How badly is this going to slow down my e90?

WhiteonWheat · 04-06-2011, 03:08 PM

I want to go from my stock OEM 17" (run flats) to: Miro 111 19"

I mean in all honesty, I don't have a clue as to how badly this will slow down my car....I don't know the wheel weight of the OEM's with run flats. I do know that these Miro 111's are like 24lbs or so a piece....

Am I going to have to go with light weight two-piece rotors to make up for some of the un-sprung weight difference?

Also anyone that has gone from 17" to 19" - how has it effected your ride quality. The car drives on "glass" now and I'm sure that's going to change if I go with these Miro 19"s.

Another newbie question - how much am I going to have to lower the sedan to even out the ride height going from 17" to 19".....

Flame suit on......

Go!...

LOL

Thanks Guys!

IDK but I went from to 18s on my E90 and the car actually runs better and feels lighter. The runflats seem to be the bane of BMW's existance.

Your stock 17" rims weigh 22-24 pounds as it is. Your runflats are at least 5 pounds heavier than whatever 19" non-runflat tires you put on. You're actually going to save a little weight.

Oh WOW - great. Do any of you go for the two-piece light weight rotors? I thought about doing that as well...just to help out...

Oh....and anyone know if these Miro 111's are going to be solid or give me troubles?? Cracking, etc?? Maybe they are too new for anyone to know....?

Thanks Guys!
