Speedline CR-1 for Rear Wheel Drive @ GCRC

Speedline CR-1 Medium for Cement

CR-1 Speedline are the chosen control tyre for RWD rear tyres at GCRC, Gold Coast RC Raceway.

Set a massive challenge of finding a tyre that has similar speed to Countersteer 4wd cars, doesn't leave itself on the track surface and can still produce grip is difficult.

Testing over 20 different variations, some were super fast, some were super slow, some were great for 2 laps then terribly slippery, some were worn out in a session.

This tyre was a balanced result for our purpose and the specific needs of GCRC. Just like any track targeting realism and promoting close tandem drifting a control tyre is necessary.   

This is the flat camber design... but they still look pretty round to me. Edges are sharp so be careful when mounting.  Mounting is quite tight. you wont need 0-bands or foam inners. On many rim brands, you may need to remove the sharp edge with a knife and maybe trim the rim edge also.

I only need to mount up to the outer lip. Raised lettering means you can break out some paint and decorate.

What about driving... they look really slippery? Well we all know one tyre behaves incredibly differenty to another.  Stay tuned for a video from GCRC on the super polished concrete. They require a bit more "driving", but once you get used to the "feeling". You will enjoy these.

We are already enjoying the matched speed drift trains at GCRC after only a couple of weeks. Chassis are tuning into the feel and running door to door already.

Join the trains.
