I've even heard of some people running 10w60 in Duratecs.

Won't somebody please think of the children!

Wow, rare car and with an SB100 sticker...

How much track time is that and how much power is your car making?

Which pads in the rear? OEM pads I went through in 8 days, so I "upgraded" to Ferodo DS3000 and only was getting 5 days. And one of those sets had catastrophic failure on the 5th day (completely crumbled off of the backplate)

I think I heard that since the Sierra calipers are no longer available new/NOS, Caterham is rebuilding/remanufacturing old ones. Perhaps that has led to a decline in quality. However there are plenty of people on blatchat with very poor rear pad life, and even DPR ( I believe a popular UK 7 race tuning shop) says this on the page for the rear brake upgrade- "This upgrade provides far better rear brake pad longevity, much improved brake pedal compliance and a more robust and leak free system as found with the standard rear Caterham calipers. If you are tired of going through so many rear standard pads and discs after only a few track days this is a ‘must have’ upgrade!" Pads lasting only a few days and leak issues - yep that's my issue exactly...

Race rear brake upgrade. Finally ditching the garbage Sierra calipers.

subbed, as I feel this upgrade is in future some day

Is that full tank?

Roller barrels are an easy and well sorted (although perhaps slightly overpriced) addition that is easy to do during initial build that will net you some additional power and a lot more sound. And the throttle response is greatly improved from what I've read (I build mine with the rollers so I have no basis for comparison).

rebleed - the pedal will never be rock hard with the shitty flexing rear sliders but it should be decent Narrow shoes - yes - I can only drive it in proper racing booties. And even then I had to bend my throttle pedal to the right to make it easier to drive re: handbrake - I found that mine would barely hold the car until the rear pads were bedded.

Welcome- whereabouts in the bay are you (I'm in Fremont area)? It looks like a "sporty" spec - do you plan to track it? re: build blogs - when I built mine in 2021, I used this one (almost more than the actual build manual): https://caterham420detailedbuildblog.co.uk/

Caterham already solved this issue with the rad duct on the CSR. You could fashion up something similar if you have a vent in your nose cone. https://caterhamparts.co.uk/other/1724-radiator-ducting-csr-models.html

It's a standard ford TPS - you can pick it up at a ford parts counter, or get an offbrand equivalent online for dirt cheap.

I dunno, to me this just looks better too...
