Got a track related question? I'll try to answer.

[Whooosah]

Yep all sounds normal now. Just me being paranoid on my first real brake job. Thanks again Mike for hooking me up with some great pads and fluid!!

Not really sure what you mean.

I put Baer (Alcon) calipers on my Vette. They have the standard metal spring clips our AP Racing ones do, but under the cross pin they have an additional spring to hold the pads in place and help with vibration. Look at the picture of Alcon's caliper for the 86: http://www.alibaba.com/product-detai...showimage.html

See the metal 'H' shaped spring under the Alcon name? It looks just like that only with the removable pin instead of Alcon name brace. I'd have to pull a wheel to get an exact pic but does that make a little more sense?

Do any of the forum vendors have a rapport with AP/Essex to find out if this clip is available? If I can find some spring steel sheets I could try to mock a set up for testing.

I get it now.

Let us know if you ever find something.

Essex @JRitt is a forum vendor.

Running Yoko AD08R in my class, and for the Timeattack festival this year I am permitted running semi slicks.
So I bought my self a set of 235/45-17 Yoko A048 (medium) for that race.
My question is, what's your experience time vice too be expected on a course that's about a 1.34-1.36.xxx on ad08r counterpart a A048 medium.
I know it's like comparing how long is a string
But in a guessing far shoot.
Some of you have most certainly driven both of them, and have some input?

Just talked to Essex, and they said they don't have anything that to quiet down the pads.

Answer to my self, and if anyone else is wondering about the performance of the A048 medium.
It's about a 1,2 second faster on the same car vs Toyo r888 on a 1.10-1.12.xxx course on a Mazda mx5 race car.

Guys, NEWSFLASH!

Race car parts do NOT make the same allowances for low NVH operation like street car parts.

Deal with it, or don't use race car parts on the street.

Be reasonable in your expectations guys!

I bought the AP sprint kit with street pads and track pads.

I knew from stock brakes track pads are going to make noise. Period. Unless you drive like a complete and utter **** on the street (which I don't mind if you do, but I can't)

Also the AP sprint kit will rust with any salt on them. I don't drive my car in winter salted streets.

Buy what will fit your application! If you want race car performance with street manners you are doing it wrong. You need to spend a lot more $ for something even close to that, think mclaren. If you don't have that money it is very fast and easy to swap pads, and all kinds of other parts.

Bottom line, you have to be reasonable in your expectations. You can get phenomenal street and track performance, but not with the same equipment.

[CSG Mike]

We're working on making a CSG x Brembo brake kit that will cover both spectrums at a reasonable cost...

Some of you may find some peace and quiet with a caliper that has harmonic damping...

People who swap in race pads just for the track, do you swap rotors as well? If not, do you re-bed in your pads at each track day?

[DocWalt]

I don't bother swapping rotors, just spend the first session making sure you're mentally "with it" and getting the pads bedded in.

I'm looking forward to having Carbotech street & track pads so I don't need to do the game of bedding in pads during the first session.

I use race pads that don't require bedding. Cobalt XR2s.

So I live in North Jersey and just ran VIR & Road Atlanta back to back (driving to both tracks). I don't know how you guys in the southwest do it. I was literally dying out there with the heat and humidity. I think I managed 14 out of a possible 20 total sessions. And at least half of them I ran short. VIR was a high of 90* and Road Atlanta was 98* on the Saturday. Just brutal.

Anyway, the car was OK at VIR but I was continually getting a CEL at RA, 0351. The first time I contacted my shop and they confirmed that it was a coil pack and they had experienced it as well and it was OK to reset it. (In 20 track days over 2.5 years, it's the first time I EVER had the check engine light come on in the car).

However, after that, the check engine light kept coming on after 2-3 laps into every session. The same code 0351. One of the guys from Chin said they see it all the time with hot temperatures and it's likely just the sensors overheating and not necessarily the coilpack itself. The problem is likely made much worse because I'm running an Open Flash header (& stage II tune) which is unshielded and is likely causing a tremendous heat build up.

When the check engine light came on, the traction control light also quickly flashed, even though I had the TC off. And the car seemed to hesitate at lower RPM and generally felt a bit sluggish. The car ran fine on the road all the way back to NJ and the check engine light hasn't come back on. So my question(s) are:

1. Do those of you who do track events with ambient temperatures > 90* frequently pull a cel 0351?

2. Has this eventually (or ever) resulted in a failed coil pack?

3. This may be somewhat obvious but would you recommend having the header wrapped or coated? I'm running an oil cooler but the stock radiator.

4. Was I right to pit when the check engine light came on or just being over cautious? (Frankly, my body was telling me to anyway. How in the HELL do you guys drive in 100* temperatures). Bleuch.

My next two events are Watkins Glen and Mont Tremblant so I doubt I'm going to see those kind of temperatures again but one never knows.
