How would a two driver work? Diane has expressed some interest...

Up to 2 people can share a car - they'd be placed in different run groups (typically D and C).

No convertibles, though.

I was thinking our new logo could be one of those Pee-on stickers peeing on a Benz logo and at the bottom it says. GOLDEN Gate Chapter.

Only one slight correction, but no changes to the grand order of things.

Looks like the current offerings in 225/50-15 are:

Kumho Victoracer V700
Toyo Proxes RA1
Toyo Proxes R888

You can also look at the Nitto Nt-01's

I don't know if these work for you, but they come in:

205/50-15
225/45-15

I know, but neither is the correct size.

Less than a half inch of sidewall difference, and just think of it as that in-between-normal-ratio dif swap? Haha. The r888's also come in that size.

I used to run short R-comp tires on cars that had the standard diff ratio. With my lower gears (4.10:1 vs 3.73), I'd be constantly shifting between 2nd and 3rd. No thanks.

We changed the brake fluid in Dinky today at MServiceGarage. Fluid was a little dirty but Adrian had the guys put in the ATE and I roadtested it afterwards, felt really good.

We must have engaged ABS at least 25 times Saturday, what a blast!

At 10in/sec the graph tops out at 475lbs. So there's your answer. 475lb, anything over and they blow or are at least ineffective.

For TDS, which runs will count?

Changing direction of course would only take swaping the timers and placing the finishing set coming out of the last sweeper. .

You really just need to swap the rj45 cables at the back of the timer...

Did you get a shorter gear set? Can you now recline your seat 7% faster?

Mommy, where do base points come from?

Tire size should be a 225 not a 255. Now that we see the data, how was it plugged in to assign the 39 point value? BTW my 2.8 is only 1 point more than the 1.9.

I think the "tire size" entry is based on roughly the largest size tire that can be crammed on the stock sized rim... in order to simplify things.

Right fellas?

correct. it is based on wheel width. As with most things, too much or too little is not optimal. Just because you can fit a tire on a rim does not mean it will work better than a smaller tire. Ask anyone who has crammed 245 on 7.5" wheels (not that I would do that..).
