@speedstarincdjb Hi Don. I have a recent story to tell about TPS which might be relevant; I assure you I do not mean to hijack your interesting thread. I was at the Radical Cup Sebring official te...

@rjbender Hi Rod. Yes, and your way makes sense. On the main wing, lowest down force would be the 4th from the bottom. "From the bottom" is specified in the user manual setup sheet, and I have int...

The Handling Guide has this to say about aero adjustments: This is a very brief description, but that is basically all there is to it. To determine whether a change has helped or hurt, one can ana...

My perspective is just for SR3. TL;DR: hole 3 from the bottom on the main wing, 6 from the bottom on the subwing, and no diveplanes on the nose. Very few race teams/drivers will run dive planes on...

I go entirely by feel to determine whether the fronts or rears are locking. You can feel the difference in your hands and body whether it is front or rear. It just takes a little practice, but if yo...

Update on the temperature strips. I purchased the temp strips from Pegasus.com who I think has the best price on these, $18 for 10 strips: RP-TEMP-230 Racetech 8-Temperature Strips, 160-230 F (71-...

On my recent engine swap, when I started it for the first time it was misfiring and not running long. I noticed when I connected the coil wire to the number 2 plug, there was no firm snap of the cap ...

I am not apologizing for Radical's high price parts, but this is prevalent in the race car business because the volume is so low, which means that if they do not make a lot of money on parts then they...

No, it records continuously, however the ECU should be "reset" for each engine swap so that you can easily keep track of total time and overrevs on the new or refreshed engine. I sent just my ECU to ...

Sorry about that -- I often overexplain things, which is a bad habit. I live in Nashville. Sebring is my favorite track because it is so difficult to go fast there, and because there are many opp...

@bird Hi Jay. There is plenty of room for both feet however it is necessary to wear driving shoes which are just a thin leather or suede and rubber sole the covers your foot. In an open wheel car, ...

Hi Ron. Both. If you need to increase camber, then you should loosen the inside hex nut and tighten the jamb nut on the rod end which will move the rod end outward. If you need to decrease camber, ...

I use left foot braking. It becomes second nature if you commit to it, but it does feel odd initially. The worst thing that can happen is that you get lazy when you are learning and you find the clu...

I spoke to Jonathan today and asked about uprights. Cost for original steel uprights for SR3 are about $1100 each. Cost for Billets about $1500. Yes, the lifing for the original uprights is about 4...

@bird I will find out dealer prices for you and report back but might take a day or two. Well, the car has been around over 25 years. Along the way the factory has made incremental improvements. ...
