S4 / RS4 (B5 Platform) Discussion Discussion forum for the B5 Audi S4 & RS4 produced from 1998-2002

Took a 135-degree corner last night at maximum speed (for that corner, not the S4's top end)...

...and the S4 definitely exhibits some understeer. At the limit cornering (and overall cornering grip -- maybe the tires?) is not as good as an M3. That quattro will pull you back onto track however and makes for a lot more fun at 80%.

Default How about ...

more weight in the trunk?

I always feel that my A4 handles much better with a full tank of gas. My guess is that the car is going more toward the 50/50 balance.

Now with my 12V A4, I can't afford any more weight but with all the power of S4, why not try adding some weight in the trunk (30-40 pounds) and see if the car handles better.

thinking about A6 2.7T with S4 wheels and springs...

Default Very funny, lets talk apples to Audis...(long)

The BMW sport suspension is much stiffer than the S4. Yes, it's true, even with the castrated 99-2000 series. And guess what?! They also have much wider, higher performance tires, on wider rims. The mission of the M3 (now really only for the lightweight series) is racing. That is not the mission of the S4. Put the same width rims with the same tires and the S4 will handle very similarly.

BUT, not identically. I personally love the dynamics of RWD on the track. It will almost always oversteer with enough power and sloppy driving. Now, in the real world, I prefer AWD. Yes, it does understeer! This is vastly safer on the street, yes, and even racing. You can solve this understeer one of two really easy ways, learn to drive USING the car's dynamics (this is not a slam, almost no one knows how to drive Q properly). And/or you can put lower aspect ratio (and/or wider [P0, P+1]) tires on the front. This has always been the secret for performance with our 50:50 differential.

You can't really put wider tires on the S4 the way you can with an M3

I too was surprised by that in the S4 I test drove...I think the tires are the culprit.

How would you get S4 wheels and springs on a A6 2.7T?

Yeah, I heard that different width tires will mess up the quattro

Default Why?

I see where different diameters would be a BIG problem, but the Torsen would be totally "unaware" of tire widths.
