July 31, 2009: Suspension and brakes upgrade: First impressions permalink →
I picked up my MkV R32 from the dealer today. Besides doing the 20,000-mile service, I had them install Koni FSD struts and shocks; Hawk HP+ front and rear brake pads; ATE PremiumOne front rotors; and ATE Super Blue brake fluid.
In the city, the car brakes exactly the same as before, although pedal modulation seems better. Did I say exactly the same? Almost--now my brakes squeal. Usually not a lot, sometimes quite a bit. It comes mainly from the rear, where I am still running stock (and somewhat worn out) rotors. It doesn't bother me too much, surprisingly enough.
I tried several 70 mph -> 20 mph hard braking exercises, and the front pads exhibited pretty significant fade after 6 times or so. The stock pads NEVER developed fade, even on multiple tracks days at Watkins Glen. This worries me a bit. I did boil the OEM brake fluid in almost every track event, and I am hoping that the ATE SB will do the trick there. But I am left wondering whether stock pads would have been just a s good (and silent).
The suspension is quite nice. On the street, the ride is quite similar to stock, which is a good thing. On potholes, the suspension seems to be able to absorb them better and transmit less jerk to the cabin. When turning or doing slalom, the car is definitely more planted and exhibits less roll/bounce. That said, I was always quite happy with the R32's stock sport suspension--it just felt a bit underdampened, and a bit harsh on pavement defects.
I will try to post more thoughts as I get more seat time with the new configuration.
