Default Sears Point

I just returned from 2 days at Sears Point. I went to a SpeedVentures event there. So, here's the lowdown.
First of all, its one hell of a drive from LA to the Napa Valley just north of San Fransisco. I hate those 5+ hour solo drives - I get all introspective and...well, that's a matter for my shrink.
Anyway, I arrive at the track on Thursday at 7:30AM and its cold and damp. The first thing that I notice in the paddock is the massive array of horsepower and race rubber everywhere. I begin to doubt the wisdom of driving almost 400 miles to get my ass kicked by everybody there. My stock motor and street rubber looks woefully inadequate. ZO6s, Vipers, a whole boatload of S2000s - almost all have had the motors breathed on and again almost all on either R compounds or slicks (!). I grab an instructor, drive my first session, and see that I'm lapping in the mid 2:30s - a lousy time, but it'll get better. For my second session, I get a different instuctor, who promptly shows me a different line. Such is life, he drives a Viper. The first guy drives some monster SCCA Ford silhouetted fire breather. Naturally, they have 2 different lines. During my last timed session of the day, I'm down to 2:11.xx - a 23 second improvement on the day. Thats more like it! When I get back to the hotel I lock my keys in the car and have to get AAA to open my door. They come within 25 minutes of my SOS - I was impressed.
Day 2 - beautiful weather - mild temperatures and clear skies. I have 5 sessions today. My plan is to start slowly, refresh my track memory in session one and get ready to go all Michael Schumacher when the track warms up later in the morning. So, my first session averages around 2:17. I'm down to 2:11s in the second and 2:10 in the third. I fiddle with the pressures on my new Azenis sports and decide to leave them at 39 front and 40 rear (hot). In the fourth session I actually manage to string consistent laps together - 3 consecutive 2:11s followed by 3 2:10s and then a 2:09.xx.

Session 5 I go out and experiment a little and do a 2:11 without really trying hard, but I'm tired and my poor little car is getting tired too, so I call it a day about 20 minutes early.

I go back to the paddock, let an instructor take my car out for 3 gentle laps (he's advising his brother on a car purchase but doesn't like the stock WRX suspension). He couldn't get enough of the DMS 50s though - he was very impressed.

Other times for comparison - a 320+HP WRX with R compounds was lapping in a hair over 2 minutes. So I'm giving up almost 100lbs in weight (my rollbar setup), 100 horses and he has R compounds versus my Azenis...I'm really pleased to be within 9 seconds. Supercharged, stripped, race rubber shod S 2000s are lapping below 1:53. The Vipers and 'Vettes 2-3 seconds quicker.

As I drive out of the paddock my "Check Engine Light" comes on...bugger it! Off to the dealer on Monday.

Thoughts
Sears Point is a twisty track with extreme elevation change, 2 hairpins and the infamous "Carousel". The track flows nicely from corner to corner. The new owners spent tens of millions of $ on this facility, but brother, they need to resurface the entire track. It is rough and has several surface changes in the corners. In the Carousel no matter what line I tried, I was unable to attain a speed faster than 65MPH. Any faster and tyre scrub just overwhelmed any throttle input. Understeer has raised its ugly head again!

I was running my StopTechs with Axxis Ultimates at the front and basically stock rears with Mintex1155 pads. I ran the Axxis pads for 2 days at Laguna as well. I still have about 40% left! I left early for all corners. I lift 100 yards before the hairpin that leads onto the main straight! I always baby my brakes. I know its costing me a bucket load of time on each lap, but I wasn't prepared to change to race pads this time. For the record, my ABS engaged only 3 times in 2 days.

SpeedVentures is a good group to go with. A little more relaxed than the Alfa Club, a LOT more horsepower at the track and I sensed a little more competitive spirit in the driving. For $375 I got about 5 1/2 hours on Sears Point - one of N. America's premier race tracks.

Things that I learned:
I'm now going fast enough to use racing pads.
I'm way quicker than I was 9 months ago when I started frittering away all my money.
I'm addicted.
Mellow Gold by Beck is one of the great albums of the last 15 years.
I'm sick of turning up to track events where I'm the only WRX making less than 240 at the wheels.
The world is full of 20 year olds with $40,000 WRXs

Its late. I'm tired. I've also got 1 1/2 hours of in-car video - so I might get around to posting some, or asking one of you kind citizens to host it for me - THE HORROR!

