I'll check out sizes, I bet my oem 19s are going to screw me with tire selection.
The RA1 were discontinued when the R888 was introduced. The R888 was to replace the RA1. However so many people complained and disliked the R888 that Toyo decided to remarket the RA1. Usually at the track I see the ligther cars use the RA1 and the heavier cars on the NT01.
