Better cornering

Hey guys, if I don't want to lower the vehicle what is the least expensive and best mod to improve cornering on these M3s? Love to hear your experience. Too much sway with mine. Need it tighter. Thank u

Yeah, you really should try using the search function.

Here's my somewhat cheap short list:

1) New tires, (Tire Rack) my choice would be Hankook R-S3
http://www.tirerack.com/tires/tires....22V2&tab=Sizes

2) Turner Motorsport F&R SwayBars
http://www.turnermotorsport.com/p-26...r-upgrade.aspx


These upgrades can both be bought from forum sponsors, & will completely transform a stock suspension/handling BMW.



Good luck,
Rob43

Your experience is crucial. Thanks again...

Didn't know about the tires - thanks! But I did see these TurnerMotorSport sway bars and read through their description. I was leaning towards these. It is good to have you guys back me up. Want to spend the money only once if I can help it. Thank you...

Have all of your bushings inspected.

agreed if the M3 "feels sloppy around corners" inspect your suspension's bushings. replace with new M3 bushings or upgraded aftermarket bushings.

if you have "too much sway" gets some adjustable H&R/TMS sway bars (or Hotchkis bars). Rogue Engineering front bar another good option.

Michelin summer tires are great. Super sports are fantastic.

If it feels sloppy, you need to replace your bushings front and rear.

Are you tracking the car or just want to take city corners fast? How long have you been driving? Do you know to brake before the turn, and add throttle after it after downshifting...sort of thing?

Sorry...I have no idea what you know. I got Z-rated Kumhos cheap from tirerack that I like. They'll probably only last 30K miles though...and mine are huge old fat tires and I corner just fine. Make sure your tire pressure is right too, of course--from the door jamb...and you can dial in your under/over steering by making minor adjustments from the door jamb. I usually run on the highest front pressure and in the middle on the rear and my steering is basically neutral. If you stick with door jamb pressure exactly, you'll have some understeer.

i say after market sway bars

barbarian sways did it for me and if you have coil overs I would say get them corner balance that would help a lot to.....

and I would say check your cross brace in the engine compt. make sure that is nice and tight and no sway in that that will help you out to....

Check all your bushings.

Specifically the steering tie rods.
FCABs
RTABs (upgrade to poly)

New front tires...

Michelin pilot super sports are the best

If you have to save some money get the eagle F1 asym. I have them and they are really good.

Then get an alignment.

Then get a good set of sway bars. Or check your stock bushings and endlinks.

How old are your shocks? You can always get a set of bilsteins.

But definitly check all your bushings for slop. Thats usually the culprit
