I am running the GT-R Spec Vrs on the front, and when I spoke with Andy, he did mention that while I could drive to/from track, and on the street, the pads would be very noisy. And they are, very noisy, I hear this high-pitch, scream like sound every once in a while, and the sqealing is always there.

My other car is in the shop, so I am forced to drive the Type-R this whole week. Is it OK to drive with these pads on the street? Everything is fine other than the noise, and Andy didn't say anything about not driving on the street, so I am just checking to see what you all are doing. Not quite sure about the hazards of driving with track only pads on the street, if any.

 

My first set of Andie's pads squeaked pretty bad at constant pressure. Didn't hurt performance at all though. Cooked them at Expo, installed 2nd set, no squeaks.

 

It is fine to drive them on the street.

I drove home from nebraska yesterday with them on. On the highway after a few pumps, they stop good. Actually, they have great cold bite around town, but they are noisy.

There are really no hazards to driving with those pads on the street, but they are not in their optimal temp range around town, so it'll be like the first few turns on a warmup lap, where the pedal isn't really firm and the bite isn't nearly what it is when they are 'hot'. I've left them on for up to and week, and driven back from 5 track events this year with them on... no problems.

 

totally fine.

track pads tend to eat cold rotors - but I've never used these ones. if you are doing daily driving (i.e. a lot of short distance driving) keep an eye on the rotors. I once ate through a set of rotors in about a month with Porterfield R4 pads.

p.s. brake squeal is cool!

VR's ownza....

some squeak... but not that bad.

my rotors are about cooked so I left them on the car with the VR's for a while.

 

The noise is unavoidable with a high-coefficient of friction compound, as a matter of physics.

The spec(VR) can be driven on the street, but street use should be limited, for the various reasons mentioned here by other forum members. I suggest that you switch to a street compound at your soonest convenience if you plan on doing an extended amount of street driving. For the following week, you should be fine. Understanding that design characteristics of the spec(VR) compound is useful when using it on the street, e.g. optimal temperature range.

Best of luck...but switch back to a street pad as soon as you can.

I've been running the Cobalt VRs since ITR Expo 3. On street and track (4000+ miles).

 

squeal rules, same sound squirrels make when you run em over without hitting the brakes.

 

I've been driving on the street with them for over a month now without any problems.

 

as some mention, change the pads asap. i had the pads on my powerslot rotors for 2 weeks (2 weeks too long ) after an event. upon changing them out with the oem pads and inspecting the rotors, there was a "lipped edge". it was eating at the rotors.

please correct me if i'm wrong, but the squeal is a result of the the pads not being at optimal temperature. and while not being at optimal temperature, the pads are much more abrasive rather than "grippy".

however, the pads are great on the track.

kepani-who still owes the "d-hunny" owner some dough for the vr's.
