road rages suck. No traction at all. The slick you listed I have no idea. But there is an ebay seller that sells slicks that lookmlike that and are terible. Cheap.... but terible.
The GRP Rally tires were great too IMO, but it appears that they have been discontinued. That sucks. I used them all the time for parking lot oval. They were a great mix of traction an wear life. http://www3.towerhobbies.com/cgi-bin...?&I=LXMXB8&P=7
I have a set of these that are ok. Espescially for the cost $31 for a set of 4 mounted. But the sidewall is a little taller so they are not as precise feeling as the lower sidewall tires I listed above. http://www.amainhobbies.com/product_...ducts_id/17912
Guys on the Inferno Gt forum rave about Twister Tires. Seems they are only available here. They get a batch in every few months or so then sell them out in about a week.
