Radical has been controlling the release of information pretty tightly. I would imagine there will be controlled releases of small bits of information up until the formal release. I am looking forwar...

It isn't very often that Radical announces a new car but on July 4th the new Radical Rapture will be shown at the Goodwood festival of speed. If yo can't make it to Goodwood, you can watch the reveal...

John, The location may be different depending on what engine and ECU are in the car. What engine and ECU do you have? I am hoping that one of the members with an SR4 will chime in here, but here i...

Garrett, I would recommend contacting Matt (Forum name Trailbrake) from Trailbrake.com. You can send him an IM through the Forum. Matt is an Expert with data systems and is always happy to help. Cha...

John, I know the latest trend in bolt marling is paint pens, but I am stuck in the past. I have a long background in Aerospace so I use a torque stripe similar to what Graham uses. Here is another v...

Welcome John. You won't be laughed at around here for asking good questions like this. The SR4's are great cars and you will really enjoy it. There are some SR4 users on this site that can help ans...

I'm looking forward to seeing the videos! The position most people use is to mount the camera to the cross bars behind where the passenger sits. Here is a picture of my set up. Attachment : IMG...

I would give Spring Mountain a call. They have seen every conceivable issue dozens of times and will know the best way to fix it. And they will have the needed parts. They have been so helpful to m...

Nick, the first area I would look at is the plug where the tail light wires connect to the center body. The first question is if the plug is connected. The second thing to check is to make sure that ...

Hi Manny, sorry to hear about your half shaft. The only heavy duty shafts I am familiar with are the ones sold by Radical. They sell standard and heavy duty versions. Perhaps Dan at RLM knows anot...

To help visualize the difference between the different blippers. The first version of the blipper system used trigger wires going directly to the pneumatic throttle blipper (as shown in this picture)...

Posted by: John Parsons The shifter block uses 4 wires (2 for up and 2 for down shift). Each side should have a 12v supply, and the ECU (or GCU on older cars) pulls the corresponding wire to ground to...

That could definitely be the problem. How many wires are currently hooked up to the back of the plug? If there are three hooked up then the blue wire is needs to be repaired. If there are already fo...

Richard, I would double check some of your information. The 260mm and 280mm Radical Rotors are both 25mm thick according to the sales literature. Charley
