I think people liked the A032 (the predecessor to the A048 ) but I haven't heard very good reviews of the A048. I bought a used set for my old CSP car and they were really bad. I think the sport package of the Elise comes with these tires and I don't think the Elise drivers like them very much.
Cosmos might have some insight b/c he's been through a couple of sets of those on his Elise. It should be interesting to hear how he compares them to the Star Specs he's running now.
