Figured I'd post this here for everyone. Had fun!

For me the tool that was very useful for re-calibrating my brain to trust the downforce was the color map. I could look at a corner and internalize that at 90 to 100 mph the car is capable of 2.0 to ...

A couple from last weekend. The first one shows the acceleration out of #10 at Sebring with the corner worker looking on. The second one says downforce!!! That's Bishop's Bend which is a pure courage ...

Here's another one showing acceleration out of 17 (I think). The front right tire is nearly off the ground from weight transfer (inside to outside and front to back). I love seeing the vehicle dynamic...

Like many have echoed on here before, this thing is a blast. I'm still rather new to the track scene so I'm still coming to grips with the car. First session out my best lap was a 2:01. By the last se...

Geez Richard, you don't mess around! Nicely done. I'm just back from a track weekend, and will be taking stock of the car, including a thorough review of the brakes.

Today we had a participant visitor from Latvia 🇱🇻 . So now we have had participation from 101 countries. Welcome to all, and thank you for participating. Having a world wide perspec...

Some good video of a perfect time out at Sebring Raceway with an SR3 to chase.. I'm thrilled with the shift behavior of the car now, and you can hear and see how nicely the car shifts in the video. I...

Wow, you are making great progress! Here are some images to some of the torque values that you need. These came from the Gen 3 SR8 owners manual. Radical recommends using the latest manual because ...

John, we were using (SR8) the wilwood 120-13263 with termlock, 310mm rotors on the front and original radical calipers and 300mm rotors on the rear . rotor temperature was 250 front and 300 rear The ...

Most Radicals have very straight forward Chassis numbering methodologies. They usually have the model number followed by 5 digits which show the build order. For example the 22nd SR3 made was chassi...

I forgot to pick up mine from my last Sebring event... next up is late April. I'll have some more then, I hope! Here's another from February: Attachment : 1TM10672.JPG

I thought I'd add my own experiences with my 07 SR8. I've made nearly 10-15s improvements in my lap times (at Sebring) over the past two events in February and March, and I'm no longer embarrassed to ...

how cool. I liked how he balanced the weight transfer with brake and throttle at the same time

The SR8LM that held the Lap record for may years has been added to the Registry. Check out these links to see more about the car and watch it's record breaking lap. The car is currently for sale on ...
