FYI, Spec Miata is staying with the RA1 for 2008
[quote]HELLO ALL, The TOYO RA-1 remains the spec tire for 2008 in all Spec Miata classes.
TOYO will continue building the complete line of fast moving RA-1’s in 2008 and quite possibly beyond. The gang over at TOYO are totally committed to providing you with the best ‘spec tires’ on the planet.
The fate of the RA-1 line has not officially been decided as of this time. TOYO may decide to continue the line well into the future or not.
FYI: My company, A.I.M. has been selling TOYO
RA-1’s since 1992. We provide trackside support for the SCCA and NASA in the San Francisco area.
Currently we are testing the R-888 on a couple of Nor-Cal Miata’s to better educate ourselves on what the R-888 needs to post fast, consistant lap times. It’s only for our own information. And YES, they are quicker ON MIATA’S if shaved rather than at full tread depth of 6/32. On the larger, more powerful cars this does not seem to be the case.
The tire has a different construction as well as tread pattern and therefore will require different camber/pressure settings to obtain the greatest performance from the tire. One cannot expect to simply change tires on a SM car with a zillion combined developement miles/race miles from a hundred different race tracks and a thousand different drivers to a different tire/construction without making some adjustments to the car. i.e. Most of the SM cars have been dialed in to perform their best on RA-1 tires!
Testing in the rain will begin shortly, so that we can better educate ourselves on their potential.
Thanks to Brad Rampleberg for using our tires to capture the 2008 SCCA SM Championship. [/quote]
