Understeer

[derin100]

Only my third drive of my Z4 3.0Si and only the second since fitting the new Goodyear AS2s all round.

One thing I have noticed is that the Z4 does seem to have quite a noticeable tendency towards understeer?

Seems like there are hundreds of posts on this topic which it would be impossible to trawl through but wondered if someone could offer a quick summary and easy/free solutions to reduce this a little?

Thanks in advance.

E46 M3 front ARB, polly bushes and a strut brace should help.

just out of interest, what size/thickness is the M3 front arb? and is it any better than H&R, eibach etc....

Coupe is 26mm and soft top is 27mm vs 24mm as standard I believe. No idea of aftermarket sizes, sorry.

Mine is being fitted in a couple of weeks, so personally unsure of impact yet, but everything I've red suggest it helps a chunk.

Pretty sure the si has 25mm front and 19mm rear

Yep, could be - mine is a pre facelift and I was talking front only obviously Again, no idea of the actual impact personally yet, but others say it helps, and for about £40 off eBay and a quick but of fitting, it's a modding no brained
