    now i have 17's with 235 tyres on, i thought it would help my cars handleing.

    but no, it just plough straight on. any sharp direction change

    would a 30mm suspension kit help/solve this

    the suspension is standard atm, but my mondeo estate turns in better on rubbish tyres and even when pushed hard the back comes round first in the dry.


    any suspension kit reccomendations?
    and ive seen horror stories on fitting kit etc with all the control arms and droplink etc. would it be best getting a garage to fit the kit?

    many thanks :)

    What tyres are you actually using and at what pressures.

    The main issue with the B5 is the engine is hung in front of the front axle. This isn't a good weight distribution for handling as it will be more prone to understeer.

    Saying that though I find the turn in and handling over all to be far far better than on my brothers V6 Mondeo.

    You could try running the back tyres a couple of psi higher.

    there michelien tyres i think.
    pressure are set to, std psi as the wheels are off a 2000 a4 i found a 2000 avant with similar engine and wheel size and out the pressures to that

    Well if you set the psi higher at the rear it's less likely to understeer.

    Or get some stiff rear anti-roll bars fitted.

    did it plough streight on before?

    if not, the tyres you have now are likely to blame. Just because they are michelins doesnt mean they are good or grippy. If its designed to do 40k miles and minimise fuel economy its not going to grip worth a f00k.

    if it did, it could still be the tyres.

    Find out exactly what tyres are fitted to the car...

    I'd also look at getting the alignment checked on the front.

    i doubt lowering the car will actually stop the understeer as the ride height has very little to do with the mechanical grip available. My last car was an Astra and when i first had it i ran it on stock tractoresque suspension with 16" alloys and uniroyal rainsports. It felt horrible and cornered on the door handles, but it still gripped, once i lowered it and fitted koni adjustables it felt much more stable and was nicer to drive, but i didnt notice any great increase in the limits of adhesion.

    it had 195/60or65 r15's pirrellis on before and handled like a boat,
    the new tyres have increased feel, but it still understeers more than i would like,

    there tracking and alignment was checked by a audi specialist,

    I'm running 245s and I spend more time catching oversteer than suffering understeer. I do have a tendency to provoke drifts though :)

    I'm guessing yours isn't quattro?

    adam you still havent said what tyres are on the new rims...

    is the car a sport? i notice you say the original tyres were 15's which means its probably not a sport... i'm wondering if fitting sport antiroll bars and suspension all round might help things out a bit. The reduced bodyroll causes less weight transfer on cornering which should help with the understeer.

    New stiffer ARBs would be a great way to dial out some of that understeer.

    yer even a set of sport ARB's would likely make a difference!

    A mate of mine had driven a 1.9TDI before driving our 1.8T sport and he said the Sports quickrack, arbs and suspension made it feel like a completely different car to drive compared to the TDI

    is the sport suspension that different?

    if i got sport arb's or whiteline ones and a suspension kit that should help.

    how much would i be looking to pay for 2nd hand sports arb's and suspension?
    is the sport suspension any lower than my car?

    sports suspension is 20mm lower than stock.

    The ARB's and steering rack are the same as those used on the S4, the ARB's are thicker and the rack has less turns lock to lock

    whiteline/h&r will be uprated over the stock ones so will make the car roll less than a sport. I think if you find someone breaking a sport you shouldnt pay too much for the parts though, theres a car being broken just now on there iirc so you could try there...

    how much is reasonable for sport arb's on there own,

    ill start with them

    then how much is sport suspension worth on its own.
