I know you are faithful to your rims, fixed your scratches yet?

No, I want to so my car wash lady will not think I don't care about my car and not be more careful than she already is
But I have to install my 9-camera parking cam system.. its about 20-30%complete (but I started half a yr ago)
Wah, I dun understand how the 535gt can go 6.3s when the 535i is listed at 6.1.. and its 300kgs heavier. How do they make that dissapear and yet similar weighing rims can have a such a large effect.. we need steven hawking to investigate this after he is finishing talking about god whether there is heaven
My switch to 19' was similar bumpy, maybe only land after speed bump at low speed feels heavier, i have skinnier tires 225/255 maybe feel less 'hugging' the road, and more like taxi

Yea but im striving to be a wheel slut like mlai[/QUOTE]

Wheel slut no so bad.. means actually you're a faithful guy in other areas
Actually playing with rims and tires not so bad, all you can get is curb rash.. and the mechanic boy won't ask where you got it

Jxnco, please give us a review after you have done some mileage on your new wheels. You've been with your stock long enough to give us a review more justice. Hope I am not bias, I kept selling bros here to swap their springs and wheels.

I drove for 2 months with my stock rims so I have a pretty good feel of how stock should feel like. And after driving for about 200 KM with my new set up, this is what I can say:

1. In terms of acceleration, no change at all. I don't think it's any faster or slower. Feels exactly the same as before.

2. In terms of braking, I would say braking improved by about 10-15%. This is probably because of the reduced unsprung weight ( I shed close to 45 lbs). I don't have that feeling of skidding if I hit the brakes hard. It's a heavy car and factor in how much unsprung weight it has, you have to be worried about how much momentum it has when you do a sudden stop.

3. In terms of noise, same as stock. I don't think it's any noiser. This is probably due to the tires. Michelin's are really soft and quiet. RC3 thinks the Advan's are noisier.

4. In terms of comfort, surprisingly, almost the same as stock. It's not bumpier or harsher. Well maybe just 5% harsher? My wife never noticed any change to the ride comfort. She thinks it's the same as before.

5. In terms of drop if it's too much, not at all. This was my biggest worry before. Turned out it's completely fine. The F10's tire size is big. Even with the 1.4" drop, it's still higher than most cars.

6. In terms of handling, this is where it gets interesting. I can feel better control of the car. It finally drives like a BMW. I can do sharper turns with ease at the speed I want. The car actually goes where you want it to go without any hesitation. Driving the car is a lot more fun now! Best part is, my wife noticed the body roll got reduced.

Overall, a very worthwhile upgrade. Aside from making the car look sexier, I got better performance. I highly recommend it to everyone who wishes to improve handling while maintaining passenger comfort. Of course, you need to pick the wheels, tires, and springs wisely. So far, my combo worked beautifully.

Just my 2 cents.

I am contemplating springs myself as well. Don't know if the H&R will be right for the 550 as it is considerably heavier? Even ACS has a separate sku for 550i vs everything else......

Great review Jxnco.

Seems like the PS2 out performs the Advan Sport (as expected). Next time I'll spend a few k more for a set of better tires.

From this forum, it seems like most people who got H&R for 550 and even 535 complained the front is too low. R&D might be a better choice for the 550.

Check this thread.

Totally with you on that. Tires are the only thing that connects your car to the road and is one of the more important if not the most important "safety" component of your car.

That's my concern.... Even the RD ones are a bit too low on the front for my taste

Good news, that handling can be improved considerably with lowering.. though im satisfied now, when the time comes i will def lower

eibach has diff springs for each, dun know H&R. if you want to be adventurous, you can 'pad' the spring to get whatever height you want, or even more adventurous, see if the springs for heavier models (750,X5 etc) are similar size

Congratulation, you can enjoy yr mod.
But for me, I am surely not change back to the 19"or 20" wheel again. I am really sensitive that the increasing of bumpy & noise
and the torque reducing.
The performance is more important than the good look for me.
Now I choose less bumply & noisy and better torque rather than good grip and outlook.
Later, may be change the tire little bit wider (may be 245) for the front only. Haha !!! The rear no need be changed since 528i power is not enough 用盡條呔.
hehe

Bro, not sure what you are talking about here. Me and Jxnco both are driving 528 and have 20" flow formed rims. We have tried, tested and proven the set up is NOT that much bumpier and has NOT degraded the car's performance. In fact the cornering of the stock absolutely will have no match to our set up. Are you trying to tell us your guessing is more accurate than our personal experience and review?

[hksl]

I would think 19'/20' non-RFT would have similar ride to OE RFT 17's especially those horrible Goodyears. Since you guys got really light wheels, I would imagine that would ride and handle beautifully.

I also have a 528 and I think it has plenty of power, course I'm cheap I'm going to get 18' OE take offs with 245/275 staggered set up.

I just express my feeling about the experience of the 20" wheel swap
The different drivers have different feeling.
I am not challenge something or someone.
And there is no a real test about the data of the performance with different wheel .
So it cannot be argued!

The weight of 327 is 11.88kg= 26.2lbs and 356 weight in at 15.6kg=34.4lbs

Exactly! I think BMMW's 20" experience was ruined by the 356s

275 rear will consumed more fuel and reduce the torque .

Yes. So get lighter tyres

How about get lighter 17" rim and non-RFT.

Non-RFT will help. But not quite sure how much of a difference you are going to see with lighter rims

How about yr F14 rim feeling now after a period driving?
