RS4s and slick tyres

Hi all

Have any of you B7 owners ever run your RS4 around the track on slicks?

Something I am contemplating as and when (if!) the B8 turns up !

I think Sonny is the only active member who has run track rubber. As a passenger the B7 felt bang on.

Only ran R888 in 255/30/18 format. Car was spot on. I wondered what full on slicks would feel like, but most track day organisers require a cage I be used with slicks. Expect the chassis to twist as well with slicks so you might get a few squeaks afterwards once used.

I have the Yokohama equivalents on the exige as my 'dry' tyre so know they are good but I was thinking full slicks for the RS as I would have room in the boot for some normal tyres too

RMA don't seem to require a cage

Ps I did wonder if the extra grip would put too much stress on the car. Maybe the 888s are the way forward on a spare set of wheels (maybe 18/19s) which could double up as winter wheels with proper winter tyres in the winter

Whilst you guys seem switched on and without starting any unnecessary new threads - have you seen if there is anybody on here that ordered the carbon ceramic brakes on their RS5/6 ?

Only if you have the bench stripped out as in some cars it helps make the car more rigid. Mine has been fine with the R888s.

Ok that's good then, I think its mandatory for MSV days.

I would strongly advise not to run slicks on standard suspension.

The jump between road and track tyre is a lot however it's trivial compared to the jump from track tyre to full slick.
You at least want to make sure all track and tie rods are up to it as they will take a beating.

Fwiw, I've run many cars on slicks and track rubber and tbh for a track day I wouldnt want to use slicks. They don't like sliding and are very unforgiving near the limit. Slightest bit of moisture and whoosh - no grip.
For racing or competition fine but most people used to normal tyres can often be initially slower on full slicks.
