Corvette Brake Pads

All of the following pads were used with the OE rotors and calipers. After approximately 8 track days and 40,000 street miles, I finally replace the front rotors with another OE set.

Hawk HPS Brake pads
I started off with Hawk HPS pads since the car was a daily driver and track time was limited to the occasional autocross. These pads showed a mild improvement over OE. They were just as quiet but produced noticeably more dust than the stock pads. They had slightly higher initial bite than stock, but seemed to overheat and fade just as fast. At less than $110 per axle, they are a great entry level alternative to stock.

Hawk HP Plus
With track days becoming more frequent, I needed something to help with the fade that occurred after only 10 hot laps on a road course. Billed by Hawk as “autocross and club race worthy” I went through a single set of Hawk HP Plus pads and found them to be a noticeable improvement over the HPS. They clearly had more friction on initial engagement but something about the torque curve didn’t feel right to me. They would dig in hard for the first few seconds but they seemed to not want to grip any harder with additional pedal pressure. They also succumbed to a fair amount of fade after 15 hot laps. At only $130 per axle, I would recommend that anyone with a daily driver simply skip the HPS and use the HP Plus pads instead. With only a bit more brake dust and only a few squeaks now and then, these represent the best price for performance I can imagine for a street ride that also visits the track once in a while.

Performance Friction 01
When the Corvette was no longer needed as a daily currier, I moved to Performance Friction’s 01 compound. A few laps at Laguna Seca and it was clear these pads are in another league. They had greater initial bite and the high friction seemed to extend deeper and deeper as the brake pedal was asked to keep turn 8 from turning into an off track excursion. Lap after lap these pads proved to be consistent and easy to modulate with little to no fade, even after a 20+ lap session. Noted as one of the most popular club racing pad, it’s easy to see why. They carry a far higher heat operating range than the HP Plus and warm up after only 2 laps, yet don’t seem to be overly brutal on rotors. I have yet to autocross with these pads, so I’m not sure how they’ll perform when cold, but from daily driving my guess is that they will be slow to warm up and wont serve as an ideal pad for cold laps like that of a short autocross. Stopping distance on the street at low speeds is greater than the with the Hawks, they simply don’t like to be cold.

Dust is far greater than any other pad I’ve used, my street wheels show significant darkening after only a week of short drives around the block. Noise is also very obvious. These pads talk to you at pretty much any temperature while daily driving, mostly a light squeal when coming to a stop with gentle pedal pressure. Once up to track temperature they are either nearly silent or produce a more distinct metal on metal grinding sound. I’ve used these for two track days, or about 200 hot laps and for several months of spirited street driving on short trips. They are just now sitting at 1.5mm of material and ready for their first replacement set. Amazon currently carries the best price, around $280 for the front pads, manufacture part number 0731.01.15.44. I’m currently running OE Z06 pads in the rear but will likely move to these same 01 pads as well when they are used up.

It’s worth noting that these pads were installed at the same time as a basic duct system was added to my front rotors, so the lack of fade and overall improved track performance is surely a combination of the two items.

American Auto-X Series, Round 2

[qt:http://drivehard.net/racing/images/american_autox_3.29.09/american_autox_3.29.09.m4v 470 376]

A 4 year autocross hiatus and corded Hoosiers, a fast lap time do not make. It’s only fair the blame for being 4 seconds slower than others in my newly designated ASP class (thanks headers! pause, not) be equally spread between both the shear lack of viable rubber reft on my well worn A6′s and not having autocrossed more than once in the last several years. In the first heat I falsely assumed all those hours of seat time on road courses the past few years would have in someway kept my autocross skills sharp (enough), but alas that clearly wasn’t the case at all. While several sports may come back to you “like ridding a bike” this is not one of them. Proof of just how quickly you forget is in my first run, where I left the traction control on, incurred massive wheel hop off the line and finally landed in two 180 degree spins just a few feet from the starting line. Ugh. The rest of the day was spent trying to keep what felt like an unwieldy beast under control. It’s shocking how this sport can take a well mannered, neutral handling car that feels down right smooth being pushed around the sweeping apexes of a road circuit, and shines a glaring spot light on it’s (and the driver’s) lack of ability to gracefully manage sudden and dramatic weight transfer. She pushed, she oversteered, she bucked, she kicked. I thought back to the many years I spent convincing my ’98 Z28 that it was really meant for autocrossing and that pushing like a pig wasn’t actually the fastest method around the course. After several seasons and lots of practice trail braking, we finally came to an understanding and played a very competitive role in F Stock. Yet somehow, the infinitely better chassis of my Corvette was uncontrollable. Maybe it was the gas I used??

My laps peaked at a 44.0, still several seconds from being anywhere near decent. A farther cry still from a fantastic 38.xxx performed by an ASP Z06 and it’s driver who were one of the fastest of the day. So what’s the take away? I need some practice, and…new tires by the next event. 275/40 17s for the front at $560 and 315/30 18s for the rears (up from 295s) at $662 for a grand total for $1,222 worth of disposable rubber. Assuming autocrosses only and no track days, they should last all 16 of American Auto-X Series season. Next is suspension. That ASP Z06 was running 1,200lbs front and 1,000lbs springs in the rear along with double adjustable shocks. A far cry from my Z51 gear. All in due time…

Ferrari F430 vs Corvette @ Laguna Seca

It always strikes me as odd that so few people keep record of their lap times at track days. I completely appreciate Hooked On Driving’s philosophy of a non-competitive environment to provide a safe education. Practicing a particular skill or nailing the apex for a series of turns is what you’re there to focus on during a track day, and you can’t do that while fighting off aggressive traffic. But one key way to know if you’re making any improvement is to record your times. That education is even more valuable if you can compare times with someone who has more experience than you who might know a better line.

So, thanks to Kevin for posting his Laguna video and giving a yard stick to measure against. Putting our two in-car laps side by side you can really compare where we gain or loose time against each other.

Ferrari Challenge Race @ Laguna Seca

The 6th of 7 Ferrari Challenge races for 2008 landed at Laguna this weekend and through the help of a friend at a sponsoring company I spent two days watching this rare event from the hospitably rooms above the pits.

Sunbeam Tiger Club Autocross



Welcome to the Marina Airport, local home to sky divers and the words smallest autocross course. At least it seemed that way the day we joined the Tiger Owners Club for an event. All due appreciation to the Club for putting on a well organized day, but the course was so narrow and tight it surpassed fun and became a claustrophobic experiment.
