Woo-hoo, SP & it's slippery mini road course. I promise to stay off the grassy knoll this time. =)

Excited yet sad at the same time... Can't believe the season is coming to an end. Anyhow, if I added up the points correctly for this season, I think I'm set for X4 which means I can drive a different car for the last event. Anyone care to let me co-drive their car?? If not, I'll probably end up running my dads Z4 in S1

[Tochenzo]

Where in SP is this event held at? Is it the Kart track?

[AG]

Is it the Kart track?

yes

Wish I had that option...but I need an 8th place finish or better to clinch X2 after missing a few events!

I could make it interesting for the rest of X2 and bring the 4Runner instead....its 4.0L engine would put it in X2 Wonder if it could pull off an 8th place finish at Summit, lol.

[irish44j]

would be nice if points standings through 7 evens would be posted, btw, so we can all be sure that we have the correct math on our points!

[hepcatz]

AJ, you're always welcome to drive my car, I'm sure it would enjoy going fast for once... lol.

Ok, so I'm going to ask a really noob question here...actually 2:

1) I noticed a few guys putting shoe polish on the side of their tires. I understand it's to help them figure out how the tire is getting traction. My QUestion is how should you apply said shoe polish and how do you read the results?

2) 2nd noob question: I also noticed some guys spritzing something on their cards. I'm assuming its water. Is this to bring down the tire temperatures? Also wouldn't this lower the tire pressures to an undesired psi?

[Tochenzo]

I mark chalk/shoe polish on 3 parts of each tire (like a triangle) to cover a portion of the tread to the sidewall. The ideal tire pressure should allow the tire to rub off all of the polish on the tread and have it show starting from the sidewall. If there is polish showing on the tread, it means you need to let out some air. If there is no polish on the sidewall, it means you need more air.

[civicexracer]

Yes its water and yes it's to cool the tires. Spraying the tires with water really just cools the surface temperature. People do this becuase usually after a run or 2(also depending on abient and pavement temperature), the tires surface can get real hot, usually resulting in a "sluggish" or "slippery" feeling on the next run. Spaying with water keeps the surface temperature down enough so the tires maintain a good level of grip. As for the pressures, they don't drop mainly because you're only spaying a little bit of water on the surface and with only minutes between runs, there just isn't enough time for the water to cool fast enough to drop the pressure.

[ElGordoFeroz]

Hmm, I have much to think about now! Thanks for the answers guys!

[flohtingPoint]

I dont even spray my r-comps (which heat up MUCH faster than street tires) unless it's scorching out and the pavement can cook an egg. Heck, at the last AI, when I was co-driving Les' car, we didn't even spray his A6's and that was 8 runs (16 total counting morning and afternoon) with very little time between them. I've no idea why folks were spraying their street tires at the last BMW event, the ground was lukewarm at best.

Heavy cars and cars on qualifying tires are the ones that really benefit from spraying their tires. I watched Hoelscher use nearly a whole bottle on his DP MR2 at the Divisionals this year.

And on cool days you'll see some of the same, uh, fanatics putting blankets or other insulating material over their tires after each run in an attempt to keep some majic amount of heat in the tire tread.

[SamB325es]

I don't think spraying tires does much, like AJ said you are only cooling the outer tread. Right behind the wheel is a very hot brake disc, and the metal wheels, both of these are huge heat sinks. Spraying the outside of the tread doesn't counter them at all, I think once you take two turns at speed the tires are right back up to their previous temp. I gave up on sprayers, although on a really hot day they could be used to cool down the driver.

This is only opinion, I have no scientific data to back my claims.
AJ sprays his tires and he is faster than me so I am probably wrong...
