SPB durability
Just wrapped up a WRL 12 hour WRL enduro in my fully legal PCA and NASA SPB.
306 laps
792 miles
Rear-ended once
Flat tire at hour 9:10
Finished P3 in GP1 and P3 overall (behind a very well built endurance oriented Boxster, and an E36 GTS2 car)
Will need new wheel bearings - and some minor repair, but otherwise fine.
If you've never done long enduros - I highly recommend it (best bang for your buck with seat time), and your SPB can handle it well.

Awesome. After grenading our motor in its debut race, I have some serious reservations about the reliability. This makes me feel marginally better but to compare apples to apples:
Do you run an external oil cooler?
Transmission cooler?
External fan to cool front brakes?

No. I ran my first year with one, but yanked it. I installed analog gauges and can monitor my oil pressure. It gets scary low in high g turns. Fortunately the tracks I run don't have banking or long high g sweepers.

My donor car at 52,000 miles on the motor. I never cracked the case, never did a thing to the motor. I have since put over 8000 miles racing on the car, and have never had a failure.
This includes 4WRL races over the last 12 months. And the car continues to be competitive and NASA, PCA, and WRL (multiple podiums).
I have an external transmission cooler, I do not run an external oil cooler, and I have vented to the front brakes and I am directing air with some custom fabricated ducts.

A bunch of technically/mechanically oriented folks out here in CO analyzed data and determined it wasn't necessary to run the accusump if you have the deep/baffled pan - not worth the significant weight that comes with the unit and extra oil. So I yanked it.
Some tracks may necessitate use of accusump, so I kept it in the event I need to reinstall.

The weakest part of the SPBs is the transmission and you can extend it's life by downshifting at the end of your braking and being smoother overall.
it's a durable car and we give them hell.

I don't run an accusump and have just an OEM pan + I race 12 times a year without issues.
