I have a large amount of "New Old Stock" parts for sale. This list is sorted for the available SR3 parts but I also have a lot of parts available for SR1, SR4, SR5, SR8, RXC, Spyder, and Raptures. T...

@mick_radical I don't know about cars other than SR3, but I assume many are similar. In my experience, I don't think that it is critical to get some exact height formula for the front spitter. The S...

@nautoncall I don't know. I would guess that leaded fuel would not cause issues other than some plug fouling, but the idea of making a 3 hour round trip and mixing fuel (which sounds dangerous) to sa...

You can run 110. You can run 98. You can mix fuel. The engine runs best on 100; the manufacturer has done the testing to know and advise this. Charlie answered this question in another thread on ...

@rjbender it's one of the 09s with the Life ECU but has Geartronics shift system. Hope their fly by wire system is better than some with the delay in throttle response. That makes me feel much bette...

@rjbender. I saw some of those but since it was for newer cars I didn't know it would be the same for older ones. I found some things similar on Radical's site but again I didn't think it would be r...

@rjbender I have a simple Aim Solo 2 DL on my car which is much less sophisticated but does use RaceStudio 3. My set up is similar to yours on the screen on my Sports Racer. That same screen you sho...

Ok aero gurus. In the side pods directly behind the front wheel there is a wing mounted vertically. Whats it do? I just had some repairs done and the guy doing them said it seems to wide at the front ...

Air is scooped from the side pods vents and directed to the rear, where the oil and water coolers are mounted. Generally corner speed is optimized in a high downforce road race car; the downforce ad...

@rjbender thanks. i did just that and it was OK. Still uncomfortable on the downshift, it doesn't sound like it enjoys it much.... and i don't know if putting the clutch in on downshift would help or...

I went ahead and did it. Done by Jet Hot in NC. Not cheap. Before the coating I took a temp reading on a spot on the exhaust pipe after letting car idle for a certain time and getting to a certain ...

@rjbender Awesome thanks. Do you apply any kind of revs to switch to first? Or simply disengage clutch slowly and let engine speed catch-up as it engages with drive?

@rjbender, Radical introduced the Life ECU and Life paddle shifting in late 2009 / early 2010. At that time paddle shifting was a fairly expensive option so quite o few of the early cars with Life EC...

To remove the stays from the chassis, there is a long socket head cap screw, I think M8, and nut and washer on the inside. Not that difficult to reach. If the stays are bowed, they can be gently ...
