Congratulations Jack @jackbaruth ! Great driving!

Hi Aaron (@speedsmith), welcome to the Registry! The SR1 is a great car, but I would recommend trying an SR3 also. There are reasons that the SR3 is Radicals most successful car. But I am sure you ...

@davidf, great write up… as usual. One item that I am not sure is correct is using on load time for engine overhauls. Although it is unintuitive, it is my understanding that Radical recommends using...

@schneller, you can get these parts from any Radical dealer. I understand the parts will fit on the XXs, the only thing I don’t know is if the radiators are the same in the side pods.

@speedstarincdjb, Thank you for posting pictures.

Hi Jeff (@jeff-alton), Welcome! I am looking forward to hearing more about how you like the car. Feel free to ask questions. 🙂

That made me think of something else to check. It is worth checking the fuel filter because sometimes there can be some fuel cell foam scraps in new fuel cells that can clog the filter. It is a bit ...

@speedstarincdjb, I agree with David, that sounds like the correct next step. I would also check the throttle body boots to see if they have cracked and are leaking. I would also check for any other...

I would also recommend getting a cover for that electronics box. It is hard to tell from the picture but it is likely either a Geartronics shift box, or perhaps a gear indicator box, or shift light b...

@nautoncall, No, the Sure-Seal connectors are not for charging. If your car doesn't have the Anderson plugs it most likely is not set up to be charged. You can add Anderson plugs to each battery if ...

The 4 open connectors are not used on track cars. The street legal cars have side markers and those plugs are for the side markers.

Hi Valentin (@bergfex), welcome to the Registry Forum. Many of the parts for the Gen 1 SR3's are still used on the newer cars so most parts are available through a Radical dealer. The exception is t...
