I had people try them already and say the rush is a different rubber. Work great on black crc and asphalt. Ofcourse using different compounds.

I doubt they have their own as of yet, given nothing has been posted on the Japanese Forums short of their recently released foams. Its not uncommon for manufacturers to rebrand another manufacturers tires, i.e. Ride etc.

sorry, please provide a link... i am still awaiting an email from my buddy in S. Korea. I would like to see the cost of tires be stable, and not turn a great class into a tire war!

EDIT: Confirmed by Jang Jihyun, Rush uses Volante tires.

depends on the conditions of the black carpet. I used both the Rush and CRC. One week the Rush were better the next the CRC.

I generally prefer Pit/CRC/TCS tires on black carpet. They are more consistent and usually the quickest over the length of a run.

I have tried the new Sweep 6304 F1 tires (updated black carpet tires with stiffer sidewalls and increased wheel offset. I was able to achieve a fast lap quicker than my fastest lap on CRC tires but they were more difficult to maintain consistent laps. They have tall sidewalls and are more prone to folding over and traction rolling (even after adding glue). Lot of steering though. I've tried the 6303 Sweep tires prior on a full aluminum chassis Xray X1 with good success.
