    In preparation for a track day at Carolina Motorsports Park in late April, I've outfitted my GTI with some sticky rubber. 18" wheels have been replaced with 17x8 Moda MD11 (the lightest I could find without spending an arm and a leg) and 225/45-17 Dunlop Direzza Sport Z1 tires. The suspension is stock.

    This will be the first time I've had this particular car on the track. Someone asked whether I was going to install special brake pads. Is that advisable? All I've done in the past with regard to the brakes is to flush the fluid (and of course check the pad wear) afterward. The car only has 10,000 miles on it, so I'm sure the pads are in good shape.

    Pads are going to be related to performance. If you want to stop harder and more frequently, pads designed for track applications will do so with less heat build-up and fading. Street pads are designed for longevity, not necessarily performance.

    That said, the real question is what you want to get out of you track day(s). I don't know your track resume, but it sounds like you're just getting started. If you're fast and are trying to eke out a few tenths of a second, then equipment changes can help (but so can investment in the driver). If, however, you're just out having some fun and learning the game, don't overcomplicate this. Pads may make your sessions slightly more enjoyable (less fade just as you're getting comfortable), but I wouldn't get bent out of shape if you go in with street pads.

    Once you're hooked, however, it'll be Katy bar the door. Every go-fast goodie you can think of will likely take on a new-found importance!

    Enjoy. Have fun. Be safe.

    Not only is CW right but if you are a newbie I would go even further and say don't even try and go fast because no matter how hard you try you won't. Try and learn to be smooth and listen to your instructor if you have one.

    Thanks for the feedback. I raced Formula Ford and SCCA showroom stock in the 70s and 80s, then quit for a long time and then picked up doing 24 Hours of Lemons about three years ago. I did two DE sessions at CMP two years ago and a Lemons race there early this month. This will be (hopefully) one more DE session to get signed off to do solo so that I can test the Lemons car. I don't plan to set any records, just be reasonably fast and smooth to get approved for solo. I think the stock pads will be okay for my purposes this time.

    I haven't driven stock GTI pads on track, but I suspect that you'll have to manage them.

    I agree with the others, go with a track pad.

    Oh, so you've raced before? Well then, don't worry about the pads. First, you'll need a 48' Featherlite stacker with lift gate, generator and full length awning; a nice toterhome to pull it; a golf kart; etc... You cannot do this track day properly for less than $500 k, trust me.

    Okay, that's only $499,500 over my budget. I'll see what I can do to stretch it a bit.

    One last question on the pads. Front only?

    Thanks again for the input.

    If you are going to CMP, tires and brakes suffer the most. If you want to get signed off for solo don't worry about speed but consistent and smooth matching laps.

    Thanks Karl. One thing that surprised just about everybody in this month's (full course) race was how much easier it was on brakes and tires than the short course, where one is braking and cornering a much higher percentage of the time.

    Your point is well-taken, though. When I did the DE in my Toyota two years ago, I had to alternate every hot lap with a cool one or the brakes would just go away.

    I'm also on the same page as you as far as getting signed off, which is my main goal. My lap times were quite consistent during the race (though they improved throughout), so I'm not too worried there.

    Thanks.

    Dan you are so right about the new configuration. I still hold a track record on each ( I guess the old one will be mine forever).
    The new course no longer has the autocross section and flows much better.

    While not a performance edge , if you are really a frugal guy , go to your local discount (or is it autozone?) and buy the pads with a lifetime warranty ;) Have new pads for every track day and save the stock for street use!

    I wouldn't put that garbage on my car. If one were to think that way, just save all the money and stay home, lol.

    We are reading from the same script, WCH! I'm seriously wanting to up-size the 50' High Tech to a 53' with two slides and the full hospitality extension! Don't forget the kiwi tiles...

    CW: down, boy. The OP is doing track days. I wanted to point him towards a starter setup he could manage with 3-5 crew. Something to assure victory, but not seem over the top. A roof over his head; a trailer big enough to accomodate the GTI and the T car, golf kart, nitrogen tanks, data debriefing station, tool cabinets, shock dyno, scales and alignment equipment, pit kart and a modest machine shop; a generator to power the tire warmers, espresso machine and lights for when the crew work through the night; maybe an observation deck on the roof; nothing fancy. Please keep your suggestions appropriate to the venue.


    Dinodan - great track day car, by the way!

    Smooth = fast. Just read you raced back in the 70/80's. I would absolutely NOT go on track without some racing pads. If you are halfway decent and likely you are from having done this in the past, you will (or could) eat through a set of street pads in 1/2 day or 3/4 of a day and then you are out of luck.

    Would also recommend steel braided lines. I wouldn't do a track day without at least that, but that is just me...

    Have fun and be safe.

    Please take no offense but I disagree on the SS brake lines. factory brake lines are made to last and will last many, many years. SS lines do not. They may be a better product but they require the same attention as the rest of a track car. I have seen them come apart at the crimp and I have also experienced it myself.
    The slight difference in feel is not worth the headache IMO. If one is capable of using their vehicle to the extreme it is not as important what equipment they have but if they know what to do with it.

    PS we all know what they say about opinions, lol

    I really appreciate all the feedback. What I have decided is that since this is (hopefully) my final DE session to get signed off for solo, my main goals are 1) smoothness and correct lines, and 2) consistent lap times. I'm going to run the stock pads as they only have 10K miles on them and are nicely bedded in. I will manage the brakes, doing cooling off laps if required, and will have the fluid changed afterward. This will give me a good baseline for any upgrades that might be required in the future. Thanks again.

    ditto the above. I completely toasted a front set of pads with 80% of the material left in just ONE day on the track. gotta get track-grade pads. (but not RACING pads.) TireRack or similar can advise you-tell them what you plan to do and they will point you in the right direction.

    Here are two cheap and easy mods to keep your brake temps down:

    1. if you have a metal "rain shield" behind your discs, remove that- it is just a big heat trap when at the track. unbolt it and toss it, or cut it off if necessary.

    2. check a VW / GTI forum and see if there are any aftermarket "air deflectors" that bolt onto your lower front A-arm and direct air in toward the rotor. Should be way less than $100 for a set. Anything to get more air in there will help.

    Cool brakes = better brakes.
