[urq] re-quattro-ing a quattro - ALSO

[Keith Lloyd]

Because from now on I'm looking after the old girl better (my quattro) I'm 
not going to be using her in the bad weather this year so I've put my 6" 
ronals and snow tyres on my '98 A4 Avant. It was a tight fit between the 
stick-on wheel weights and the calipers but after cleaning off corrosion on 
the calipers with an angle grinder/wire brush there was no more 
interference. Are they compatible with the A4? They are the same offset as 
the stock wheels. The wheel and tyre size was an option at the time and the 
are specified size for winter tyres for the A4, so yes they are. And guess 
what? They improve the feel and ride of the A4 hugely. Great stuff. Might 
leave them on all year.

It's an interesting observation. I have heard that Porsches at least
are extremely sensitive to the correct tire size being used for proper
alignment. In addition to the probability that a suspension that's
been lowered more than 1/2"-1" just won't work like it was designed
to, wider wheels with different offsets than the original design must
surely also have the potential to reduce optimum response. It makes me
wonder if Audi thought much about this when they switched to the wider
and further-outboard offset 15x8s. I've always loved the aesthetics of
wide tires and there is no questioning the firm grip on flat, dry
pavement, but when I rolled with 6" wheels and 195-width snow tires
for a few weeks with my car, I was amazed at how much more normal
everything felt and how much less I had to fight with it over bumps
and rutted roads. My embracing of the rugged "well it's a sports car
and needs to be wrestled with" atittude has given way with age to "it
would be nice if this drove like a normal car"...

It would be super interesting to have a back-to back test from the
same driver of lateral grip, braking, and slalom handling of a car
with stock ride height and 205-width tires on stock 6" rims vs.
lowered with wider-stance 225's and see if the perceived benefits of a
lower car with wider tires and stance actually equate to real world
performance increases. I would not be entirely surprised if the former
actually "danced" more nimbly.
