I don't know exactly how to read into the SEB response to our most recent round of STU but I won't be surprised when there's no change.

Full tank? You have to be kidding. Saddle tank or not... that's insane.

My understanding is the SEB wants to increase attendance in STU by making the class cheaper. Or, I should say, introduce cars that are cheaper to build than the boost buggies. Theyr'e concerned that the 370z will bury the 350z if they were to move it and therefore... not make anything cheaper.

He isn't kidding. I'm a track guy, and it always happened around 7/8 of a tank. At Road America at 15/16ths in the carousel.

20 minutes was the longest session I could ever run before phunk's fuel system upgrade. Now I have taken it down to fumes.

Like Mike said about fuel starve. It happened to alot of us. phunk has a kit to fix this problem. It's a second pump inside the tank, on the left side. You can look all you want. You can't see it. I have have one myself. Better contact phunk quickly. His second batch maybe sold out.

Well, that sucks. A second pump or anything in the gas tank is not a legal modification for my class.

Oh well. I have to raise my weight target by 60lbs... I still should be able to get the car down to 3075 with a full tank of gas.

jesus really? some Auto-x rules are just too nazi

SPC front arm legal? Bushings can't have more metal than stock?

Ideas on improvements. Rather than getting bigger tires why not raise redline to 8000 rpm? You can still grab power up there and gives you a little more top end while keeping low end responsiveness.

Aluminum hat rotors? Huge rotating weight reduction.

Guys with blown oil pumps then motors would probably advise against that.

As for the SPC arms, I believe the rule is something like... "the ratio of metal to rubber cannot be greater than stock." The stock arms bushings look like they're the same ratio... although, I haven't done the actual math.

I do plan on getting the Z1 aluminum hat rotors. Those save 10lbs a corner.

I did think about raising the redline. Thoughts on what would be safe? **EDIT** I just read some of the other comments... I'd probably rather not raise the cars redline....
