Update by Colin Wood to the BMW 435i project car

After spending a few days with BimmerWorld to get our 435i prepped for time trial duties, it’s time to take our BMW to its first big event: SCCA Time Trials National Tour at Virginia International Raceway, March 9-10.

[Live Thread: Prepping our 435i for SCCA Time Trials with BimmerWorld]

We’re expecting a sizable field of competitors as the event is sold out. The public is still welcome to spectate, though, and there will even be a car show on Saturday hosted by Driver Motorsports.

It looks like we’ll also get a chance to see how our 435i handles the wet, as the weather forecast shows lots of rain on Saturday.

Our entry time into the track got pushed back a bit, so it was a lot of bustling to get the car unloaded, get checked in and teched and get the car stickered up. But it's all set to go, and tomorrow is supposed to be a wet one. Forecast calls for rain all day, with up to 3/4-inch soaking VIR from sunup to sundown. James Clay will be stpping by to take a few laps in the Track Event portion of the festivities and I'm looking forward to sharing data and learning the wet line at VIR.

Some cool stuff in the paddock, too.

Tire Rack windshield banners make everything look cool.

Not sure it helps in anyway, but you can code the car with Bimmercode and have it display individual tire temperatures along with pressure on that screen. Like so:

Finally! Dry weather!

morning practice session was 45-degrees, but sunny and dry. Car is soooo much fun. Neutral and predictable, but it needs a little extra time to do everything because it's pushing 3650. Still, great grip from the Bridgestones in the cold, and supple, benign manners from the Koni and Eibach suspension bits. The Hawk DTC60s are a good track compound for the car and its heft. 
12 cars in the S3 class, so it's going to be a battle in our debut event.

Only issue after a dry session was a tiny bit of fender rub on the left rear. These are 18x10 ET25s with 285/35-18s. Totally acceptable, though.
