With winter tires and 16 inch steel wheels car is much more agile and responsive. Don't have dragy to mesure diference in acceleration, but I can feel it, car is faster from standstill. Been readind that Porche make some testing about wheel mass. They said that 1kg in rotation is equal as 6kg of load in the car. So..... mass of the wheel is very important for preformance of the car. Lighter the wheel you get better braking(less mass to stop from rotation). Big wheels look great..... but smaller wheels preforme better. Bmw power. 😎💪

Hi Riccardo I have never experienced the problem youre describing. I dont shift slowly in this car either. Filling it with aft6 greatly improves the shifting feel and speed versus old oil. The problem youre describing doesnt sound like a gearbox problem though. But maybe more of a clutch problem really. Or a slave cylinder issue perhaps. Issues with the clutch can affect the gearbox as well resulting in sometimes, clunky shifts. But maybe im misunderstanding you. Do you mean that the 1st to 2nd shift sometimes is tricky so when you release the clutch the rpm is too high and the car will jerk foreward as the clutch engages? If so. I have had great luck with liqui molys gear protect and atf6 combined in the getrags 420g

If you do this video again, roll runs will be far more accurate in showing the speed difference because it eliminates the tire (compound/tread and age) differences that effect traction at launch. Something like a 20-100kph or 20-150kph (if you have the road for it) would make for a much more conclusive comparison.

guys i have standart suspesion 2005 e46 330d RWD touring, would 19 inch bmw style 167 rims,fit without rolling fenders and what do you think about this tire setup, front :235/40/R19 rear : 255/35/R19

Mate, nice channel btw. I own the very same car. Really interesting because I installed M3 Style 67 (19 inches). According to RealOEM these rims weighs only 11,8kg & 12,4kg. The weight for Style 68 are 10,15 kg & 10,55kg (Front&rear). My guessing is that weight difference in your measurements are due to incorrect tire size, adding rubber and pressed air where there is no need. Regarding diameter, in Spain is only legal to change rims if you adapt the size of the rubber, so I am running 225/35/19 front & 265/30/19 rear. In this rubber the total diameter is even smaller, gaining less flank & precision through corners. Acceleration I couldnt tell, but for sure I gained traction at corner exits. To be honest, the combination of less height & wider rubber compensates any loss in pure acceleration. Personal opinion, of course.

All mods should get an inspection similar to German TUV and some reports. The process is something called “homologation”. You need to get an official report from the fabricator that the part meets BMW Technical regulations, a second report from a mechanical engineer and finally a workshop stamp that the part has been installed correctly. Finally, Spanish TUV inspection. Long and money consuming. There are shortcuts if the fabricator has made it before (Recaro seats I.e.), but generally you need lots of money for it.

All the same wheel size, no tires on any of them, and they have to be the same exact model. Or at the very least similar models. I really want to see if there's a weight difference.

@@OEMplusRESTO offer up. That's my goto for everything.

Hey buddy, interesting video. A couple of important points: - The 17s are definitely going to give you faster acceleration than both the 18s and 19s. - It's never about the rims, it's always about the tire height, or the total diameter of your wheel, because now you're adding torque, it's like you're slightly altering your differential to a more acceleration-biased one. - When you run your acceleration tests, if you have old tires, your DSC will compromise a lot of your time, that's when the car is periodically cutting off power to limit the spin, that's why you were experiencing 40 and above better acceleration. - We will never know better than what the manufacturer what tire size is best for the car, remember, a car handles better on turns with its original designated height because there's a separate calculation dedicated to how much the car rolls sideways over its tipping point, thus putting down all the downforce for better handling. I have a 2003 e46 320ci that I've swapped for a tuned M54B30 from a 2006 X3 with headers and straight pipes and some other bits and tunes, I now make sub 5 seconds on a good day (Manual transmition) and that's also because I've installed a shorter differential. The only downside of reducing your wheel diameter is top speed and that's all but the acceleration will definitely be better.

I should have tested it 50-110kmh in the same gear which is what im doing now for various other parts testing. While the gearing change certainly matters, wheel weight does too. I think you will find my diff test video interesting, a 2.93 diff is faster to 100kmh than a 3.38 due to one less gearchange. But the 3.38 accelerates much harder in gear. I will repeat this video again when im able to afford (and find) the right wheels:)

Hi! You’ve ashed how could you improve the video so here’s my input: - Could have put wheels on a weight and show the results (cheap house weight with 0.1kg precision) - Record few launches and show best of each on all setups. - To be anywhere deterministic you’d have to have same sizes and tires for 0-100. If you can’t afford to make it happen it’s better to show rolling start results where tire grip won’t affect the result. - More to the point, less talking around. - Make your vid’s more informational, I.ex. about benefits of lower unsprung mass in car, how it benefits handling and elongate life of suspension components, benefits of higher side wall of tire, how it helps absorbing so less stress on suspension also more comfortable for the driver and passengers. Slimmer and lighter wheel equal lower fuel consumption. How a bigger radius of mass makes it so cars lose a lot of power just to move something that’s heavy and further from center. Also negatives of slimmer tires (I. ex. less grip on dry, higher braking distances), higher side wall ( I. Ex. worser feedback). Good result overall, liked - just not enough to subscribe yet, keep going ;)
