So, what did you do today?

Still gotta redo the TT, rebalance clutch, and get the trans new syncros. Racing has seriously eaten into its time/money budget so for now it sits.

Sweet; do I spy HPD concrete? And a 5th for dad and a not DFL for the boy in Novice PAX.

That's how the addiction takes hold.

Yep, I was a little better on the driving course portion. And regarding the addiction, the first thing he said when we got home was that he would have been faster on better tires, lol.

Found an interesting article/paper on rear diffusers.

It's Rocket science!

It's Rocket science!

As in applies to rockets. Theoretical equations with no practical applicability to race cars. Shape of the underbody, moving ground plane, rotating wheels, variable ride height, interaction with the flow over the top of the car, etc. If you are looking to build a diffuser, this is good stuff. If you are looking to put a rear diffuser on a racecar, don't confuse yourself with this stuff...

Took my driveshaft to be balanced and found it was "significantly bent" and required a new "tube" be installed. So, the cost of 41" of 3.5" 0.125" wall 6061-T6 plus cutting/welding/balancing is apparently $352... Gotta love "custom" parts. Lol

On the plus side, I took the car around the block today and no funny noises from the new gears or diff.

Also, found a loose front lower control arm bolt. Glad I checked them.

Finished the new front springs/perches in #34 this weekend. Next up is to do a good setup and finish the Texas flag install on the roof.