Willow Springs in 8 days!

Edit - the horror is true. I didn't turn on "steady shot" and I got a headache watching the video. Sometimes my stupidity amazes not just all those who know me, but also myself.

Nice write-up. Friday was a blast! Lots of open track. See you at the next Speed Ventures event - Laguna Seca.

Who's 320+ horsepower WRX was there turning over 2 minutes? On R compounds that car should be quite a bit quicker than that.

Our fastest lap was a 1:53.018, and our car weighed 3,320lbs.

Start using your brakes. That's what you bought those Stoptechs for! If you didn't experience ANY fade, use them harder. Use them until you feel fade. At that point, decide on a hotter pad.

Nice story.

Well, we're all just amateurs here. I can't speak for the other drivers, but I think I'd be right in saying that for most of those at the event, it was probably the 5th or 6th time (at the most) at any track and that is in our daily driver. By next year I expect all those who were at this event will probably be 5 or 6 seconds quicker - assuming regular track visits over the next 12 months. [ Added in edit. I know that I'll be annoyed if I can't be really close to 2:00 in the same car.] I'm due to be at Willow Springs in 6 days and I anticipate being at least 6 seconds quicker than my last visit there with the same motor and still on street rubber.

Incidently, I love my driving shoes. They are so much better than my old Nike Xtrainers that would always have me worried about hitting the brake and accelerator simultaneously. Worth 1/2 second/lap - seriously. I recommend that if you are at all interested in track driving and don't already own the correct footware, you should drop the cash and buy something designed for the track.

HoRo1,

I agree, but big power will make up for a lot of skill in laptimes. That 320hp car with R compounds has got big power on our USTCC car and probably 300 pounds less weight.

Back to your brakes - Have you felt brake fade with the Stoptechs? Or are you just taking it easy on the brakes because you are worried about the pads, even without feeling fade?

I would recommend driving the car as hard as you are capable and don't worry about the brakes until you feel fade.

I didn't experience any fade with my Axxis Ultimates, but then I was specifically trying to avoid fade - hence the lifting. I will run the StopTech Club Race pads at Willow Springs next weekend but frankly I don't think that I need to use them. I only brake at 1 and 3 with a touch at 9. I suppose that it is time to break in my new pads.

I was running consistent 2:10 and 2:11 laptimes and found another 2 secs by braking a little later on my Stoptechs (with club race pads). Ended up with a 2:07.9 best laptime on the day.

I'd love to get under 2 min. Gary, not sure what I would need to do though. I've got Vishnu stage 0, rear sway bar, endlinks, Prodrive springs, rear strut bar, and -1 camber.

I was pretty happy with the times on Falken Azenis. I had R-compound tires on the first session but didn't quite warm them up when I spun and caked them full of mud, so I pulled them off for the predictable Azenis. I figure the race tires are good for a few more seconds.

My setup produces some amount of oversteer, so I need to correct that. And I do the esses a little slow since thats where I spun out in the beggining of the day.

R compound tires are worth several seconds. Some R compounds are worth a few seconds even over other R compounds.

It sounds like you are new to race tires. What tire was it that you were using.

I'd say you did the smart thing going back to the Azeni's. They are more forgiving and you are more used to them. Keep doing track days with them until you are sliding them in every corner and you have complete confidence in your car control. Then I think the time would be right to try the stickier tires.

What caused your spin in the esses? Where did you go off? Remember, this is kind of like the kid falling off the bike and getting back on, even though he's a bit scared. Analyze your mistake, focus on the proper way and work your way back up to speed in the corner that bit you.

Yep, new to R-compound. I did do a few sessions with them (Michelin Pilot Sport Cups) at Streets of Willowsprings and spun on the first lap, but drove most of the rest of the day without incident. Interestingly, I got within 0.5 sec of my R-tire time with the Azenis (probably due to confidence level?).

Back to Sears point: I spun out on turn 8, beginning of the esses. It was on the second lap, so tires weren't warmed up. It was very sudden. What I realize now with R-compounds is there is very little noise at the limit.

Do different R-compounds have different noise levels at the limit? Or are they all quiet?

Thanks, Wylie
