Re: Tramlining with 17's

[Nicolas.Roman@xxxxxxxxxx]

Guys,

Pardon my ignorance but what does Tramlining mean? I own a 94 e36 and i
have had 17" momo sports with good year tires for over a year and i haven't
noticed anything wrong with it....

You guys need to upgrade your upper strut mounts to E36 M3 parts.  I
beleive
they change both camber and castor up front.  This upgrade should greatly
reduce tramlining if you run 17" wheels.  I ran 17" wheels on my stock E36
325i for about week before I decided to upgrade to full M3 suspension
(springs, shocks, sway bars, AND upper strut mounts).  I couldn't take the
tramlining with 17's on stock suspension.  The extra grip just wasn't worth
it.

looking for E36 wheels/suspension?)
