I've finally got the header piece of sheet metal and have the windshield frame pulled out close to where it should be. But, now the corner of the cage is pushed down maybe a couple of inches. When I inspected the tubes, I don't see any deformation in them or in the mount pads. So, I'm...

Last weekend I had the priveldge to be a part of the Long Beach Grand Prix, stationed at turn-1. I was drivers right response for the ALMS race on Saturday and the last Champ Car race on Sunday. I was right there when Paul Tracy lost his rear tire and slid into the run-off zone and Will Power...

I thought I'd document the rebuild of the Z3, mod-Zwei. Well, here's the rear suspension sub-frame in the back of the truck This was the barely perceptable tweeked side. On the other side: The twisting is more severe and toed in for extra stability :o Also notice the single...

You may have heard my complaints about not being able to keep up in ITE. Well last Friday, while watching the Sebring GT race, I saw one of our ITE lap record holders. Here's their story: http://www.world-challenge.com/news/story.php?ID=860 That's right I've been spanked by the very car...

Here's something I was wondering about after I asked about replacing motor mounts. Why is it not legal to drill holes in the passenger side seat and foot area for anything other than ballast weight? For reference, 9.1.3.9.l.3 "Holes may be drilled in passenger side footwell/seating floorpan...

I've started purchasing parts to put the race car back togeather. One thing I've though alot about but haven't pulled the trigger on are the motor and trans mounts. I'll just go with stock trans mounts, but what about the group-N or equvalant motor mounts? I'd rather have a mount that hold up...

I uploaded video to mySCCA page: Buttonwillow 16ccw Sept07 I'm trying to keep up with the Firebird in front of me. I'm catching up in the corners and he puts car lengths on me in the straights, untill my last time through the chicane. In the last frame you can just see the dirt flying into...

So I took the Z3 to a local body/frame shop and they told me not to bother with it, but get another. Now I've been looking online and havn't found many good replacement Z3's. Besides, it's too tail happy to be a good race chassis on our tracks. So these are some of the options I'm considering...

I'd love to run the Our Enduro at Buttonwillow, but as my car has a 12 gal fuel tank, I could only get half-way at best. They allow a team effort, with multiple cars. Josh would you be interested? James

I found out the reason I've been having issues with flat-spotting. My brake system is in fail-safe mode. So how do I replumb around the ABS valve? Will I need a new proportioning valve? I'm dealing with a BMW four wheel disc's, so I won't need a residule valve like a drum system. Looks like...

Just wondering if anyone's going to run the regional on Friday the 25th? I'll be in Ogden on bussiness and am making plans to possible work it on Saturday/maybe Sunday depending on my flight back to So-Cal. James

Hey ITAC members, On perusing the spec's for ITR I realized that all the BMW Z3's are classified with a 6-speed transmission. I've sent in a letter to the CRB to point out this error; however, I'm curious to see if the correct transmission and ratio's were used in classing the Z3. The proper...

When we got home Monday evening I recieved a copy in the mail. I was suprised by the picture on the top of page 27. Really it's as easy as they say. Don took the picture at Cal-Club's Pumpkin Run at Buttonwillow Raceway Park last October. James

Maybe this has been discussed before, and maybe it's time to touch on this subject again as consumer electronics goes in and out of style so fast. We have a Panasonic PV-250GS mini-DV camera that I used on my first couple of races on an I/O port mount. While using it on my second race I...

I'm just curious if anyone who's got ballast in their car, have you ever tried driving without it? Say during a test and tune day, or in an open ITE class. Did it take seconds off your best lap time? Did you go really that much faster than with the weight? Or is there a point that removing...
