter-motor, LIFEPO4 battery, and other - smaller stuff). With 1/4 fuel, the car weights 1230kg at the corner balancing scales.... still with steel bonnet/hood.
Quite impressive numbers for me. Next step is carbon rear bonnet (already in my garage) and - perhaps - carbon hood...

all parts, except the part under the gearbox/engine are part of marcus portfolio (http://www.kunststofftechnik-buehler.de/). Perhaps you`ve to ask for some of the parts....

and the next weight-loss is already triggered.
Yesterday, i was at buehler-kunststofftechnik and Marcus bespoked one of his gorgeous front hoods for my car. That`s the first -10kg.
Then, i got an carbon engine deck-lid from a friend that was a little bit cutted for using at a race-car applicaton. Marcus will repair this and that´s the next -4kg...
After the paintshop and fittment, i should see something like 1215kg on the scales :-)
Marcus discouraged me, to fit carbon doors. With that, i have just a "solution" for the sunroof "problem" open... I`ve to see, how to handle the sunroof during the next month/years...
Next step could be an electrical steering pump....
regards

i know, i anybody would offer a lightweight wheel with the weight of the fuchs wheel with a "better" design (i do not like this wheel on 964s, two of my buddies have this wheel on their cars...), i would save round about 10 - 14kg...
MM Cup1 are quite heavy!
Regarding the steering are some thoughts ongoing... one option would be a manual conversion, another option an electrical pump conversion...

according to a few people here electric pump is the way to go, not saving a lot but move weight forward and a cleaner engine bay,
have my Mercs one a side ready
the wheels are great mod Allegeritas 8kg fronts and 8.5 rears, saved me around 16 kg, not bad for suspended weight too

Why not do a sun roof delete with a DP motorsport carbon roof panel while you have your other carbon parts painted.
MM Cup 1 wheels are very heavy, I used Fikse forged split rim wheels, saved a ton of weight, so much that my next mod will be power steering delete.
This should get you down to 1190ish kgs
PS I drove past Frankfurt yesterday morning, didn't see your car so must have been washing it

Sunroof: my plan is to convert it to non - sunroof with steel... perhaps, i`ll use a sunroof pattern/inlay as intermediate solution.... I am not such motivated for a paintjob for the full car...
Next will be powersteering/delete or electrical conversion... after that, perhaps CF-doors, together with a full cage...

hi Guys,
another update here.
I am in the process of performing my winter-jobs. I did a de-servo job with my steering rack. So i can remove the power-steering pump. I have used elefant bump-steer tie rods... well, over all that`s another ~8kg decreasement of weight.
I also remove the front bumper beam. I will create a "cup tow hook" remove the ~5kg of the front bumper beam.
Next job is (was) a couple of carbon bits from buehler-carbon front-/rear. Another minus ~14kg.
As a last improvement for this winter, i bought a set of carrera 18` 5 spoke wheels. Compared to my MM Cup1 replicas, that an advantage of round about 10kg...
All together, i should decrease the weight of my car with another ~35kg.
With low fluel, i should have reached the 110x kg area with this.. Not bad for an C4 i guess...

Hi Thilo,
Great job ! would you put it on a scale soon ?
Me recently delete the sun roof, rs carpets, some sound proof removed, center console delete, radio & speakers, and all the knee pad glove box trimming and fitted DP rear windows €€
I will redo the geometry soon and accurately weigh it, I hope to see around 1270 KG from my C4...
I still have to do the electric pump and fibre glass engine cooling panels and delete the exhaust heat panels around the engine (should be done soon with the valve clearance ) and I guess that's another 8 kg from the rear .
