Will fitting the RS5 20" Rotor really affects handling/ride?

[Starry]

Spacers are illegal here unfortunately....

and I heard 3mm spacer (even hub centric ones) will likely to cause vibration as there is not much hub contact left. The beveled edge of the wheel face contact is not helping either.

Starry can you tell me more about your S3 setup? Cheers.

The aftermarket wheels I fitted to my S3 which was using RS3 custom brakes actually touched so I installed 3mm spacers and they were not visible without removing the wheel. They are so thin that the wheels still has loads of hub to sit on and should cause no problems.

Shaving a mm or 2 off the brake caliper might be the way to go then, if the fit really is that tight, spacers not an option and your planning to refurb anyway.

I ran wheels with what I recall as being 2 to 3mm clearance, including on track, without a problem

I've been running like this for 2 years with no problems.

Hi MikeFish, do you mean running no spacers with your RS5 Rotor?

[WTF its Arturo]

I run 255/30 on my RS5 rotors with 10mm spacers all around w/ ~2.1 deg camber. There is a massive difference from the way that my vehicle handles in comparison to the stock 19's with 275/30 Nitto NT05s with 10mm spacers. But that's largely due the tire selection/sizing. I'll use my stockers on the track, and even doing some spirited driving on the RS5 rotors i don't feel the same amount of grab + lots of rubbing with the rotors. I'm sure if I were using 275/30 with no spacers, it would be comparable.

Thanks for the photo. That looks tight as well. I will be happy if I have 2-3mm clearance.

But mine is so tight with probably 0.5mm to 1mm clearance that really worries me

WTF its Arturo, thanks for the feedback.

BTW, that's a very clean Sprint Blue, the silver Rotor looks amazing on your car

Yes, I have RS5 Rotors with no spacers. As you say it is bloody tight, literally no clearance. But, mine has been like that for 2 years through hot and cold and never had an issue.

Great MikeFish, thanks for your feedback

I run 4mm spacers with only a gnats bolx width between the calliper and S7 20" wheels for the last 3 years, done at least 15 laps around the Nurburgring and over 190MPH on the Autobahn with no issues whatsoever. People who says that normal car callipers expand when hot talk <beep>. My discs were so hot once that they had smoke coming off them when coming off the Nurburgring with no calliper wheel issue.

Good to know that mate.

For reference, roughly what is your brake/wheel clearance in mm?

Fixed that for you

[Covkiller]

You saw me then

Haha, someone clearly went for a late night blast night in the small hours last night....
