Had such a blast today at my first trackday in my Silver car. It ran like a champ, and was sticking to the corners like glue! (IMG:style_emoticons/default/biggrin.gif) . (IMG:style_emoticons/default/driving.gif)

I did, however boil my brake fluid after flogging the car through the 3rd 30 min session. I noticed the fade early and was able to stay in low gear and cruise to pits, but it was scary none the less. It has 5-lug vented rotors, so this surprised me. I hear that old fluid might have been partly to blame? Any other suggestions? It was not a hot day (60's).

Agreed, old fluid and perhaps not high temp racing fluid. I use ATE Super Blue in everything and have been very satisfied with its performance. Brake fluid of the Germans! & made in Germany no less...

Though oddly I do not see the 'blue' variant I currently have stocked on my shop shelf... perhaps they stopped making that color or it is just out of stock? Either way, one of the nice features of ATE was the same chemical composition of their ATE Super Blue and Yellow, with just a different color so it was more evident when the entire system had been flushed out of the old fluid from year to year etc.

AHHHH! Apparently 'blue' colored brake fluid is now illegal in the U.S... or was for the past 15 years and ATE Super Blue has just now been caught. Not for functional reasons either... because someone might confuse it for washer fluid?!

See here: http://www.e90post.com/forums/showthread.php?t=878694
(forgive the BMW link)

I will cling to my last 2 cans of ATE Super Blue tightly! At least the yellow Typ. 200 is the same, no more easy flushes! Ha, that said I'd still recommend ATE 'TYP 200' as the yellow/amber version is known. 914 is looking good, next time you'll have to get a spotter with a camera track-side. Then we can asses the lack of body roll (hopefully) relative to the factory 914 suspension!

Ross, are you coming to the VW/Porsche reunion again?


Edit

Oh, I see you are in Colorado now. I guess you won't be making it...

Excellent Ross!

Obviously you don't know that brakes are for woosies! That said I had the same problems with my aluminum Willwoods.

I don't know what you have for brake ventilation, but I use stock 993 brake deflectors fastened to the A-arms (~$18 each). Keeps 'em a lot cooler without ducting and back-plates, and directs the air into the rotor centers. I use Motul. It's got a higher temp than Super-Blue and gives me a better pedal feel... at least I think it does. ATE 200 boils for me easily on the track

Your car looks great.

Shiny side up!

p.s. We met at an Arkansas MUSR a few years back. I was without my car that year (blown R&P a week before the event) but had fun anyway.

We went to a track day a bout a month ago. Two Boxters has brake fade because of boiling brake fluid. Both guys bleed the brakes and went back to the track with no more issues.

Before I take my car on any track, I would bleed the brakes and check pd thickness.

Fortunately I have one can of the blue juice, and have blue in it now, so I'll have at least three easy changes!

I don't have any pictures form the track day, but I do have some photos from autocrosses lifting the inside front wheel off the ground, which I hear is a pretty good indicator of stiffness. (IMG:style_emoticons/default/driving.gif)

I absolutely remember meeting you at MUSR! When you are uding thos ducts, did you remove the dust cover plates on the back side of the rotor?

No more super blue. Use ATE Typ 200. Same thing w/o the dye.

Stop using your brakes so much. (IMG:style_emoticons/default/biggrin.gif)

Get cooling ducts. If you have cooling ducts... read above. (IMG:style_emoticons/default/biggrin.gif)

I agree with Erc. Your brake fluid was old and needed a complete flush and bleed. Quit using your brakes so much. I rarely touch mine except to respond to traffic or set the suspension for a corner.

Oh, and if you really want suggestions, get off that fender. Body work is not cheap. (IMG:style_emoticons/default/lol-2.gif)

I don't know as much about the engine as I wish I did, as I only have a basic build sheet, but it was a 1.8 with 71mm crank+rods and 103mm pistons (2366). Its also got dual valve springs to let it rev a bit higher, though I hear the exhaust stops it from breathing properly far before the redline. The engine itself may be for sale here in a bit if it doesn't let go first!

Glenn, its a shame I didn't get out to one of the MCSCC events, I had no idea how much fun it could be!

Cooling ducts will be ordered shortly. I pulled the wheels off and upon close investication it looks like the metal pad backing is actually rubbing the aluminum of the hub a bit, I'm sure that's not helpful heatwise... I believe the front calipers are Volvo types. Maybe just grind the metal edge down a bit?

You are right about not hitting the brakes! But with the speedo reading 120(small tires though) I figured I ought to rub off a little speed (IMG:style_emoticons/default/biggrin.gif) .
