Hi @danamg, welcome to the Registry! I see from your recent posts that you are trying to decide between the RXC Spyder and and SR10 and are wondering why all of the dealers are pushing you toward the...

@helmutweber, remind me what your chassis number is and I will look it up in my notes. Hopefully I can tell you which you have. The difference between the Life and Geartronic systems is that the Lif...

Hi @nautoncall, I can add a little bit to David's excellent response. The Life Racing ECU has a battery that only gets recharged when the engine is running. People often mistakenly assume that if the...

Hi @nautoncall, As you mentioned the first RXC's came with a 3.7L Ford engine. Unfortunately the engine was a little underpowered for the car so Radical offered the 2.7L, 2.9L, and 3.0L V8 options be...

Welcome Nick (@nickallitt), Congratulations on getting your new Prosport! Unfortunately I cant help with your ratio questions but hopefully others will chime in.
