Good information. I really appreciate it when someone takes the time to post what the've learned and lets you know where to get what's needed. One my 2021 SR10 and the new 2022 I just got I've had the...

here's my first ever drive in my car at Donington UK. 6 months in the making! unfortunately this was the only (and i literally mean that) clear lap out of 78..... driving these cars on a general track...

This year was pretty unremarkable -- I lost the clutch my first weekend in January, but after I replaced it all was well the rest of the spring. The car has a new Radical engine, and new Kinsler DBW t...

Pardon me, but we are talking about an SR10, not an SR3. I have not worked on an SR10, but the owner's manual says: Attachment : Screen Shot 2022-07-14 at 5.30.50 PM.png Nothing mentioned abou...

Not ideal Clark! Sounds to me like either the sump fitting was not tight enough or the oil pipe was last done up cross threaded. If it was me I would continue to wind the pipe out with fitting and dra...

Just bought 2010 SR3 RS Chassis 542. Moved the car from Miami to Tampa. First NASA event at Sebring in June 🙂

@clark-darrah everybody who saw this initial pics had the same reaction, especially for big americans. It was already re changed and raised from those promo shots. Attached is a screenshot from radica...
