Here's a video of the first flight of the A12 at Groom lake.

Agreed. If there are bottom bleeders I will use those first and then bleed from the top if the system is dry. The bottom bleeders are very helpful for gravity bleeding.

Any oil in the diff?

Something like this works very well and won't slip out. I build this on all my customer's racing exhausts unless they insist on something different.

Search man and please don't post off topic in stickies or FAQs.

FOA and FIA have pretty much lost their mind regarding F1.

The distorted thread, steel insert lock nuts will probably be your best option.

With a double and a triple disc clutch you normally have to go with an annular clutch release instead of the fork and slave cylinder setup. Like this pic:

I do not have a better moustrap and generally question the need for these aftermarket rear LCAs for 90% of the folks who install them. For those that do need (want) them, I recommend the arms from Modern Motorsports. There is no need to normalize welds on tubing under .125" in wall thickness. That's an old practice that is not called out by anyone, anywhere in a current welding spec. Even the NHRA (the last bastion of normalizing in CroMo) has backed off that requirement. What's most critical (assuming proper design and material selection) is proper fit up before welding (no gaps larger then the filler wire used) and proper welding with as little heat input as necessary to achieve proper penetration and bead size. A improperly welded joint on thin wall tubing cannot be saved by normalizing. It just makes things worse. Conversely, a properly welded joint on thin wall tubing does not need any post weld heat control beyond normal air cooling at room temperature.

Driving north out of Baker on the way to Pahrump (Spring Mountain Motorsports Park) I was behind a fellow competitor with a BMW M3 tied down to his trailer by the wheels. There are whoop-de-doos on that road and an oscillation developed as Jon mentioned. The sprung weight just started moving hard through its entire rage of travel front and rear for about 5 cycles. At the track the driver found both rear shocks were blown with oil everywhere and the right front shock had punched through the monoball on the Ground Control camber plate.

This is the 7th broken AZC rear LCA that I've seen of that style. I've repaired 3. It doesn't take a lot of power to break those, just a lot of lateral load and some curb hopping.

I think I have one in the the shop. I'll measure it on Monday. Also, I can ship via DBSchenker and it won't be that expensive especially if I ship door to airport. That's how I ship hoods and hatches to Europe, Australia, etc.

Frank might be getting a 1st gen RX7 shipped to him later this year. I can stuff the air dam inside of that car.
