Hello, Dragan,
congrats for your choose . I would suggest to check the downstop setting, the set screws should not be simmetric. Please take a look from front on ground level, slowly lift the bumper in center (put your battery on). The front tires must leave the ground in the same moment. Hope you will see the differency in the downstop setting. Have luck!

found the cause of my problem...

entire lower chassis plate was bent, believe it or not. This probably happened while I was doing my first strip down of the car... And when putting everything back together - I did not cross tighten the screws, so the chassis flexed a bit

I've loosened all the screws now, and I'm letting the chassis "breathe" a bit. Hopefully, it's gonna revert to normal shape in full... Already looks better as it is, not tightened/under stress.

edit: another question... How to acquire that nice chrome rear bumper for BMW 2002 shell, just as in official HPI photos?

I have a chrome kit upgrade, but there's no bumper in it... So I'm left with just a standard decal that doesn't even fit smoothly

sorry for misunderstanding. The screws are simmetric, of course, but not necessarily in simmetric position. If you lift the front or the rear end of the car, the two tires must leave the ground in the same time. That was what I mentioned "simmetric setting". Befor this test you may need to set the height of the chassis equally on both side to have a "horizontal" position. have fun!

Does anyone know if the cup racer differentials would fit into rs4 pro 4? Or is anyone willing to measure the distance between the bearing on the differentials? I would really like a gear diff. Thanks

I was fortunate enough to pick up a new cup racer kit, Exotek CRX chassis kit with rear shock tower, and what must be the last HPI brake rotor kits at any hobby shop. I'm figuring out the assembly sequence for the HPI threaded aluminum shock bodies, with no instructions included. I was able to source one of the Porsche body sets and am in search of a second. I contacted Mike at Exotek regarding the metal drive cup that was discontinued to no avail. I did find a guy in the UK that will machine one for 36 or about $56 US. Perhaps if there were enough people interested here, we could have him produce a quantity that would save us money and make it worth his time. Send me a PM if you are in need of this part and we'll look into ordering some.
