Came across this 5x6 setup with torsion axles https://makemytrailer.com/torsion-axles-on-5x6-enclosed-trailer and was wondering if torsion actually makes a big difference in smooth towing on the highway compared to leaf springs.

Anyone running a 5x6 or similar size for track days? How does it pull?

I have the programming cable and have been able to edit the display pages, however there are a few things in the ECU Stream that Radical has locked, even with the device key, they remain locked.

I'm also trying to understand the TPMS they used in these cars. I've been able to validate the box is transmitting to the CAN but I can't seem to get the data to read on the wheel. I can display it, but it never reads anything more than 1psi for all 4 wheels.  If I go into live view with the PDM32 I can see the data, right/wrong, but I can't seem to get that same info to the wheel.

I've seen other discussions on how their early XX's are configured and mine is: GPS to SmartyCam, Smartycam to EXP/CAN port and into the PDM.

Any feedback is appreciated, 

Kevin

I just had a crash on a hillclimb race, and i am looking for a rear wing, both sidepods (more needed the left one), and if it is possible front and back parts for an SR3 year 2007.

I don’t know if front part from newer Radical could fit on my SR3

I recently purchased a 2022 XX 1340.  After my first outing I am doing inspection and prep for my next even and noticed when nut/bolt checking the car that all the inner wishbone bolts were below spec.  I reached out to my dealer and I was informed that they have seen common issues when torquing to the recommended 30 lb/ft stated within the service manual.  They recommended torquing all inner upper and lower wishbone bolts to 20 lb/ft instead of 30.  Has anyone here experienced repeat failures of wishbone bushings or frame mounting structure.  Is this a common practice to use a lower torque value.  I also noticed the Nik Link Pivot bolt that uses a bushing was also torqued to the lower spec.  Thoughts?

 

Absolutely wicked car BTW.  I went out first day and PB'd over my Z06 by over a second.  I look forward to years to come with this car and a VERY different driving experience than a full sized car.

Looking forward to seeing anyone else at high plains raceway or PPIR. I'll take it to other tracks eventually, but going to keep it local while I learn the car. Looking forward to it!

Or recommendations? Some things seem pretty standard like carbon center seat and the race pack, but are people running the AP brakes upgrade, quiet exhaust, etc?

We are now in possession of SR3 113. We are looking to rebuild and maintain to run in Vintage races and HPDE around Texas. Our students will be mentored by local mechanics and other volunteers to get the car back on track. We are very excited and would love any insight, tips etc. We are also invited to attend the WEC event in Austin where the Radical Cup will be a support race.

The correct profile is: Radical Sportscars - PDM rec SR3-XX 1 Mbit/sec

I can see the profile on my existing configuration but can't seem to figure out how to either export/import or add it to the ECE Stream selection screen.

Anyone else dealt with this?
