Here's my video from the rain race on Sunday. I'll post my quali video later, as that one's fun too! Laura's race also coming soon...

Full tread 888's. I loved them in the wet. It might be hard to tell from the video, but there's quite a bit of standing water, especially during qualifying. I found that with relatively high pressure (36 cold) they really resisted hydroplaning and still provided predictable grip.

Cheers,

Dean

That's what I was wondering they looked like they were very controllable!


What did you run the RA1 at (pressures) if you don't mind me asking?

I'd always preferred running RA-1's at lower pressures in the wet (24-28 cold). In all honesty, I tried the higher pressures in the 888's only because I read on Saturday night that higher pressures made a tire more resistant to hydroplaning. I was fast in practice so I stuck with 36 for qual and the race. A few others who were running lower pressures in practice tried 36 in qualifying and liked it a lot better. Danimal like the lower pressures better, though.

So, no scientific testing to arrive at this pressure, unfortunately.

If it matters, I had both swaybars disconnected.

Cheers,

Dean

I also ran the RA1's at 24 to 25 psi and liked it better then the higher pressure's.

Thanks for your input,I think alot of people would appreciate you sharing info like that. [thumbsup]

Dan,

I'll bet that the reason the lower pressures worked better for YOU was that you still had the front swaybar connected. The lower pressures were acting to soften the transitions of the car when you'd initiate a turn, and that effect probably over-rode the positive effect of higher pressures in hydroplane resistance.

Just a guess.

Did you feel like, with the higher pressures, that the car was sliding more on both ends or did it just understeer more?

Hey Deano, at the 6:38 mark in your rain race vid, aren't you going a tad fast considering how close you are to the E-truck? [Wink] [Wink] [duck]

Good point, but surprising. With the relatively soft springs they run in their class I figured they would have loved the rain.

Good question, Pat. T7 from about mid-point to exit was probably the grippiest part of the track in those conditions. My shift point from 2nd to 3rd was the same as in the dry. So, I felt like I was under complete control.

That being said, would I want to proudly offer this up to use an example in racing school for how to "slow down and control your car around emergency vehicles"? Ummm, probably not... [blush]

For the record, the workers were all in the truck, not outside of it attending to a car. I'd like to think that if workers were standing around, I would have slowed.

Cheers,

Dean

I was just giving you a hard time bud, but it does make a good discussion point, especially considering what happened down there a couple years ago. [Eek!]

Nice driving BTW- slipping through that puddle in T1 at 90+ mph, those are some big clanking cojones...

Dean, to answer your question...It understeered more on entry and was considerably more loose under acceleration

Thanx
