I’d just fill the tank slowly and only add about 5 gallons whenever the fuel level gets near 1/4 tank. I overfilled the car once at Costco, and fuel ended up spilling from the back of the car. Definitely not a good sight.

I used Concord DMV and Martinez CHP office. I think they both are great. Just make sure you ask for the ones that understand SB-100. You can go to DMV first with all the paperwork (without your cat) , and get a temporary operation permit that is good for a few months. Then you can insure and drive the car around and get the BAR inspection for smog waiver, Vin verification at CHP, and back to DMV for the inspection. Be prepared for multiple trips to DMV:)

This is a much better engineering solution (vs just let the cable flying around). Thanks for sharing.

My wiper switch blew 5x fuses before it was replaced. FYI. I think the headlight issue might be related to wiring. Check the connector from the light to the harness.

You can check w/ @hahuang65as he had seen tach problem before. I thought the fix was a new gauge. How much gas do you currently have? I have noticed the gauge will read zero (or near zero) when the tank is less than half full. I used this "Caterham Fuel Gauge Correction Module - 2016+" from Beachman Racing, and it fixed the problem. My wiper had the same issue and Rich sent me a new wiper switch to fix the issue. Radiator fan should turn on when the temperature reached about 95F.

I was very close to buying a 2007 Exige S before ordering my 420R. The Exige S was great but doesn't offer the same level of thrill (vs Rich's Superlight I test drove earlier). I end up keeping my Evora GT and just added the 420R. One thing I would add to my car was the 620R dash.

Congrats on the new build. I think you are more than 50% for sure. Some mechanical part took me quite some time to install (e.g. diff cradle) Rich is awesome. He knows every detail of it.

Very comprehensive write up. Congrats on the newly registered cat in TX!

My 420R currently has R888s, but the front tires saw some notable wear after roughly 1,000 miles (alignment issue) of road use. I’m looking for a more road-friendly tire that still offers good grip. Which model would you recommend and where do you usually source them (local shop, online retailer, or dealer)?

Sold. Thanks!

I went the aftermarket route and now the OE side mirrors and mounts are for sale. The sale includes the door mounts and windshield mounts. There is a minor imperfection on one mirror. These are the part info from UK parts site: https://caterhamparts.co.uk/mirrors/134-mirror-sidescreen-and-iva-not-handed.html https://caterhamparts.co.uk/mirrors/2977-mirror-mount-kit-for-iva.html All for $80 plus shipping.

@pethierthanks for the advice, this is an option too. Since sport and track suspension uses different collar size, I'd have to source that part too. I am thinking about just getting the whole coilover setup and just swap it in without taking them apart. @MV8 I think I began to get used to the track suspension after 1000 miles so far. I'll take a look at Eibach's website to see if they offers same spring from factory catalog.

I am wondering if there are any Lotus Esprit parts.

After the CHP visit, I went to Concord DMV and got my CA license plate today. I started this process in July but I think I could have done it within a Month. Appreciate all the help from @KnifeySpoony @Nocturnal005 and @Slonie. I finally have a CA registered 7.

@Maggie S. IMO you'll still need the BAR inspection to get the smog waiver sticker (SB100). Or they may ask for smog checks in future reg renewal. But I just like the DMV you went to. Mine was very strict on CHP inspections.
